Select the most appropriate option to fill in the blank.
The agility of the acrobat ______ and thrilled the audience.

Correct option is D

The word that can be filled in the blank is 'amazed' to make the sentence grammatically and contextually correct.
Explanation:
1. Subject-Verb Agreement:
· The subject "The agility of the acrobat" is singular, so the verb must agree with it.
· The sentence is in the past tense, as indicated by "thrilled," so we need a verb in the past tense as well.
2. Correct usage of "amazed":
· "Amazed" is the correct verb in the past tense, which maintains parallelism with "thrilled" (both actions happened in the past).
· Correct sentence: "The agility of the acrobat amazed and thrilled the audience."
Why other options are incorrect?
· (a) Amaze – Incorrect because "amaze" is in the present tense and does not match "thrilled" (past tense).
· (b) Amazes – Incorrect because "amazes" is present tense, while "thrilled" is in the past.
· (c) Amazing – Incorrect because "amazing" is an adjective or present participle, which does not fit grammatically in this sentence.
Conclusion:
Since "amazed" correctly matches the past tense and maintains proper sentence structure, option (d) "amazed" is the correct answer. ✅
