Question 23

The retired government official spoke knowledgeably about foreign policy and international trade.

Using the adverb "knowledgeably" correctly modifies the verb "spoke," indicating how the retired government official communicated about foreign policy and international trade.

A) as knowing

This option is incorrect because "as knowing" does not function as an appropriate adverb in this context. It fails to modify the verb "spoke" properly and does not convey the intended meaning of the sentence.

B) in knowledge

This choice is also incorrect since "in knowledge" does not serve as an adverb. It awkwardly suggests a state rather than an action, making it unsuitable for describing how the official spoke.

C) knowledgeably

This option is correct as "knowledgeably" is an adverb that effectively describes the manner in which the retired government official spoke. It indicates that the official communicated with a good understanding of the subject matter.

D) knowledgeable

While "knowledgeable" is an appropriate adjective, it cannot be used in this sentence to modify the verb "spoke." It would require a different sentence structure to fit correctly, making it an unsuitable choice in this context.

Conclusion

The correct answer, "knowledgeably," clearly modifies the verb in the sentence, accurately conveying the manner of the official's speech. The other options either fail to function grammatically or do not appropriately modify the verb, highlighting why they are incorrect.
