Improve the underlined part of the sentence. Choose ‘No improvement’ as an answer if the sentence is grammatically correct.

A man may die, nations may rise and fall, but an idea lived on.

"The correct answer is option 4, "lives on."

Key Points

• The verb "live" needs to agree with the subject "an idea," which is singular. Also, the given sentence is a general truth.
• Thus, it will be expressed in simple present tense.
• Therefore, the correct form of the verb is "lives."
• However, the sentence also requires a preposition to show how the idea continues to exist.
• The correct preposition in this case is "on," which means "to continue to exist or be active."
• Therefore, the correct phrase is "lives on."
• Option 1, "lives in," is incorrect because it does not convey the same meaning as the original sentence.
• Option 2, "live on," is grammatically incorrect because it is missing the necessary subject-verb agreement.
• Option 3, "No improvement," is incorrect.

Correct Sentence: A man may die, nations may rise and fall, but an idea lives on.
