Question

Fill in the blank with the appropriate verb tense:
Study well lest you _______ fail.

• A. should
• B. should not
• C. should have
• D. None of the above

Answer 1

The correct option is A should

Option A is correct. The conjunction lest means "for fear that" or "in order to avoid". It is followed by something the speaker or subject thinks should be avoided. Thus, should is the right answer since failing is something that needs to be avoided.

Options B and C are incorrect since it implies that the intention is to fail, rather than avoid it.

Option D is incorrect since the right answer is option A.
