Answer: (b)

Both 'till' and 'while' do not fit in the context of the meaning sought to be conveyed in the given sentence; (a) will be grammatically incorrect.

Answer: (d)

Options (a), (c) and (b) will not convey the meaning intended. Here 'should' is used in the sense of 'If you should'; one can omit the 'If' and place 'should' first.

Answer: (b)

'Unless' means 'but not if'.

Answer: (c)

After negative statements, we use the ordinary interrogative. E.g., You are not coming, are you?

But after affirmative statements, the negative interrogative is used (as in the given question). The subject and the linking verb are to be retained as such.

Remember this about question tags: if there is an auxiliary verb in the statement, it is repeated in the question tag (He is a wonderful man, isn't he?); for verbs other than auxiliaries, the correct form of 'do' is used (He came to see me, didn't he?)

Answer: (b)

Options (a), (c) and (d) will distort the meaning. The clue is 'great role' which obviously means that help has been given, so (b) is clearly the correct answer response.
