Question

Fill in the blank using a suitable option.
Work hard, lest you ____ fail.
A. May
B. Can
C. Should
D. Would

Answer 1

Hint:The given sentence suggests that working hard is necessary to avert failure. The word ‘lest’ is a clause expressing fear demanding a precautionary action. Therefore, the meaning of the sentence is that one shall work hard to avoid failure. We will look for an option that expresses a strong assertion.

Complete answer:
Let us analyse each option individually in detail to figure out the correct option with the help of the above stated hint.

May : The modal verb may is used to express possibility or permission . Something that is not guaranteed or sure. Example: May I ask you a question? This is not the required verb here. Therefore, this is not the correct option.

Can: The modal verb ‘can’ is used to express capability and permission. Example: I can play the piano. This is not the intended option.

Should : The modal verb ‘should’ is the past tense of ‘shall’ which expresses strong intent and assertion. Therefore, this is the correct option.

Would : The modal verb ‘would’ is the past tense of ‘will’ which expresses certainty. This sentence doesn’t require an emphasis of certainty. Therefore, this is not the correct option.

Hence, the correct answer is option ‘C’.

Note:The given sentence means that if we work hard , there is a good chance that we might not fail. But, it is not certain. Therefore, we have concluded our answer which expresses a strong assertion but not certainty.
