I think that you would have to add commas in each of the sentences, is they how they are written? Did you take the punctuation out?
Answer:
Mr. Hooper had ascended the stairs, and showed himself in the pulpit, face to face with his congregation, except for the black veil. That mysterious emblem was never once withdrawn. ... The veil represents some evil deed hidden in the minister's past that he is afraid to make public.
The answer is "I went to one class to another all day." It is using language literally as that person actually did go from one class to another, while in the other sentences, figurative language (IE exaggerated or personified language) is used to express the author's point.
The answer to #4 is "By" because a preposition word is a word that procedes to a noun or a pronoun. Some examples are "after", "against", "before", "behind", "below", ect... In this case the preposition is "by" and it procedes to the words "royal proclamanation"
