Question

Fill in the blank by choosing the most appropriate option:
We shall fail _________ we are industrious.

• A. Until
• B. Whether
• C. Unless
• D. Though

Answer 1

The correct option is C Unless

Option C: 'Unless' means 'except if'. In the given sentence, it means 'we shall fail except if we are industrious', or 'we shall fail if we are not industrious'. If we're industrious, we won't fail.

Hence this word forms a meaningful sentence and option C is correct.

Option A: 'Until' means 'up to a point in time'.

Option B: 'Whether' expresses a doubt or choice between alternatives.

Option D: 'Though' means 'despite the fact that'.

These words do not form complete meaningful sentences. Hence options A, B and D are wrong.
