English

(c) for

"For" is used with a period of time (a decade); "since" needs a starting point.

(b) did they

"No one" carries a negative meaning, so the tag is positive, and "no one" takes the plural pronoun "they" in a tag.

(a) The

The definite article is used with a singular noun to speak of a whole kind ("The unicorn"), as in general statements about an animal.

(a) take off

"Take off" means to remove clothing or footwear.

(a) because of

"Because of" is followed by a noun phrase (the bad weather) and gives a reason; the others express contrast or need a clause.

(c) in spite of

"In spite of" is followed by a noun phrase and shows contrast: the pilot took off despite the poor visibility.

(a) aren't I

The question tag for "I am" is "aren't I".

(c) so

"So + adjective + that" is the correct pattern; "such" needs a noun (such a beautiful house).

(c) than

"No sooner ... than" is the fixed correlative pair.

(b) is

The subject is "nature" (singular), so the verb is "is".

(c) it feels rough

The linking verb "feels" is followed directly by an adjective.

(a) to pronounce

"Get someone + to-infinitive" is the correct causative structure.

(c) until

"Until" shows the action continued up to midnight.

(d) I hate being laughed at

The active clause "people laugh at me" is turned into a passive gerund phrase: being laughed at.

(b) two

"Mountain" is divided as moun-tain, which gives two syllables.

(c) I don't know where he live.

An embedded question keeps statement word order (no "does" or "did") and ends with a full stop, not a question mark.

(d) give

"Cattle" is a plural collective noun, so it takes the plural verb "give" in the simple present.

(c) a

"European" begins with the consonant sound /j/, so "a" is used.

(b) off

"Rolled off the table" means rolled away from its surface.

(b) fewer

"Fewer" is used with countable plural nouns (students) in a comparison.

(c) was

The sentence talks about a past day ("yesterday"), so the past tense of "be" for a singular subject, "was", is used.

(b) had had

This is a third conditional ("would have visited"), so the if-clause needs the past perfect: "had had" (had + the past participle of "have").

(c) any

After the negative "don't have", "any" is used before a countable noun. "No" would make a double negative.

(a) have

With "neither ... nor" the verb agrees with the subject nearest to it. "His friends" is plural, so "have" is used (present perfect with "so far").

(d) terrific

"Terrific" here means excellent, which fits praise for a popular singer. "Terrible" and "terrifying" are negative, and "terrorizing" means causing terror.

(d) in

"In the field" is the usual way to say crows are located within a field.

(b) such a

"Person" is a singular countable noun and "helpful" begins with a consonant sound, so "such a helpful person" is correct.

(c) thought

"Having + past participle" forms a perfect participle phrase, and the past participle of "think" is "thought".

(d) your house looks attractive.

"Look" is a linking verb and takes an adjective directly. "Looks like" must be followed by a noun, and the other options are ungrammatical.

(a) does he

"Hardly" has a negative meaning, so the main clause counts as negative and the question tag is positive. The auxiliary for the present simple is "does", giving "does he?".

(a) by

"By" is used for a deadline, meaning not later than 1:30. "Until" would mean the action continued up to that time.

(c) 90 years or above

A nonagenarian is a person aged between 90 and 99 years, that is, in their nineties. Among the given options, "90 years or above" is the closest.

(c) take off

"Take off" is the phrasal verb for removing clothing such as a jacket.

(a) being explored

The subject "space" receives the action, so the passive voice is needed. The present continuous passive is "is being explored".

(d) no preposition

"Marry" is a transitive verb and takes its object directly: "marry a Japanese". Here "marry" is followed by no preposition.

(c) fewer

"Houses" is countable and plural, so the comparative of "few", "fewer", is used. "Less" is used with uncountable nouns.

(a) to

Adjectives such as junior, senior, superior and inferior are followed by "to", not "than", so the sentence reads "junior to you".

(c) come (read as the simple past "came") "A few days ago" fixes a finished time in the past, so the simple past is needed, not the present perfect (has come) or past perfect (had come). Among the options, the simple past form is (c).

(d) ! "What a ..." begins an exclamatory sentence, so it ends with an exclamation mark.

(b) picnicking Words ending in "c" add "k" before -ing or -ed to keep the hard "k" sound: picnic → picnicking.

(a) a

"One-day" begins with the consonant sound /w/, so the indefinite article is "a": a one-day cricket match.

(b) will you

After a negative imperative ("Don't be silly"), the question tag is "will you?".

(b) because of

"Because of" is a preposition and takes a noun phrase ("the bandha"). "Because" and "although" need a clause, and "in spite of" does not fit the meaning.

(c) get

"Get something done" is the causative form for having a service done by someone else: get your house painted.

(c) what the time is

In an indirect question the word order is statement order (subject before verb), so "what the time is" is correct.

(c) can

"Can" expresses ability: although she is only five, she is able to read very well.

(b) fewer

"Houses" is a countable noun, so "fewer" is used instead of "less".

(a) into

We "change" one currency "into" another: change Rs. 500 into US dollars.

(d) to run

"Forbid someone to do something" is the correct pattern, so "forbid me to run".

(d) is ringing

The request "Can you answer it, please?" refers to the phone ringing at this moment, so the present continuous is used.

(c) had been

In reported speech, the present perfect "has been to America" becomes the past perfect "had been to America" after the reporting verb "said".

(d) No sooner "No sooner" is followed by "than" in the pattern "No sooner had he got home than it started raining". "As soon as" would not pair with "than".

(c) therefore The second clause is a result of the first (he is a best friend, so he tells the secret), which needs the linking adverb "therefore".

(b) no preposition "Discuss" is a transitive verb and takes its object directly: "discuss the matter". Adding "about", "on" or "of" is incorrect.

(a) sale "On sale" means offered at a reduced price. "Sell" is a verb, "sail" relates to boats and "cell" to a unit of life or a prison room.

(a) . The sentence is a statement (the clause "what is needed for you" is an embedded one, not a direct question), so it ends with a full stop.

(c) jackal The correct spelling of this wild dog is "jackal".

(b) intelligence A noun is needed after the possessive "Your", and the noun form is "intelligence".

(c) pull down "Pull down" means to demolish a building, which suits "old houses".

(a) What "What was the weather like?" is the standard question asking for a description of the weather.

(d) by

"By my watch" is the idiom meaning "according to my watch". So: It's 10 o'clock by my watch.

(b) with "Go for a walk with a friend": the preposition "with" shows accompaniment.

(b) did they The statement has the negative word "nobody", so the question tag is positive. The verb is past ("helped"), and "nobody" takes the plural pronoun "they", giving "did they?".

(c) have bled The present perfect is used for a past action with a present result: the finger has bled and the bleeding is still visible now.

(a) even though "Even though" introduces a clause of concession ("even though she fails the exam"). "Yet" and "and" do not fit here, and "in spite of" must be followed by a noun or gerund, not a clause.

(c) wouldn't have been "Had he worked hard" is an inverted third conditional (if he had worked hard). The result clause takes "would (not) have + past participle": "he wouldn't have been poor".

(b) I love my clothes being praised. The active "people praising my clothes" becomes the passive gerund "my clothes being praised".

(b) is "Along with" does not make the subject plural. The verb agrees with the first subject, "the politician", which is singular, so "is expected".

(c) formulae Nouns of Latin origin ending in -a usually form the plural with -ae (formula, formulae; alga, algae). The plural "formulas" is also accepted in everyday English, but "formulae" is the classical form.

(b) worse "Bad" is irregular: bad, worse, worst.

(a) at We use "at" with night: "at night".

(b) are being evaluated The assignments receive the action, so the verb must be passive. The sentence describes an action in progress, so the present continuous passive "are being evaluated" is used.

(b) by "By" with a time means "not later than" that time. With the future perfect, "will have got home by 4 o'clock" means she will already be home at or before 4.

(c) were walking A longer action in progress in the past (past continuous) is interrupted by a shorter action (past simple): "While we were walking ..., a dog began to chase us."

(b) will you The question tag for an imperative with "let me" is "will you?".

(b) has The subject is "the number", which is singular, so the verb is "has increased". (Compare "a number of", which takes a plural verb.)

(b) have "A large number of" means "many", so the verb agrees with the plural noun "people": "have applied".

(c) has been made The hotel is the receiver of the action, so the passive is needed. The subject is singular, so the present perfect passive is "has been made".

(c) has "Measles" is a disease name that looks plural but is treated as singular, so it takes "has".

(a) clearification The correct spelling is "clarification" (from "clarify"). The other words are spelt correctly.
