Answer:
I finished my research paper two days early.
Explanation:
The passive means that something is being done to the subject. Since in the first two sentences the subject is research paper, and something is being done to them passively, these first sentences are passive. However, in the third, “I” is the subject, and “I” is doing something to the research paper, which, in this sentence, is the predicate. Since the subject is actively doing something to the predicate, this sentence is active.
i think its either A, or D. but im not sure
Expositions usually go into great depth and detail about a certain subject and can provide more information than just a casual reading about a topic. They are essential for any expert.
