Question

Choose the correct adverb from the options given.
Are you _______ sure I can't help you?

• A. Rather
• B. Too
• C. So
• D. Quite

Answer 1

The correct option is D Quite

In order to fill in the blank, let's understand what degree of adverbs and quantity are. The degree of adverbs explains 'to what extent' and the quantity explains us 'how much.'

Option A - 'Rather' is an adverb, which is used to indicate negativity about the noun/subject, adjective or the adverb in a sentence. For example, 'She is behaving rather strangely.' It means the same as 'quite', and 'to a certain extent.' As the sentence doesn't indicate negativity, we can't use 'rather' here. Hence, option A is incorrect.

Option B - 'Too' is an adverb, which means 'at a higher degree' or 'in addition to'. It is often used to indicate negativity about the noun/subject, adjective or the adverb. For example, 'She was driving too fast.' and 'She is beautiful and kind too.' As the sentence doesn't indicate both the meanings of 'too', we can't use it here. Hence, option B is incorrect.

Option C - 'So' is an adverb, which means 'to such an extent, that...' or 'in comparison'. For example, 'I am so happy today that I am going to give you a treat.' or 'He isn't so great as you'd think.' 'So' is often used in a sentence that has two clauses. Hence, option C is incorrect.

Option D - 'Quite' is an adverb, which means 'completely' It is used in a sentence to indicate a positive action, adjective or noun. As the given sentence is positive, we can use 'quite'. Hence, option D is the correct answer.
