Question

Complete the following sentence :
I will not go to his party __________ he invites me.

• A. until
• B. if
• C. unless
• D. but

Hint:

Remember that "unless" introduces the only condition that can prevent the main clause from being true. It is equivalent to "if...not". For example, "You will fail unless you study" means "You will fail if you do not study."

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
This question tests the correct usage of conjunctions to express a condition. The sentence structure requires a word that means "except if".
Step 2: Detailed Explanation:
Let's analyze the options:
- until: Implies a time condition. "I will not go until he invites me" means I will wait for his invitation and then go. This changes the meaning.
- if: "I will not go if he invites me." This is grammatically correct but means the invitation is the reason for not going, which is an unusual sentiment.
- unless: Means "if not" or "except on the condition that". "I will not go to his party unless he invites me" means the only condition under which I will go is if he invites me. This fits the context perfectly.
- but: Is a coordinating conjunction used to connect contrasting ideas, which doesn't fit here.
Step 3: Final Answer:
The most logical and grammatically correct conjunction for this sentence is "unless". Therefore, the correct option is (C).
