English

(a) shall we

A suggestion beginning with "Let us" takes the question tag "shall we?".

(b) made

The causative "make" is followed by a bare infinitive without "to", and the past tense "made" fits "They ... him cut wood". "Got" would need "to cut", and "make" does not agree with the past tense.

(a) in

"In red ink" is the fixed phrase for the medium of writing, as in "written in pencil".

(c) see

"Had better" is followed by the bare infinitive, so: You had better see a doctor.

(b) colonel

The word for a military officer is spelt c-o-l-o-n-e-l (pronounced "kernel"). Options (b) and (c) are printed identically, and both show the correct spelling.

(c) has

"One of the girls" has the singular subject "one", so the verb is the singular "has": One of the girls has gone out.

(a) coward

A brave person is fearless, while a coward lacks courage.

(a) been stung

The past perfect passive is "had been + past participle". The past participle of "sting" is "stung", and "stunged" does not exist.

(b) The teacher told me that I could do if I tried.

In indirect speech "said to" becomes "told", the pronoun "you" changes to "I" to match the object "me", and the present tense moves back one step ("can" becomes "could", "try" becomes "tried").

(b) The wall is painted by the painter.

The active sentence is in the simple present, so the passive is "is/are + past participle": The wall is painted by the painter.

(b) didn't they?

"Had to" is the past form of "have to", which takes "did" as its auxiliary. The statement is positive, so the tag is negative: "didn't they?" (the plural "they" refers to "somebody").

(a) go

After the causative verb "make" in the active form, the bare infinitive (without "to") is used: "made you go".

(b) at, on

"Sitting at the table" is the fixed usage for a table used for work or meals, and "on the bench" is used for a seat one sits upon.

(d) goes

"Every day" shows a habitual action, so the simple present is needed, and the singular subject "Manish" takes "goes".

(a) Bureaucracy

The correct spelling is B-u-r-e-a-u-c-r-a-c-y.

(c) has

"Each" is singular, so it takes the singular verb "has" even when followed by "of the students".

(a) unknown

"Celebrated" means famous or widely praised. Its opposite is "unknown"; "renowned" is a synonym.

(d) beliefs

Nouns ending in "-ief" such as chief, belief and relief generally form the plural by adding "-s": beliefs.

(a) He said that he cleaned his teeth twice a day.

In indirect speech with a past reporting verb ("said"), the simple present "clean" backshifts to the simple past "cleaned", and "I" and "my" become "he" and "his".

(d) The accused was being questioned by the police yesterday.

The active sentence is in the past continuous tense ("was questioning"), so the passive is "was being + past participle". The object "the accused" becomes the subject.
