Correct Answer: A. by

Explanation

The most appropriate preposition to use here is A. by.

Disappointed by is used to indicate the cause or reason for the disappointment. In this sentence, the ways you conducted yourself are the cause of the speaker's disappointment.

• I am disappointed by the ways you conducted yourself at the party.

While disappointed at can sometimes be used for specific events or behaviors, disappointed by more strongly emphasizes the source or cause of the feeling, which fits perfectly here. Disappointed in or disappointed with would also be common, but they aren't options here.

Correct Answer: D. an iamb

Correct Answer: B. supremacy of the law

Correct Answer: D. as if

Explanation

The sentence He acts ..... he were a manager describes how someone behaves, suggesting a hypothetical or unreal situation.

Let's look at the options:

• A. like: While like is sometimes used informally as a conjunction (e.g., He acts like he owns the place), in formal English, and especially when introducing a clause with a subject and verb expressing a hypothetical situation, it's generally less preferred than as if or as though.

• B. such as: Such as is used to introduce examples (e.g., He enjoys sports such as football and basketball). It does not fit the context of expressing a manner or hypothetical situation.

• C. such: Such is used as a determiner or pronoun (e.g., He is such a nice person or I've never seen such a thing). It cannot function as a conjunction here.

• D. as if: As if is a conjunction that means in a way that suggests or as it would be if. It is perfectly suited for introducing a clause that describes a hypothetical or imagined situation, often followed by the subjunctive mood (like were).

The phrase he were a manager uses the subjunctive mood, indicating that he is *not* actually a manager but acts in a way that *suggests* he is. As if is the correct and best conjunction to introduce this type of clause.

Therefore, the best completion is:

He acts as if he were a manager.

The final answer is D
