25. Select the grammatically correct sentence.

Answer: A

Explanation:

The students looked at their test scores.

This sentence is grammatically correct as it properly uses the plural noun "students" with the appropriate verb "looked" and correctly indicates possession with "their."

A) The students looked at their test scores.

This option is correct because it follows standard English grammar rules. It includes a subject ("The students"), a verb ("looked"), and a prepositional phrase ("at their test scores") that completes the thought clearly and accurately.

B) Their comes a time when one must choose between right and wrong.

This option is incorrect due to the misuse of "Their" at the beginning of the sentence. The correct word should be "There," which indicates a time or place, rather than possession.

C) Their waiting for you.

This option is incorrect because "Their" is improperly used. The correct word should be "They're," a contraction for "they are," which fits the context of someone waiting.

D) The patient told the nurse, 'Put the flowers on that table over their.'

This option is incorrect because "their" is used inappropriately. The correct word should be "there," which refers to a location, while "their" indicates possession.

Conclusion

The correct answer, A, is the only option that adheres to grammatical conventions and conveys a clear meaning. The other options either misuse possessive forms or incorrect word choices, leading to confusion and grammatical errors. Thus, option A stands out as the only properly constructed sentence.
