why c?

A car's antitheft alarm tat sounds in the middle of the night in a crowded city neighborhood may stop an attempted car theft. On the other hand, the alarm might signal only a fault in the device, or a response to some harmless contact, such as a tree branch brushing the car. But whatever the cause, the sleep of many people in the neighborhood is disturbed. Out of consideration for others, people who have these antitheft alarms on their cars should deactivate them when they park in crowded city neighborhoods at night.
Which one of the following, if assumed by the author of the passage, would allow her properly to draw her conclusion that the owners of alarm-equipped cars should deactivate the alarms when parking in crowded city neighborhoods at night?
(A) The inconvenience of false alarms is small price to pay for the security of a neighborhood.
(B) In most cases when a car alarm sounds at night, it is a false alarm.
(C) Allowing the residents of a crowded city neighborhood to sleep undisturbed is more important than preventing car theft.
(D) People who equip their cars with antitheft alarms are generally inconsiderate of others.
(E) The sounding of car antitheft alarms during the daytime does not disturb the residents of crowded city neighborhoods.

IMO

A: can be eliminated as OOS. Security of neighborhood is out of scope.
B: is too extreme and not implied.
D: is too extreme.
E: is out of scope. What happens in day is not of concern.

This leaves C as the contender

Surprise, surprise another LSAT question. This one is from the February 1995 test, 2nd LR section, number 23.

This type of question is something that is not actually on the GMAT. It may seem like a strengthen question, but it is a different type of strengthen, a strengthen where the conclusion is PROVEN to be true, not just strengthened.

You can normally treat these questions just as you would a strengthen question, but sometimes you get a strange one. Here is a rule of thumb for using LSAT strengthen questions:

1) If want a normal strengthen type of question look for the word "most" in the question stem. All normal strengthen questions have the word most. (Of course this word appears in many other types of questions such as inference and weaken but the word "most" never appears in assumption questions on the LSAT and never in this type of question here where the conclusion is proven true).

2) If you are looking for assumption questions on the LSAT to try, look for the argument to make the assumption. Ask yourself, is it the argument that is assuming? For example, if the question stem says, "Which of the following, if assumed, most strengthens the argument?" This is not an assumption! You can see that the argument is not making the assumption. By contrast, "The argument relies on which of the following assumptions?" is an assumption question.


Anyway, to this question...we are looking to prove the conclusion. Please note that the conclusion is repeated in the question stem, it is "that the owners of alarm-equipped cars should deactivate the alarms when parking in crowded city neighborhoods at night." We want something that will Prove this conclusion. So how do we prove it? Well the stimulus says that "whatever the cause (of the alarm), the sleep of many people in the neighborhood is disturbed."

So we need the fact that sleep is disturbed to mean that people SHOULD deactivate their alarms. This is what choice C goes to. It says, "Allowing the residents of a crowded city neighborhood to sleep undisturbed is more important than preventing car theft." If the alarms disturb sleep, it does not matter if they also prevent theft. We are told that sleep is more important.

B would strengthen but it does not Prove that people should shut off the alarms.

Hope it helps!
