One theme in The Strange Case of Dr. Jekyll and Mr.
Hyde is the message "Evil can never truly hide itself."
Which event best connects to this theme?
Mr. Enfield and Mr. Utterson see Dr. Jekyll while they are
walking.
An axe is used to break down the door into the doctor's
laboratory.
Mr. Hyde's dead body is found in Dr. Jekyll's laboratory.
Mr. Utterson takes documents home to read and
understand.

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.

the answer is:

to persuade readers that a conquering prince must destroy a former republic if he hopes to hold it.

in the excerpt from "the prince," the author niccolò machiavelli suggests that to take possession of a city and endure the control over it, it is necessary to destroy it first. otherwise, people who have known freedom will eventually turn against the new rulers and fight back to recover their power.
