33. Which sentence is grammatically correct?

Answer: C

Explanation:

Sarah plays her new saxophone well.

This sentence is grammatically correct as it clearly conveys that Sarah is proficient in playing her new saxophone.

A) The dog catches the Frisbee well.

This sentence is incorrect because the phrase "catches the Frisbee well" implies a sense of proficiency, but the overall context may lack clarity regarding the dog’s ability in catching. The focus is not as strong as in the correct answer.

B) The band did well during the halftime show.

While this sentence is grammatically correct, it does not emphasize the proficiency of an individual in a skill, which is central to the answer being evaluated. The sentence is more about the band's overall performance rather than a specific skill.

C) Sarah plays her new saxophone well.

This is the correct answer as it uses the adverb "well" to describe how Sarah plays, indicating her level of skill with the saxophone. It effectively highlights her ability in a specific context.

D) The band that played before ours was good.

This sentence is grammatically correct but focuses on the quality of the band rather than the proficiency of an individual's skill. It does not align with the question's requirement to identify a sentence that demonstrates an individual's ability.

Conclusion

The correct answer, "Sarah plays her new saxophone well," is definitive as it accurately presents an individual's skill in a clear and grammatically correct manner. All other options, while grammatically correct in their own right, do not specifically address an individual's proficiency in a skill, which is the core concept being tested.
