Fill in the blank with the word or phrase that makes the text below grammatically correct.

The retired government official spoke_______ about foreign policy and international trade.

Rationale

knowledgeably

The adverb "knowledgeably" appropriately modifies the verb "spoke," indicating that the retired government official spoke with a high level of understanding regarding foreign policy and international trade.

A (as knowing) YOUR ANSWER

This phrase is grammatically incorrect in this context. "As knowing" does not function as an adverb and fails to provide the necessary modification of the verb "spoke." Instead, it suggests a comparative structure that does not fit the sentence's requirement.

B (in knowledge) YOUR ANSWER

While "in knowledge" might seem relevant, it does not serve as an adverb either. This phrase implies a state of being rather than the manner of speaking, hence it does not convey how the official spoke about the topics discussed.

D (knowledgeable) YOUR ANSWER

Although "knowledgeable" correctly describes someone who possesses knowledge, it is an adjective and does not appropriately modify the verb "spoke." The sentence requires an adverb to describe the action of speaking, making this choice unsuitable.

Conclusion

In this context, the correct choice is "knowledgeably," as it effectively modifies the verb "spoke" and conveys the manner in which the retired government official discussed foreign policy and international trade. The other options fail to provide the necessary grammatical structure or meaning, demonstrating the importance of using the correct part of speech to achieve clarity and precision in language.
