Have you read what goes with this question?
Answer:
D. Most infants died before childhood.
Explanation:
Unfortunately, most children fell to disease and harsh conditions. Back then medicine was not evolved as it is now and most would die of the common cold. But it was also customary to have large families in order to support the family so kids often were used as labor and died in unfortunate accidents or from exhaustion. Today, there are many many laws protecting children from such things and medicine has evolved so most people in wealthy countries could live up to 70 years old if they take care of themselves.
Answer: This question does not give me enough information to answer it.
I think the bolded words would be "whom Mr. Stein chose". The clause whom Mr. Stein chose is an example of an adjective because the clause describes the word student. Student is the subject of the sentence and is a noun. An adjective describes a noun or another subject. an adverb describes a verb or another adverb.
