Sentence Structure & Transformation — Voice, Narration, Jumbles & Cloze

A large slice of the SSC CGL English section is not vocabulary at all — it is sentence engineering: turn this active sentence into a passive one, report this speech, rearrange these four sentences, fill these five blanks, point to the one part of the sentence that is wrong. These items are pure rule-recognition, their shape does not change from year to year, and each can be finished in fifteen seconds once the patterns are in your hand. This chapter hands you those patterns — voice, narration, synthesis and transformation, para jumbles, cloze and error spotting — with a worked example for every rule.

Active to Passive — the Three Moves

Every active-to-passive conversion is the same three moves, in this order. (1) The object of the active sentence becomes the subject of the passive. (2) The verb becomes the right form of be + past participle (V3) — and the tense of be copies the tense of the original verb. (3) The old subject moves to the end as by + object form (me, him, her, us, them, whom).

"The gardener waters the plants." → object the plants becomes the subject; waters is simple present, so be is are; V3 of water is watered; the gardener becomes by the gardener. Result: "The plants are watered by the gardener." Notice that the new verb agrees with the new subject — plants are, not plants is. That agreement check is where most marks are lost.

🧠 The one-line formula
Passive = Object + [be in the same tense] + V3 + by + Subject. The only part you must memorise is the middle bracket: is / is being / has been / was / was being / had been / will be / will have been. Read that list aloud three times; it covers every voice question the paper has ever set.
⚠️ Three traps in the options
Setters plant (a) the wrong participle — "A letter was wrote by her" instead of written; (b) the wrong agreement — "The plants is watered"; (c) the wrong pronoun case — "by she" instead of by her. Scan the four options for these three faults first; usually two options die immediately.
  • The agent is dropped when it is obvious or unknown: "Somebody stole my bag." → "My bag was stolen." Adding by somebody is not wrong, but the paper prefers the shorter option.
  • Some verbs take with, not by, for an instrument: "The letter was written with a pencil" (instrument) but "was written by the clerk" (doer).
  • A phrasal or prepositional verb keeps its preposition: "They laughed at him." → "He was laughed at by them." Dropping at is the commonest wrong option.

Voice — the Special Cases the paper Loves

Simple statements are the easy half. The marks are decided by imperatives, questions, sentences with two objects, and the impersonal "It is said that…" pattern. Each has a fixed template — there is nothing to reason out, only to recognise.

Voice-change rules for special sentence types
TypeActivePassive (the template)
Imperative — orderOpen the door.Let the door be opened. (or: You are ordered to open the door.)
Imperative — requestPlease help me.You are requested to help me.
Imperative — adviceWork hard.You are advised to work hard.
Negative imperativeDo not touch the wire.Let the wire not be touched. (or: You are forbidden to touch the wire.)
Yes/no questionDid she post the letter?Was the letter posted by her?
Question with whoWho broke the glass?By whom was the glass broken?
Question with what / why / whenWhat do you want? / Why did you break it?What is wanted by you? / Why was it broken by you?
Two objectsHe gave me a book.I was given a book by him. or A book was given to me by him.
General opinionPeople say that he is honest.It is said that he is honest. or He is said to be honest.
Prepositional verbThe nurse looks after the baby.The baby is looked after by the nurse.
have to / has toI have to do this work.This work has to be done by me.
Indefinite subjectOne should keep one's promise.One's promise should be kept.
🧠 Two objects: person first
With verbs like give, offer, teach, send, tell, promise, lend, pay, the safer passive makes the person the subject and needs no preposition: "I was given a book." If the option instead makes the thing the subject, a preposition must appear before the person: "A book was given to me." An option that says "A book was given me by him" is the trap — the to is missing.

Which verbs refuse the passive? Two families. (a) Intransitive verbs — they have no object at all, so there is nothing to promote: sleep, arrive, die, happen, occur, exist, rise, fall, seem, appear, come, go. "He slept" has no passive. (b) Stative verbs of possession, resemblance and measurement, even though they look transitive: have (= possess), resemble, lack, suit, fit, become (= look good on), cost, weigh (= measure), contain, comprise, consist of. "She resembles her mother" and "The bag weighs two kilos" have no passive.

🎯 Then what is a "passive of an intransitive"?
Two respectable exceptions. (1) Prepositional passive: an intransitive verb glued to a preposition behaves like a transitive unit, so the object of the preposition can be promoted — "The children laughed at him" → "He was laughed at." (2) Quasi-passive: a few verbs carry passive meaning in active form — "The book sells well", "The cloth feels soft", "Honey tastes sweet". No be + V3 appears, yet the subject is the thing acted upon. Recognise them so you do not try to "convert" them.

Direct to Indirect Speech — the Four Changes

Reporting somebody else's words changes four things and nothing else: the reporting verb, the tense inside the quotation, the pronouns, and the words of time and place. Work through them in that order and the answer builds itself. Also remove the inverted commas and the comma after the reporting verb.

Move one, the reporting verb. say with no listener stays said; say to a listener becomes told. So "He said to me, …" becomes "He told me that …", never "He said me that". Move two, the tense: if the reporting verb is in the past, every tense inside the quotation steps one pace back into the past.

Tense back-shift when the reporting verb is past
Direct speechIndirect speechExample
Simple present (writes)Simple past (wrote)"I write daily" → he wrote daily
Present continuous (is writing)Past continuous (was writing)"I am writing" → he was writing
Present perfect (has written)Past perfect (had written)"I have written" → he had written
Present perfect continuous (has been writing)Past perfect continuous (had been writing)"I have been writing" → he had been writing
Simple past (wrote)Past perfect (had written)"I wrote it" → he had written it
Past continuous (was writing)Past perfect continuous (had been writing)"I was writing" → he had been writing
Past perfect (had written)No change — it is already as far back as English goes"I had written" → he had written
will / shall / can / may / mustwould / should (or would) / could / might / must or had to"I will go" → he would go; "I can swim" → he could swim
would / should / could / might / ought to / used toNo change"I should go" → he should go
⚠️ Five situations where the tense does NOT shift
(1) The reporting verb is present or future: "He says that he is ill." (2) A universal truth: "The teacher said that the sun rises in the east." (3) A dated historical fact: "He said that India became independent in 1947." (4) A definite past time is stated: "He said that he was born in 1995." (5) Unreal / subjunctive wishes and conditions: "He said that he wished he were rich." Setters know that candidates back-shift mechanically, so at least one option per paper punishes exactly that.
🧠 Pronouns: the SON rule
Subject — first-person pronouns (I, me, my, we, us, our) change to match the subject of the reporting verb. Object — second-person pronouns (you, your, yours) change to match the object of the reporting verb. No change — third-person pronouns (he, she, it, they) stay as they are. Test it: "Ram said to Sita, 'I have brought your book.'" → I follows the subject Ram → he; your follows the object Sita → her. So: "Ram told Sita that he had brought her book."

🎯 Why the words of time change at all
Today, here, this are anchored to the speaker standing in a particular place at a particular moment. Once you report the words later and elsewhere, that anchor is gone, so the language must re-anchor: that day, there, that. Understand the logic and you will never need to recite the table — you will simply ask, "would the listener still know which day today means?"

Narration by Sentence Type — Orders, Questions, Exclamations

The four changes above handle a plain statement. A command, a question or an exclamation additionally needs a new reporting verb and a new link word, and it stops being a quotation at all — it becomes an ordinary clause with ordinary statement word order. That last point is the single biggest source of wrong answers.

Reporting verb and link word by sentence type
Sentence typeReporting verbLinkWorked example
Assertivesaid / told (with a listener)that"I am tired." → He told me that he was tired.
Question, yes/noasked / enquiredif / whether"Are you tired?" → He asked me if I was tired.
Question, wh-asked / enquiredkeep the wh-word"Where do you live?" → He asked me where I lived.
Commandordered / commandedto + V1"Leave the room." → He ordered me to leave the room.
Requestrequested / begged / entreatedto + V1"Please wait." → He requested me to wait.
Adviceadvised / urged / warnedto + V1"Take rest." → He advised me to take rest.
Negative commandtold / forbadenot to + V1"Do not shout." → He told me not to shout. / He forbade me to shout.
Exclamationexclaimed with joy / sorrow / surprisethat"Hurrah! We have won." → They exclaimed with joy that they had won.
Wish or prayerprayed / wishedthat … might"May you succeed!" → He prayed that I might succeed.
Suggestion with Let ussuggested / proposedthat … should"Let us go home." → He suggested that we should go home.
⚠️ Reported questions lose question order
A reported question is not a question any more. The helping verb goes back behind the subject and the question mark disappears. Correct: "He asked me why I was late." Wrong, and always offered as an option: "He asked me why was I late." Same for yes/no items — "He asked if I had finished", never "if had I finished".
  1. Exclamations lose their interjection and gain an intensity word: "What a beautiful bird!" → He exclaimed that it was a very beautiful bird. Alas becomes with sorrow, Bravo/Hurrah becomes with joy, Oh/What becomes with surprise.
  2. A greeting is reported with its function, not its words: "Good morning, sir," he said. → He wished me good morning. "Thank you," she said. → She thanked me.
  3. When one quotation holds two sentences of different types, each gets its own reporting verb joined by and: He said, "I am busy. Please come tomorrow." → He said that he was busy and requested me to go the next day.
  4. Vocatives move into the reporting clause: He said, "Ram, come here." → He asked Ram to go there. The name becomes the object of asked, so you inside the quotation would follow it under the SON rule.

Synthesis & Transformation — Same Meaning, New Shape

Transformation questions ask you to rewrite a sentence without altering its meaning. The test is mechanical: each pair of shapes has a fixed hinge word. Learn the hinges and you can convert in both directions. A simple sentence has one finite verb; a compound sentence joins two independent clauses with and, but, or, so, yet; a complex sentence has a main clause plus a subordinate clause beginning with that, because, as, when, though, if, so that.

Transformation patterns and their hinge words
FromToHingeWorked example
SimpleComplexparticiple → as / since / becauseBeing ill, he stayed at home. → As he was ill, he stayed at home.
SimpleCompoundphrase → and so / butIn spite of his poverty, he is honest. → He is poor but he is honest.
too … toso … thatso + adjective + that + cannot / could notHe is too weak to walk. → He is so weak that he cannot walk.
as soon asno sooner … thanNo sooner + inverted auxiliary … thanAs soon as he saw me, he ran away. → No sooner did he see me than he ran away.
SuperlativeComparativemore/-er + than any other + singular nounIron is the most useful of all metals. → Iron is more useful than any other metal.
SuperlativePositiveNo other + noun + is as … asIron is the most useful of all metals. → No other metal is as useful as iron.
Comparative (two things)PositiveX is not as … as Y (flip the order)Ram is taller than Shyam. → Shyam is not as tall as Ram.
Positive, "very few"Superlative, "one of the"one of the + superlative + plural nounVery few cities are as crowded as Mumbai. → Mumbai is one of the most crowded cities.
AffirmativeNegativeno one … who did not / never … / none butEverybody agreed with him. → There was no one who did not agree with him.
Affirmative, "only"Negativenone but (persons) / nothing but (things)Only Rama can solve it. → None but Rama can solve it.
Affirmative, "must"Negativecannot but + V1I must obey the order. → I cannot but obey the order.
Affirmative, "both … and"Emphaticnot only … but also (verb agrees with the nearer subject)Both Ram and Shyam were present. → Not only Ram but also Shyam was present.
🧠 The inversion trio — exact pairings
Only three sentence openers force the auxiliary in front of the subject, and each has one legal partner: No sooner … than, Hardly … when / before, Scarcely … when / before. So: "No sooner had he left than it rained." / "Hardly had I sat down when the bell rang." / "Scarcely had she spoken when the lights went out." Two combinations are always wrong and are always offered — no sooner … when and hardly … than.
💡 Think of it as changing gear, not changing car
A transformation must carry the same meaning at the same strength. "He is poor but honest" and "Though he is poor, he is honest" are the same journey in a different gear. An option that adds a new idea, or weakens must into should, or turns all into most, has changed the car — reject it however elegant it sounds.
  • Assertive → exclamatory: "It is a very sad sight." → How sad a sight it is! or What a sad sight it is! Use How before an adjective, What before a noun phrase.
  • Interrogative → assertive: "Who does not love his country?" → Everyone loves his country. A rhetorical question in the negative equals a strong positive statement.
  • Compound → complex with so that: "He worked hard and so he passed." → He worked so hard that he passed.
  • Never leave a double comparative or double superlative: more better, most best, more taller are all wrong. One marker of degree is enough.

Para Jumbles — a Repeatable Method

The paper gives four or five sentences labelled A, B, C, D (sometimes with the first and last fixed) and four possible orders. Never assemble the paragraph from scratch — work with the options, because they narrow four factorial possibilities down to four. The method below takes under a minute.

  1. Find the opener. An opening sentence has a full noun phrase as its subject, uses a / an for a first mention, and contains no backward-pointing word (he, this, such, therefore, however, also). Cross out every option whose first sentence fails this test.
  2. Follow the pronoun chain. A pronoun or possessive must come after the noun it stands for. If sentence C says "He fixed a meter" and only sentence B names an engineer, then B must precede C — and any option with C before B is dead.
  3. Follow the article chain. A committee comes before the committee; the indefinite article introduces, the definite article refers back.
  4. Read the connectors as arrows. However, but, on the contrary point back to something they contradict. Therefore, hence, as a result, so point back to a cause. Moreover, also, in addition point back to a first item. For instance points back to a general claim.
  5. Respect time order. At once, immediately precede within a month, which precedes within a year, which precedes today. Chronology beats intuition.
  6. Spot mandatory pairs. Some sentences cannot be separated: on the one hand … on the other hand; a question and the sentence that answers it; not only … but also. Find one such pair and usually three options collapse at once.
  7. Check the closer. Summarising language (in short, thus, perhaps the real question is) and the widest, most general statement belong at the end.
🧠 Two-end elimination
Look only at the first letter of each option, then only at the last. In most the paper jumbles the four options offer just two candidate openers and two candidate closers. Deciding those two questions — which sentence can start, which can only end — solves the item without your reading the middle at all.

Worked example 1. Arrange A, B, C, D. A. The idea spread to three neighbouring buildings within a year. B. A young engineer in Pune noticed that his building was wasting water. C. He fixed a small meter to every tap and pinned the weekly readings in the lobby. D. Consumption fell at once, because the residents had never known how much they used. Options:
(1) B-C-A-D
(2) B-D-C-A
(3) B-C-D-A
(4) C-B-D-A.

Reasoning. Openers first: C begins with He, so option 4 dies immediately. B is the only sentence with a full indefinite noun phrase — A young engineer — so B opens. Pronoun chain: C's He is that engineer, so C follows B; option 2 (B-D-C-A) breaks nothing yet, so check the time words. D says the fall came at once, A says the spread took within a year — so D precedes A, killing option 1 (which puts A before D). Between 2 and 3: D reports a fall in consumption, which can only happen after the meters are fixed in C, so C must come before D. Option 3, B-C-D-A, is correct.

Worked example 2 (first and last sentence fixed). S1. Public libraries are often called a luxury that a poor country cannot afford. A. On the one hand, they cost very little compared with a school or a hospital. B. This description survives because the benefits of a library are hard to count. C. On the other hand, what they offer — a quiet room, a shelf of books, a free newspaper — is unavailable to most households at any price. D. Both facts point the same way, yet neither appears in a budget. S6. Perhaps the accounting, rather than the library, is what needs reform. Options:
(1) A-C-B-D
(2) B-A-C-D
(3) B-C-A-D
(4) A-B-C-D.

Reasoning. Start with the mandatory pair: on the one hand (A) must be immediately followed by on the other hand (C). Option 3 puts C before A — dead. Option 4 puts B between them — dead. Now the demonstrative chain: B's This description can only refer to the description in S1 ("a luxury… cannot afford"), so B must sit right after S1; that kills option 1, which opens with A. Option 2, B-A-C-D, is correct — and it also ends sensibly, since D's Both facts summarises A and C, and its mention of a budget hands the topic to S6's accounting.

Cloze Test — Collocation, Grammar-fit, Discourse

A cloze passage removes five or so words and offers four candidates for each gap. Only three kinds of evidence decide a gap. Collocation — which word habitually keeps company with its neighbours (heavy rain, not strong rain; city after city). Grammar-fit — what form the slot demands (a bare infinitive after a modal, a gerund after a preposition, singular agreement after each). Discourse logic — whether the sentence continues, contradicts, illustrates or concludes what came before.

Worked cloze passage. "A city's traffic problem is rarely solved by building wider roads. Every new lane fills almost as soon as it opens, __(1)__ drivers who previously avoided the route come back to it. Engineers call this induced demand, and it has been observed in city __(2)__ city. The remedy lies not in supply but in __(3)__: making a car journey cost what it really imposes on everybody else. __(4)__, a road that is free at the busiest hour is a road that will be crowded at the busiest hour. Until such choices are made, road-widening will __(5)__ nothing but a costlier form of congestion."

  1. Gap 1 — because / although / unless / whereas. The second half states why the lane fills, so a cause connector is needed: because. Although and whereas would demand a contrast that is not there.
  2. Gap 2 — after / by / to / with. Pure collocation: the fixed English pattern for repetition is "city after city", like day after day. Nothing else fits the idiom.
  3. Gap 3 — demand / distance / decoration / duration. The sentence sets up "not in supply but in ___", and supply pairs with only one of these words: demand. Vocabulary questions inside a cloze are usually solved by such a pair.
  4. Gap 4 — However / For instance / Nevertheless / On the contrary. The next sentence is a narrower illustration of the general remedy just stated, not a contradiction of it: For instance. Every other option points backwards in opposition.
  5. Gap 5 — produce / product / producing / produced. Pure grammar-fit: after the modal will only a bare infinitive can stand, so produce. Note that this gap needs no meaning at all — the form settles it.
🧠 Cloze order of attack
Read the whole passage once before filling anything — the last sentence often decides the first gap. Then fill the grammar-fit gaps (fastest, zero ambiguity), then the collocation gaps, and only then the connector gaps, which need the argument of the paragraph. Finally re-read the passage with your five words in place; a wrong choice usually sounds wrong on the second reading.

Sentence Improvement, Fill in the Blanks & Spotting the Error

Three question formats share one skill. Sentence improvement underlines a part and asks for the best replacement, with "No improvement" as one option. Fill in the blanks removes one word — usually a preposition, a connector or a verb form. Spotting the error splits the sentence into four labelled parts and asks which part contains the mistake, with "No error" sometimes offered. In all three, you are hunting for a violated rule, not for a nicer style.

  1. Agreement. Find the real subject, ignore the words between: "The number of candidates who applied is large" — the subject is number, not candidates. With neither … nor and either … or, the verb follows the nearer subject.
  2. Tense consistency. Since + a point of time needs a perfect tense; for + a length of time. "She has been working here for three years", not since three years.
  3. Prepositions fixed by the verb. *prevent somebody from doing*, *look forward to doing*, *senior/junior to*, *superior/inferior to*, *insist on*, *comply with*, *married to*, *composed of*.
  4. Pronoun case and reference. After a preposition and after let, use the object form: *between you and me*, *let him go*. A pronoun must have exactly one possible antecedent.
  5. Parallelism. Items in a list must share a form: "She likes reading, writing and painting", never "reading, writing and to paint".
  6. Redundancy. the paper punishes doubled meaning: return back, repeat again, reason because, more better, cousin brother, discuss about. Delete the extra word.
  7. Countability and quantifiers. fewer / number for countables, less / amount for uncountables; each / every / one of takes a singular verb but one of takes a plural noun: "one of my friends".
Spotting the error — five worked items in the four-part format
Sentence, split A / B / C / DFaulty partCorrection and rule
The number of candidates (A) / who applied (B) / for the post (C) / are very large. (D)Dare → is. The subject is the number, which is singular; of candidates is only a modifier.
No sooner did I reach home (A) / when it started (B) / raining heavily (C) / and the power failed. (D)Bwhen → than. No sooner pairs only with than; when belongs to hardly and scarcely.
She has been working here (A) / since three years (B) / and knows (C) / every customer by name. (D)Bsince → for. Since takes a point of time (since 2019); for takes a duration (for three years).
Neither the manager (A) / nor his assistants (B) / was present (C) / at the meeting. (D)Cwas → were. With neither … nor, the verb agrees with the nearer subject, here the plural assistants.
He is one of the best (A) / players who (B) / has ever played (C) / for the country. (D)Chas → have. The relative who refers to players (plural), not to one.
⚠️ "No error" and "No improvement" are real answers
Candidates assume something must be wrong and invent a fault, converting a free mark into −0.50. Rule: change a part only if you can name the broken rule in words. "It sounds odd" is not a rule. If four honest checks — agreement, tense, preposition, word form — find nothing, pick the "no error" option and move on.
🎯 Why these items are the best minutes you spend
Tier-I gives 60 minutes for 100 questions — about 36 seconds each — with −0.50 for a wrong answer. Voice, narration and transformation items are the only English questions whose answer is fully determined by a rule you either know or do not; there is no reading, no judgement, no ambiguity. Clear them first, bank the marks, and spend the minutes you save on the comprehension passage.

Key takeaways

  • Passive = Object + [be in the same tense] + V3 + by + Subject. The whole topic is the middle bracket: is / is being / has been / was / was being / had been / will be / will have been.
  • Imperatives take "Let … be + V3" for orders and "You are requested/advised to …" for requests and advice; questions with who become "By whom was …?"
  • Intransitive and stative verbs (sleep, arrive, resemble, have, cost, weigh) have no passive; a prepositional verb keeps its preposition — "He was laughed at".
  • In narration change exactly four things: reporting verb, tense, pronouns (SON rule), and time-place words. Do not back-shift a universal truth, a dated fact, or anything reported in the present tense.
  • A reported question is a statement: "He asked me why I was late", never "why was I late".
  • Superlative to comparative needs "than any other + singular"; superlative to positive needs "No other … is as … as". Only three inversions exist: no sooner … than, hardly … when, scarcely … when.
  • In para jumbles work backwards from the options: fix the opener (full noun phrase, no back-reference), then chase pronoun, article and connector chains, then honour time order and mandatory pairs.
  • In cloze, settle grammar-fit gaps first, collocation next, connectors last; a connector must point in the same direction as the argument (addition, contrast, cause, example, conclusion).
  • For error spotting, change a part only if you can name the rule it breaks; with −0.50 negative marking, an invented mistake costs more than an honest "No error".

Practice questions (8)

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.

  1. Choose the correct passive form of: "The gardener has watered the plants."

    1. The plants have been watered by the gardener.
    2. The plants has been watered by the gardener.
    3. The plants were watered by the gardener.
    4. The plants are being watered by the gardener.
    Show answer

    Answer: A — The plants have been watered by the gardener.

    The active verb is present perfect (has watered), so the passive must be has/have been + V3. The new subject is the plants, which is plural, so the auxiliary is have, not has — that kills the second option. The third option shifts the tense to simple past and the fourth to present continuous, so both change the meaning. Correct: "The plants have been watered by the gardener."
  2. Change to the passive voice: "Shut the window."

    1. The window is shut by you.
    2. Let the window be shut.
    3. The window should shut.
    4. You are shutting the window.
    Show answer

    Answer: B — Let the window be shut.

    This is an imperative giving an order, and the fixed passive template for an order is "Let + object + be + V3": "Let the window be shut." (The longer alternative "You are ordered to shut the window" is also acceptable but is not offered here.) Option 1 turns a command into a statement of fact; option 3 leaves the verb active — shut has no be; option 4 is a plain present continuous statement, not a passive at all.
  3. Choose the best passive version of: "People say that he is a great scholar."

    1. He is saying that he is a great scholar.
    2. That he is a great scholar is said by people.
    3. It is said that he is a great scholar.
    4. He was said to be a great scholar.
    Show answer

    Answer: C — It is said that he is a great scholar.

    When the active subject is a vague group (people, everybody, they) and the verb is one of say, believe, report, think, know, consider, English uses the impersonal pattern "It is + V3 + that …": "It is said that he is a great scholar." The equally correct alternative is "He is said to be a great scholar" — note the present tense. Option 4 shifts to the past (was said), which changes the meaning; option 2 is grammatically possible but clumsy and never the paper key; option 1 is not a passive at all and even changes who is speaking.
  4. Report this speech correctly: He said to me, "I saw your brother yesterday."

    1. He told me that he saw my brother yesterday.
    2. He told me that he had seen my brother the previous day.
    3. He said me that he had seen my brother yesterday.
    4. He told to me that he has seen my brother the day before.
    Show answer

    Answer: B — He told me that he had seen my brother the previous day.

    Four changes are needed and only option 2 makes all four. Reporting verb: said to becomes told — so option 3 ("said me") and option 4 ("told to me") are both wrong, because said needs to and told forbids it. Tense: simple past saw steps back to past perfect had seen, which rules out option 1. Pronouns (SON): I follows the subject He → he; your follows the object me → my. Time word: yesterday must become the previous day or the day before, which rules out options 1 and 3.
  5. Choose the correct indirect speech: She said to him, "Why are you late today?"

    1. She asked him why was he late that day.
    2. She asked him why he is late today.
    3. She asked him why he was late that day.
    4. She asked to him that why he was late that day.

    Answer: C — She asked him why he was late that day.

    A wh-question is reported with asked, the wh-word is kept as the link, and the clause takes statement word order — subject before verb. Option 1 keeps the question order ("why was he"), which is the commonest trap. Option 2 fails to back-shift are to was and leaves today unchanged. Option 4 makes two mistakes: asked takes a direct object without to, and that must never be added before a wh-word. Correct: "She asked him why he was late that day."
  6. Change to the positive degree without altering the meaning: "Iron is the most useful of all metals."

    1. No other metal is as useful as iron.
    2. Iron is more useful than any metal.
    3. Iron is as useful as other metals.
    4. No metal is more useful than any other metal.
    Show answer

    Answer: A — No other metal is as useful as iron.

    Superlative to positive uses the fixed frame "No other + noun + is as + adjective + as + X": "No other metal is as useful as iron." Option 2 is a comparative, not a positive, and it is faulty anyway — it needs *any other metal*, since without other the sentence claims iron is more useful than iron itself. Option 3 says iron merely equals the rest, which loses the superlative claim. Option 4 is self-contradictory nonsense that names no metal as the most useful.
  7. Arrange the four sentences into a coherent paragraph.
    A. The idea spread to three neighbouring buildings within a year.
    B. A young engineer in Pune noticed that his building was wasting water.
    C. He fixed a small meter to every tap and pinned the weekly readings in the lobby.
    D. Consumption fell at once, because the residents had never known how much they used.

    1. C-B-D-A
    2. B-C-A-D
    3. B-D-C-A
    4. B-C-D-A
    Show answer

    Answer: D — B-C-D-A

    Opener test: C begins with He, a backward-pointing pronoun, so C cannot start — option 1 dies. B is the only sentence with a first-mention noun phrase (A young engineer), so B opens. Pronoun chain: C's He is that engineer, and the fall in consumption in D can only follow the meters being fixed in C, so the order is C then D — option 3 (B-D-C-A) is out. Time order: D happens at once, A happens within a year, so A is last — option 2 (which puts A before D) is out. B-C-D-A is correct.
  8. Select the best improvement for the underlined part: "Scarcely had the meeting begun than the power failed."

    1. then the power failed
    2. that the power failed
    3. No improvement
    4. when the power failed
    Show answer

    Answer: D — when the power failed

    Only three inversion openers exist and each has one legal partner: no sooner pairs with than, while hardly and scarcely pair with when (or before). The sentence begins with Scarcely, so than must become when: "Scarcely had the meeting begun when the power failed." Then is an adverb, not a conjunction, so it cannot join the two clauses; that is used after so … that, not after scarcely; and since a real rule is broken, "No improvement" is wrong.
