The Correct Answer and Explanation is :

Here are the correct answers to your sentences along with explanations:

1. Only a credulous person could believe her tale.
2. He effected a complete change in the appearance of the compound by cooling it.
3. All except she have chosen their research topics for next year.

Explanations:

1. Credulous vs. Credible:

• Credulous means willing to believe or trust too easily, often without sufficient evidence. In the context of the sentence, it implies that only someone who is easily fooled or overly trusting would accept the tale as true.
• Credible, on the other hand, means believable or convincing. It describes something that is worthy of belief but does not imply the same level of naivety as “credulous.” In this context, “credulous” is the appropriate choice because it highlights the uncritical acceptance of an implausible story.

1. Effected vs. Affected:

• Effected means to cause something to happen; it refers to the actual implementation or achievement of a change. In the sentence, it indicates that the act of cooling led to a tangible change in the compound’s appearance.
• Affected, however, typically means to have an influence on something or someone, indicating a change in condition or state but not necessarily bringing about a specific change. Since the sentence indicates a change that was brought about through action (cooling), “effected” is the correct term.

1. She vs. Her:

• In this sentence, “All except she have chosen their research topics” is correct because “she” is the subject of the implied verb “have.” When the verb is in the form of “have chosen,” it refers to the people (including “she”) who have made a choice.
• If “her” were used, it would suggest that “her” is the object, which would not fit the grammatical structure of this sentence. The sentence is structured to imply that everyone else, besides “she,” has made their topic choices.

In summary, understanding the distinctions between these words and their grammatical roles in a sentence is essential for clear and effective communication.
