English

(a) what

"What you have done" is a noun clause acting as the object of "for".

(d) Bibek had some money in his pocket

"Did not have any" becomes the positive "had some" (past tense, "any" changes to "some").

(a) build

"Have + object + bare infinitive" (causative) is used here, so no "to".

(c) where I was

In a reported question the word order is that of a statement (subject then verb), and the verb shifts to the past: "where I was".

(c) Sunita told Gopal that she had been his best friend

"Said to" becomes "told"; "you" (Gopal) becomes "his", the speaker Sunita becomes "she", and "were" becomes "had been".

(d) Our teachers should be sincerely respected by us

The modal passive is "should be + past participle", and the agent is included as "by us".

(a) is

"The teacher and singer" has one article, so it refers to one person who is both. A singular verb is needed.

(b) themselves

The subject "boys" is plural, so the reflexive pronoun is "themselves".

(c) so that

"So that" expresses purpose: we go to the cinema for the purpose of enjoying ourselves.

(c) Unless

"Unless you work hard, you will not pass" means "if you do not work hard, you will not pass".

(c) the

The dinner is a specific one ("we had yesterday"), so the definite article is used.

(a) a

"Unique" begins with the consonant sound /j/, so "a" is used rather than "an".

(b) does not have any

Negative present of "have" (possession) takes "does not have", and "any" is used in negatives.

(a) did you do

A question in the simple past uses "did + subject + base verb".

(a) against

"Fight against" is the correct collocation.

(c) of

The adjective "jealous" takes the preposition "of": jealous of someone or something.

(d) where

The clause tells the place of Fewa Lake ("is located"), so the relative adverb of place "where" is needed.

(c) whose

"Whose" shows possession: the widow whose husband is dead (the husband of the widow).

(a) living

"Like" is followed here by the gerund to express a general liking: People like living in a big city.

(c) to change

"Forget" takes the infinitive when it means failing to do a task that must be done: do not forget to change your dress.

(a) is

Civics is a subject name ending in -s but is singular, so it takes the singular verb "is".

(a) herself

A reflexive pronoun agreeing with the subject Geeta (third person, feminine, singular) is needed: Geeta cleaned the room herself.

(c) My homework has already been finished

Present perfect active "have finished" becomes passive "has been finished". The adverb "already" sits between "has" and "been", and the agent "by me" is usually dropped.

(c) have been given

"Rita has given me a pen" in the passive is "I have been given a pen" (present perfect passive, subject "I" takes "have").

(b) to clean

"Get" in the causative sense (get someone to do something) takes the to-infinitive: Ram got his servant to clean the room.

(a) to have passed

The passing happened before the declaration, so the perfect infinitive is used: She is declared to have passed in the first division.

(d) on

"On" is used with a particular day, such as Christmas Day: he went home on Christmas Day.

(d) She loves having her photograph taken

The active "people taking her photograph" becomes the passive gerund "having her photograph taken". The other options either change the meaning or are ungrammatical.

(a) I suggested to my brother that we should go to some hill station for a change

A sentence beginning with "Let us" expresses a suggestion, so the reporting verb is "suggested" with "that we should ...".

(d) doesn't she

Here "dares" is followed by "to", so "dare" is used as an ordinary verb (not a modal). The tag is formed with "do": She dares to love, doesn't she?

(d) misandrist

A misandrist hates men. A misogynist hates women, a misanthrope hates mankind in general, and a misogamist hates marriage.

(a) Paradox

The statement seems self-contradictory, since a beginning is joined to an end, yet it expresses a truth: the end has started. That makes it a paradox.

(c) when she will get

In an indirect question the word order is that of a statement (subject before verb), so "when she will get married" is correct, not "when will she get".

(c) the manager's office

For a possessive relation with a person and a thing, the possessive form is natural: the manager's office.

(b) Should he come

Inverted conditional: "Should he come" means "If he comes". Option (a) is the wrong tense and (c) has the wrong verb form.

(a) remains fine

"Would come" in the main clause pairs with a present simple verb in the "if" clause for a likely condition: She would certainly come to see me if the weather remains fine. The other options are not grammatical after "if".

(a) of

The superlative is followed by "of all": That mistake was the worst of all.

(b) nothing

"German" and "Spanish" are languages used as uncountable nouns, so no article is needed (zero article).

(d) None

Rara Lake is a proper noun naming a particular lake, so no article is used.
