Question

Choose an appropriate conjunction to complete the sentence:

A lot of people would be out of work _____ the factory closed down.

• A. when
• B. if
• C. while
• D. as

Answer 1

The correct option is B if

Subordinating conjunction 'if' is used when one clause of a sentence is dependent upon the other clause being possible; ie. an action is possible in case of the first action occurring. Here, the main clause indicates the first action - factory being closed - will lead to the dependent action - many people being out of work. Therefore the correct option is: if.
