English

(b) have

"All of us" is a plural subject (first person plural), so it takes the plural verb "have". The sentence is "All of us have arrived yesterday" in the form tested; "has" and "had" do not agree with a plural subject in the present perfect.

(a) in, on

We sit "in" an armchair (we sink into it, enclosed by its arms) but "on" an ordinary chair (we sit on its surface).

(d) for, in, on

"Go for a walk" is the fixed phrase, "in the morning" is the correct time expression, and a pimple appears "on" the face.

(b) aren't you?

The statement is positive ("you are working"), so the question tag is negative and repeats the auxiliary "are": "aren't you?"

(b) To make efforts that are useless or vain

"To beat the air" means to struggle or fight without result, as if hitting empty air instead of a target.

(c) was

The sentence describes a past experience ("We had fun"), so the past tense is needed. "The bed and breakfast" here is a single place, so the singular "was" is used.

(d) invested

After "It is high time that ...", the verb is in the simple past subjunctive form to show that the action is overdue: "It's high time the government invested more."

(c) With

The phrasal verb is "dispense with", meaning to do without something or get rid of it.

(a) When I went to kitchen mom bought : bread, butter and Milk.

Of the four, only a colon is a punctuation mark that can introduce a list. The semicolons in (c) and (d) are wrongly used before a list, and (b) breaks the sentence with a full stop so that "When I went to kitchen" is left as a fragment. So (a) is the best choice among the options given.

(c) After bargaining for several weeks

The main clause "the owner and buyer finally agreed on a price" needs a modifying phrase. "After bargaining for several weeks" is a correct participial phrase; (a) has the wrong verb form ("had been bargain") and (b) makes no sense with "as if".

(a) A word will not be spoken by him.

Active "He will not speak a word" becomes passive by moving the object to the subject: "A word will not be spoken by him." Option (c) adds "never", which changes the meaning, so (d) is wrong.

(c) match

A match is a small stick of wood or cardboard that produces fire when struck by friction against a rough surface.

(a) were

"The principal and secretary" are two people joined by "and", so the subject is plural. The sentence is in the past, so "were" is used.

(a) On

People are seen "on the streets" – "on" is the preposition normally used with streets.

(c) stationary

"Stationary" means not moving, which fits "don't get off the bus until it is stationary". "Stationery" means writing materials.
