Question

Complete the sentence appropriately : ____ you answer all of my questions. I can't do anything to help you.
1. If
2. Unless
3. Whenever

Answer 1

2. Unless

Unless you answer all of my questions, I can't do anything to help you.

Explanation:

• The best choice for our answer is 'Unless' because the speaker would not be able to help the listener if the questions are not answered.

• The meaning of the word 'Unless' is 'except if' or 'if not'. So if we want to understand that sentence in a proper way, we may think as: If you do not answer all of my questions, I can't do anything to help you.

• However 'Unless' is used here as a Conjunction (whose work is to join two or more words or sentences).
