36. Which sentence is grammatically correct?
Answer: C
Mona performed badly during dance class.
Mona performed badly during dance class is the grammatically correct sentence, as it uses the adverb "badly" to modify the verb "performed."
A) Sam behaved bad during Mr. Johnson's lecture.
This sentence is incorrect because it uses "bad" as an adjective instead of the appropriate adverb "badly" to modify the verb "behaved." In standard English, adverbs are required to modify verbs.
B) Joe limped bad after his collision in gym class.
Similar to option A, this sentence incorrectly uses "bad" instead of the adverb "badly." The correct form should be "Joe limped badly" to accurately describe the manner in which he limped.
C) Mona performed badly during dance class.
This option is correct, as it properly uses the adverb "badly" to describe how Mona performed in dance class. Adverbs are used to modify verbs, which makes this sentence grammatically accurate.
D) The chemistry lab after third period smells badly.
This sentence is incorrect because it uses "badly" when it should use the adjective "bad" to describe the noun "lab." The correct form would be "The chemistry lab smells bad," as the verb "smells" is linking the subject to a state of being.
Conclusion
The correct answer, "Mona performed badly during dance class," illustrates the proper use of an adverb to modify a verb. Options A, B, and D incorrectly use adjectives in contexts where adverbs are required, while option C adheres to grammatical rules, making it the only correct choice.
