Choose the most suitable option to replace the highlighted part of the sentence:
He worked very hard lest he may fail.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. lest he should fail.
Context: The sentence shows a purpose with fear that he might fail.
Grammatical concept: After “lest”, we use “should + base verb”. We do not use “may” with “lest”.
Analysis of the given options:
- in order that he does not fail – Incorrect; changes the structure and meaning.
- for not failing – Incorrect; not suitable in this sentence.
- lest he should fail – Correct; follows the correct rule of “lest + should”.
- so that he did not fail – Incorrect; wrong tense and meaning.
Correct word/ phrase: lest he should fail
Final sentence: He worked very hard lest he should fail.
Hence, the chosen option is correct.
