English Grammar — The Rules Tested Every Year

English Comprehension is 25 of the 100 questions in SSC CGL Tier-I and a full section again in Tier-II Paper-I. Roughly half of those marks come from pure grammar: spot the error, sentence improvement and fill in the blank. This chapter drills the handful of rules that the Staff Selection Commission recycles year after year — subject–verb agreement, tenses, articles, prepositions, degrees of comparison, pronouns, modals, non-finites, conjunctions and redundancy. Learn the rule, then learn the trap that hides beside it.

How the paper Actually Asks Grammar

The paper never asks you to define a gerund. It shows you a sentence and asks which part is wrong. So your revision must be recognition-first: you should be able to look at a verb and instantly ask "who is the subject, and is it singular or plural?" Four formats cover almost everything.

The four grammar question formats in the exam
FormatWhat the paper showsWhat you must do
Spot the errorA sentence split into four labelled parts, or four options each holding one partName the ONE part that carries the mistake — the other three are correct, so use them as clues
Sentence improvementOne phrase is underlined; four replacements are offeredPick the replacement, or No improvement if the phrase is already right
Fill in the blankA blank for a verb form, article, preposition or connectorRead the whole sentence first — the tense marker (since, yesterday, by 2030) usually sits far from the blank
Cloze test / passageA short paragraph with five numbered blanksSolve the easy blanks first; they fix the topic and tense of the paragraph
🎯 Negative marking changes your tactics
Tier-I deducts 0.50 mark for every wrong answer (Tier-II Paper-I deducts 1 mark in the English section). A grammar question you can reduce to two options is worth attempting — expected value is positive. A vocabulary question where all four words are unknown is not. In error-spotting, if you cannot name the rule that is broken, mark No error only when you have actually checked the verb, the preposition and the pronoun.
  • Scan order for error-spotting: verb → preposition → pronoun → article → word order. Ninety per cent of errors live in the first three.
  • Never judge a verb by the noun nearest to it. Judge it by the real subject, which may be five words away.
  • Keep a personal error log. The paper repeats the same twenty traps; your own mistakes repeat even more faithfully.

Parts of Speech — The Ten-Minute Refresher

A word has no fixed part of speech; its job in the sentence decides. In The round table is round, the same word is first an adjective and then a complement. The paper exploits exactly this: it puts an adjective where an adverb belongs (He drives careless for He drives carelessly) and hopes you read past it.

The eight parts of speech and the test that identifies each
Part of speechJobQuick test
NounNames a person, place, thing, quality: Delhi, honesty, committeeCan it follow the? the honesty, so noun
PronounStands for a noun: he, whom, itself, oneAsk which noun it replaces; if no such noun exists, the sentence is faulty
VerbAsserts action or state: wrote, is, has been keptIt is the word that changes with tense and with number
AdjectiveQualifies a noun: a diligent clerkIt answers what kind, how many, which
AdverbModifies a verb, adjective or another adverb: spoke softly, very goodIt answers how, when, where, to what extent
PrepositionLinks a noun to the rest: married to her, angry with himA noun or gerund must follow it: on going, never on go
ConjunctionJoins words or clauses: and, but, although, unlessCheck that the two joined halves are grammatically alike (parallelism)
InterjectionSudden feeling: Alas! Hurrah!Grammatically detached; rarely tested beyond punctuation
⚠️ Adjective where an adverb belongs
After an ordinary verb use the adverb: He works hard, She sings beautifully. But after a linking verb (be, seem, appear, look, feel, taste, smell, sound, become, remain) use the adjective, because it describes the subject, not the action: The soup tastes good (not tastes well), She looks sad (not looks sadly). Contrast He feels bad about it (adjective, his state) with He plays badly (adverb, his playing).

Subject–Verb Agreement — The Single Biggest Scorer

A verb must agree with its subject in number and person. The whole difficulty is finding the subject, because the paper buries it under intervening phrases. Strike out everything between the subject and the verb, then read them together: The list of candidates ~~selected for the interview~~ has been published — the subject is list, singular.

Subject–verb agreement: the rules the paper actually sets questions on
RuleCorrect exampleThe trap
Intervening phrase does not change the subjectThe quality of the mangoes was poor.were, pulled in by the plural mangoes
with / along with / as well as / together with / besides / in addition to / accompanied by — verb follows the FIRST subjectThe principal, along with two teachers, was invited.were; only and makes a compound plural subject
either…or / neither…nor / not only…but also / or — verb agrees with the NEARER subjectNeither the teacher nor the students were present. / Neither the students nor the teacher was present.Fixing the verb to the first noun instead of the nearer one
each / every / either / neither / anyone / everyone / nobody / many a — always singularEach of the boys was given a prize. / Many a student has failed.many a students; after many a the noun is singular too
one of the + plural noun + singular verbOne of my friends is a doctor.one of my friend (noun must be plural) and are (verb must be singular)
a number of + plural = plural; the number of + plural = singularA number of students are absent. / The number of students is rising.Treating the two phrases as interchangeable
Fractions, percentages and most of / some of / half of — look at the noun after ofSixty per cent of the work is done. / Sixty per cent of the workers are absent.Assuming a percentage is automatically plural
A measure of money, distance, weight or time taken as ONE unit — singularTwenty kilometres is a long walk. / Ten years is a long time.Using are because the number looks plural
Two nouns joined by and but naming ONE idea — singularBread and butter is a wholesome breakfast. / Slow and steady wins the race.Missing that the pair is a single dish or a single quality
Plural-looking singular nouns: news, mathematics, physics, economics, politics, statistics (as a subject), measles, mumps, innings, summonsThe news is disturbing. / Mathematics is my favourite subject.The final -s tempts you into are
Nouns plural in form and in use: scissors, trousers, spectacles, tongs, pliers, alms, riches, thanks, premises, surroundings, belongings, valuablesThese scissors are blunt. / His riches have not made him happy.Writing this scissor is; use a pair of scissors is if you need a singular
Nouns plural in sense though singular in form: police, cattle, people, gentry, clergy, poultry, verminThe police have arrested the suspect. / Cattle are grazing.The police has; also cattles, peoples in the sense of persons
The + adjective naming a whole class — pluralThe poor are often ignored. / The rich have their own worries.Writing the poor is, or adding -s as in the poors
A collective noun is singular when it acts as one body, plural when its members differThe committee has approved the plan. / The committee are divided in their opinions.Mixing the two inside one sentence: The jury has not agreed among themselves
A plural title, country or book name is one entity — singularThe United States is a federal republic. / The Arabian Nights is a classic.Reading the -s as a genuine plural
🧠 The one-second agreement drill
Cover everything between the subject and the verb with your finger and read the two aloud. The list … has, The number … is, A number … are, Neither the boys nor the girl … was. If it sounds wrong when stripped bare, it is wrong. This single habit converts most of the four to five agreement questions the paper sets every year.
⚠️ "One of the best … who have"
Two verbs, two different subjects. In He is one of the best players who have ever represented India, the main verb is agrees with He, but the verb inside the relative clause agrees with players — hence have, not has. Trace each verb to its own subject rather than to the nearest noun.

Tenses and the Sequence of Tenses

The paper rarely asks you to name a tense. It gives you a time marker and checks whether your verb form matches it. Learn the markers and you have learnt the chapter: since / for / already / just / yet / so far point to the perfect; yesterday / last week / in 1995 / ago force the simple past; by next year forces the future perfect.

Time markers and the verb form they demand
Marker in the sentenceRequired formExample
since + a point of time; for + a length of timePresent perfect or present perfect continuousHe has been living here since 2015. / … for eight years.
yesterday, last month, in 1947, two days agoSimple past only — never the present perfectI met him yesterday (not I have met him yesterday)
already, just, yet, so far, recently, ever, neverPresent perfectShe has already submitted the form.
Two past actions, one earlierPast perfect for the earlier action, simple past for the laterThe train had left before we reached the station.
by + a future timeFuture perfectBy December he will have completed the course.
when / till / until / as soon as / before / after introducing a clause about the futureSimple present in that clause — never willI shall wait till he comes (not till he will come)
It is / It has been + period + sinceSimple past after sinceIt is two years since I last saw her.
🧠 The three conditionals, in one line each
Type 1 (real): If it rains, we will cancel the match — if + simple present, then will + V1. Never if it will rain. Type 2 (unreal present): If I were you, I would refuse — if + simple past, then would + V1; with the verb be always use were. Type 3 (unreal past): If he had studied, he would have passed — if + had + V3, then would have + V3. Remember that will and would never enter the if half.
  • Verbs of state are not used in continuous tenses: know, believe, understand, mean, own, belong, contain, consist, resemble, seem, love, hate, prefer. Say I know him, not I am knowing him.
  • After No sooner and Hardly / Scarcely the auxiliary comes first: No sooner had he arrived than the meeting began. Hardly had she spoken when the bell rang.
  • A universal truth stays in the simple present even after a past reporting verb: The teacher said that the earth revolves round the sun.
  • For a wish contrary to fact use were: I wish I were taller. He talks as if he were the owner.
  • A timetabled future event may take the simple present: The train leaves at six tomorrow.

Articles — a, an, the and the Zero Article

The choice between a and an depends on the sound that follows, not the letter. A vowel sound takes an; a consonant sound takes a. That is why we write an hour (the h is silent, so the word begins with the /au/ sound) but a university (the u is pronounced /yoo/, a consonant sound), and an MP (the letter M is read /em/, a vowel sound).

The vowel-sound rule in action
Takes anTakes aWhy
an hour, an honest officer, an heir, an honourable mana hotel, a horse, a history book, a hospitalThe h is silent in the first group and pronounced in the second
an umbrella, an unusual case, an unclea university, a useful book, a unit, a European, a eweThe second group starts with the consonant sound /yoo/
an MP, an MLA, an SDM, an FIR, an LLB, an X-ray, an SMSa BA, a CA, a PhD, a UPSC aspirant, a JCBRead the letter aloud: M is /em/, but B is /bee/
an eleven-rupee stamp, an eight-hour shifta one-rupee note, a one-way streetone is pronounced /wun/ — a consonant sound
  • Use the for something already known or unique: the sun, the moon, the earth, the Prime Minister. Also with superlatives: the tallest tower.
  • Use the with rivers, seas, oceans, deserts, gulfs, mountain ranges, island groups and plural country names: the Ganga, the Arabian Sea, the Thar, the Himalayas, the Andamans, the Netherlands, the Philippines. But NOT with a single peak: Mount Everest.
  • Use the with newspapers, holy books, musical instruments and inventions: the Hindu, the Ramayana, play the flute, the telephone.
  • Use the before an adjective to mean the whole class: the blind, the unemployed, the elderly.
  • Zero article before languages, subjects, games, meals and most proper nouns: He speaks English. She teaches physics. They play hockey. We had lunch late.
  • Zero article in fixed purpose phrases: go to school, go to bed, in hospital, in prison, at home, by bus, on foot, at night. Add the only when you mean the building: The ambulance stopped at the hospital.
  • Zero article before an abstract or material noun used in a general sense: Honesty is the best policy. Gold is precious.
⚠️ Uncountables never take a or an
These are uncountable in English and cannot be preceded by a/an or take a plural -s: information, advice, furniture, luggage, baggage, scenery, machinery, poetry, stationery, equipment, evidence, bread, work, traffic, weather. Write an item of information, a piece of advice, two pieces of furniture — never an information or furnitures. The paper sets this at least once a year.

Prepositions — Appropriate Prepositions and Collocations

Prepositions cannot be reasoned out; they must be memorised as fixed pairs. The word decides its preposition, so store the two together as one unit: not superior and then a guess, but superior to. Below are the pairs the paper returns to most often.

Appropriate prepositions — the high-frequency list
Fixed pairExampleWrong version the paper offers
married toShe is married to an engineer.married with
congratulate … onI congratulated her on her promotion.congratulate for
superior / inferior / senior / junior / prior toThis model is superior to that one. He is senior to me.superior than, senior than
prefer … toI prefer coffee to tea.prefer than
different fromHis view is different from mine.different than (avoid in the exam)
suffer fromHe suffers from asthma.suffer of, suffer with
die of a disease, die from a cause, die for a causeShe died of cancer. He died for his country.died by cancer
deprive … ofThey were deprived of their rights.deprived from
insist onHe insisted on paying the bill.insist to pay
abide by a rule, comply with an order, conform to a standardYou must abide by the rules and comply with the notice.abide to, comply to, conform with
angry with a person, angry at / about a thingShe was angry with him but only angry at the delay.angry on him
familiar with a subject, familiar to a personI am familiar with the topic; his face is familiar to me.Swapping the two
tired of (bored), tired with / from (fatigued)I am tired of excuses. He was tired with walking.Using tired from for boredom
part with a thing, part from a personHe would not part with his old watch.part from his watch
responsible for a task, responsible to an authorityThe clerk is responsible for the files and responsible to the officer.Using responsible of
rely on / depend onYou can rely on her judgement.rely upon to (double preposition)
sympathise with, confide in, object to, refrain fromI sympathise with you but I object to your method.sympathise to, confide to, object against
consist of (parts), consist in (lie in)The team consists of eleven players. Happiness consists in contentment.consists from
🧠 Verbs that take NO preposition
These verbs are directly transitive; adding a preposition is the error the paper hides in plain sight — discuss (not discuss about), reach (not reach at), resemble (not resemble to), comprise (not comprise of), enter (not enter into a room, though enter into an agreement is idiomatic), marry (not marry with), order, request, describe, emphasise (not emphasise on), accompany, await (not await for), investigate (not investigate into), attack, lack, join, board, sign, ridicule. So: They discussed the proposal and reached the office at noon.
  • Time: at a clock time (at 5 p.m.), on a day or date (on Monday, on 15 August), in a month, year or long period (in July, in 1947, in the morning). But at night, at noon, at dawn.
  • Place: at a point (at the gate), in an enclosed area (in Kolkata), on a surface (on the wall). Note arrive at a small place, arrive in a country or city.
  • between two, among more than two: Divide the sweets between the two children and among the five guests.
  • beside means next to, besides means in addition to: He sat beside her. Besides English, he knows Tamil.
  • since is used with a point of time and a perfect tense; from is used with a starting point and any tense: He has worked here since 2019. He will work from Monday.
  • in spite of and despite mean the same, but despite takes no of: Despite the rain / In spite of the rain.

Degrees of Comparison and Pronouns

Two families of rules, both heavily tested. In comparison, the paper checks whether you doubled a comparative, compared unlike things, or used a superlative where a comparative belonged. In pronouns, it checks case, reflexive misuse and the choice of relative pronoun.

  • Never double a comparative or a superlative: more better, more superior, most best, more preferable are all wrong. Write better, superior, the best, preferable.
  • Absolute adjectives admit no degree: unique, perfect, complete, universal, ideal, extreme, entire, round, square, supreme, eternal, infinite, chief. So a unique idea, not a very unique idea or the most unique idea.
  • In the pattern the + comparative … the + comparative, both halves need the: The higher you climb, the colder it gets. The sooner, the better.
  • Comparing one member with the rest of its own group needs any other or all the other: Kolkata is bigger than any other city in the region. Drop other only when the groups differ: Kolkata is bigger than any city in Bhutan.
  • With only two items use the + comparative, not the superlative: He is the taller of the two brothers, not the tallest of the two.
  • Latin comparatives take to, never than: superior, inferior, senior, junior, prior, posterior, anterior, preferable.
  • Intensify a positive with very and a comparative with much: very good, much better — never very better.
  • Compare like with like. His salary is higher than mine (salary with salary), not higher than me.
  • elder / eldest only within a family and only before a noun (my elder brother); use older … than for comparison. later refers to time, latter to the second of two, latest to the most recent, last to the final one. farther is distance, further is additional.
⚠️ Case after than and as
When a verb is understood after than or as, use the subject form: He is taller than I (am). She writes as well as he (does). Compare I like her better than him (I like him less) with I like her better than he (he likes her less) — the case actually changes the meaning. But after a preposition always use the object form: between you and me, never between you and I.
  • A reflexive pronoun is never a subject. Myself Ramesh and Myself and my brother went are both wrong; write I am Ramesh and My brother and I went.
  • Some verbs need a reflexive object: absent oneself, avail oneself of, pride oneself on, enjoy oneself, acquit oneself, exert oneself, resign oneself, accustom oneself, reconcile oneself, avenge oneself. He absented himself from duty. She availed herself of the offer.
  • Other verbs must NOT take one: keep, stop, turn, move, bathe, hide, rest, open, qualify, spread. He kept quiet, not kept himself quiet.
  • Once you begin with one, continue with one / one’s: One should keep one’s promises, not his promises.
  • Relative pronouns: who for persons as subject, whom for persons as object, which for things and animals, whose for possession. Use that after a superlative, after all, only, any, none, nothing, same, it is, and when the antecedent covers both a person and a thing: This is the best film that I have seen.
  • Use each other for two people and one another for more than two: The two sisters helped each other; the five teammates encouraged one another.
  • Pronoun order is you, he and I for something pleasant, and I, you and he when owning up to a fault: I, you and he are to blame.

Modals and Non-Finites

A modal is followed by the bare infinitive — the plain first form with no to: He must go, never must to go. Two modals cannot stand together either: He will can do it must become He will be able to do it.

Modals: what each one signals
ModalMeaning testedExample
can / couldAbility, and possibility in theory; could also makes a request politeShe can swim. Could you lend me your notes?
may / mightPermission and real possibility; might is the remoter chanceYou may leave now. It might rain tonight.
mustStrong obligation, or a confident conclusion; the past is had toYou must wear a mask. He must be at home — his car is outside.
should / ought toAdvice and moral duty; ought is the only modal followed by toYou should revise daily. We ought to help them.
used to vs be used toused to + V1 is a discontinued past habit; be used to + gerund means accustomedHe used to smoke. He is used to waking early.
would rather / had betterPreference and strong advice; both take the bare infinitiveI would rather walk than wait. You had better consult a doctor.
need not / dare notAs modals they take the bare infinitive and no -sHe need not come. She dare not refuse.
must have / should have / may have + V3Certainty, unfulfilled duty and possibility — all about the pastHe must have forgotten. You should have informed me. She may have missed the bus.
Gerund or infinitive? Learn the verb, not the logic
PatternVerbs and phrasesExample
Verb + -ing (gerund)avoid, enjoy, mind, stop, finish, admit, deny, suggest, recommend, consider, postpone, risk, resist, practise, dislike, appreciate, imagine, keep, quit, tolerate, miss, cannot helpShe avoided answering. I cannot help laughing.
Preposition + -inggood at, interested in, insist on, succeed in, prevent from, capable of, accustomed to, addicted to, averse to, object to, look forward to, with a view to, in addition to, prior to, devoted toI look forward to meeting you. He is averse to changing jobs.
Verb + to + V1 (infinitive)agree, decide, hope, promise, refuse, want, wish, expect, offer, plan, intend, manage, afford, learn, seem, appear, pretend, fail, arrange, choose, deserve, hesitate, threaten, tendThey agreed to postpone the meeting. He failed to reply.
Verb + object + bare infinitivemake, let, bid, see, hear, watch, feel, help; also after had better, would rather, rather than, need not, dare not, but, exceptShe made him apologise. I heard the bell ring. He did nothing but complain.
Both forms, different meaningsstop, remember, forget, go on, try, regret, meanHe stopped to smoke (paused in order to) vs He stopped smoking (gave it up); Remember to post it (a future task) vs I remember posting it (a memory)
💡 A gerund is a noun wearing a verb’s coat
Think of -ing as a coat-check. Swimming is good exercise — here swimming is doing a noun’s job (it is the subject), so it takes a possessive before it just as a noun would: I object to his coming late, not him coming late. But in He is swimming, the same word is a present participle doing a verb’s job. Same coat, different owner.

Conjunctions, Parallelism and Redundancy

Correlative conjunctions come in fixed pairs, and both halves must sit before grammatically matching items. Not only did he arrive late but also he left early is clumsy; He not only arrived late but also left early balances two verbs against each other. That balance is what examiners call parallelism.

  • Fixed pairs: either … or, neither … nor, both … and, not only … but also, whether … or, no sooner … than, hardly / scarcely … when, such … that, so … that, too … to, not … but, as … as, so … as (in negatives).
  • No sooner pairs with than, never with then or when. Hardly and scarcely pair with when or before, never with than.
  • Although / Though pairs with yet, never with but: Although he is poor, yet he is content.
  • Do not use because and so together. Because he was ill, he stayed at home — or He was ill, so he stayed at home — but not both.
  • Unless and until already carry a negative, so never add not: Unless you work hard, you will fail. Wait until I return.
  • Lest is followed by should and never by not: Walk carefully lest you should slip.
  • For negative comparison prefer so … as: He is not so tall as his brother.
  • Keep the items in a series in the same grammatical form: He likes swimming, reading and cycling — not and to cycle.
  • Write The reason is that …, never The reason is because ….
Redundancies the paper sets year after year
Wrong (redundant)CorrectWhy it is redundant
return back, revert back, reverse backreturn, revert, reverseThe idea of back is already inside the verb
discuss about, emphasise on, investigate into, order for, request fordiscuss, emphasise, investigate, order, requestThese verbs are directly transitive

sufficient enough, but however, until and unless, also as wellsufficient / enough, but / however, unless, also / as wellTwo words are doing one word’s job
the reason is because, equally as goodthe reason is that, equally good / as good asCause or comparison is stated twice
⚠️ Word order: three quick fixes
First, an adverb of frequency goes after the verb be but before any other verb: He is always late, He always comes late. Second, an indirect question keeps statement order: Tell me where he lives, not where does he live; She asked what my name was, not what was my name. Third, a direct question inverts: Where are you going?, not Where you are going?
🧠 The five-check sweep for any error-spotting question
Run this sweep in order and you will finish a question in under twenty seconds.
(1) Verb — find the real subject, check number and tense marker.
(2) Preposition — is any fixed pair broken, or a preposition added to a directly transitive verb?
(3) Pronoun — case after than / as / a preposition; does one stay with one’s?
(4) Article — a versus an by sound; is an uncountable carrying a?
(5) Extra word — cross out any redundancy such as back, about, on, more. If all five are clean, only then mark No error.

Key takeaways

  • Strike out everything between the subject and the verb before you judge agreement. The list of names has, The number of cases is, A number of cases are.
  • With either … or, neither … nor and or, the verb follows the nearer subject; with as well as, along with and besides, it follows the first subject.
  • since and for call for the perfect; a definite past time such as yesterday forbids it. Never put will or would inside an if clause or after when / till / as soon as about the future.
  • a or an is decided by sound: an hour, an MP, an FIR but a university, a one-rupee note, a hotel. Uncountables such as information, advice, furniture and luggage take no a/an and no plural -s.
  • Store prepositions as fixed pairs — married to, congratulate on, superior to, prefer to, different from, deprived of, insist on, abide by — and remember that discuss, reach, resemble, comprise, emphasise, await and investigate take none at all.
  • Never double a degree (more better, most unique) and never compare a thing with a person: His pay is higher than mine, and He is the taller of the two.
  • After than and as with a verb understood, use the subject form (taller than I); after a preposition use the object form (between you and me). Myself is never a subject.
  • Modals take the bare infinitive and never pair up: He will be able to come, not will can come. Look forward to, object to and averse to are followed by the -ing form.
  • Correlatives are fixed: no sooner … than, hardly … when, although … yet, lest … should. Cut every redundancy — return back, discuss about, cousin brother, more better — and check parallelism in every list.

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. Spot the part that contains an error: The number of students in this school (A) / have increased (B) / considerably (C) / over the last five years (D).

    1. The number of students in this school
    2. have increased
    3. considerably
    4. over the last five years
    Show answer

    Answer: B — **have increased**

    The subject is the number, which is singular, so the verb must be has increased. The plural noun students sits inside the phrase of students and cannot govern the verb. Contrast A number of students have increased their scores, where a number of genuinely means several and takes a plural verb. Remember the pair: the number of … is / A number of … are.
  2. Fill in the blanks with the correct articles: It took me ____ hour to prepare ____ one-page summary.

    1. a / an
    2. an / an
    3. an / a
    4. the / an
    Show answer

    Answer: C — **an / a**

    Articles follow sound, not spelling. In hour the h is silent, so the word begins with a vowel sound and needs an. In one-page the word one is pronounced /wun/, which begins with the consonant sound /w/, so it needs a. The same logic gives an honest man but a university, and an MP but a BA.
  3. Improve the underlined part: He is _superior than me_ in mathematics.

    1. superior to me
    2. more superior than me
    3. superior than I
    4. No improvement required
    Show answer

    Answer: A — **superior to me**

    Superior is a comparative borrowed from Latin, and this family always takes to, never than: superior, inferior, senior, junior, prior, posterior, anterior, preferable. Since to here is a preposition, the object form me is correct — so superior to me. Option 1 also doubles the comparative (more superior), which is always wrong, and option 2 keeps the wrong than.
  4. Fill in the blank: Neither the manager nor his assistants ____ willing to take responsibility for the lapse.

    1. is
    2. was
    3. has been
    4. were
    Show answer

    Answer: D — **were**

    With either … or and neither … nor the verb agrees with the subject nearer to it. The nearer subject here is his assistants, which is plural, so the verb is were. Reverse the order and the verb changes with it: Neither his assistants nor the manager was willing …. This proximity rule is one of the most repeated agreement questions.
  5. Fill in the blank: He ____ in this city since 2015 and knows every lane of it.

    1. lives
    2. has been living
    3. lived
    4. is living
    Show answer

    Answer: B — **has been living**

    Since marks the point at which an action began and continues, which demands a perfect form — here the present perfect continuous has been living. The simple present lives and the present continuous is living cannot carry since, and the simple past lived would wrongly close the action off in the past. Note the companion rule: for marks a length of time (for eight years) and takes the same perfect forms.
  6. Fill in the blank: We are looking forward to ____ from you at your earliest convenience.

    1. hear
    2. have heard
    3. be heard
    4. hearing
    Show answer

    Answer: D — **hearing**

    In look forward to, the word to is a preposition, not part of an infinitive, and a preposition must be followed by a noun or a gerund. Hence looking forward to hearing. The same trap sits in object to, averse to, accustomed to, addicted to, used to (meaning accustomed), prior to and with a view to — all take the -ing form.
  7. Spot the part that contains an error: Please return back (A) / the book to the library (B) / before the last date (C) / mentioned on the slip (D).

    1. Please return back
    2. the book to the library
    3. before the last date
    4. mentioned on the slip
    Show answer

    Answer: A — **Please return back**

    The verb return already means to give or go back, so back repeats it — a redundancy. The correct phrase is Please return the book. The same family of errors includes revert back, repeat again, discuss about, emphasise on, enter into a room, join together, climb up and more better. In error spotting, always scan for one word too many.

    Answer: C — **Hardly had he entered the hall when the lights went out.**

    Option 2 obeys both rules: hardly is paired with when, and the auxiliary is inverted after it (Hardly had he entered). Option 0 wrongly joins although with but — it should pair with yet or stand alone. Option 1 writes then where the correlative of no sooner is than. Option 3 keeps statement order after scarcely; it should read Scarcely had I reached the station.
