At Food World Supermarket, Built In 1975, The Number Of Successful Thefts GMAT Critical Reasoning

Question: At Food World Supermarket, built in 1975, the number of successful thefts has risen dramatically in the last few months. Food world has a reliable electronic security system at all the customer exit doors, and this system is always operational. Therefore the thefts must have been committed by people who used exits other than the regular customer exit doors.

Which of the following is an assumption that would make the conclusion above logically correct?

(A) If a surveillance system is installed in a supermarket, it is always equipped at every possible exit.
(B) If an employee wishes, he is allowed to leave through an exit that is not monitored by a surveillance system.
(C) If a store has a reliable security system, it is impossible to pass through the system undetected.
(D) If a supermarket was built before 1980, it often has exits that cannot be equipped with electronic surveillance.
(E) If a store has a reliable electronic security system but is still experiencing a rise in theft, it must be the case that the employees must be stealing.

Explanation

(A) If a surveillance system is installed in a supermarket, it is always equipped at every possible exit. The given statement is incorrect because it only says that thefts can exit the supermarkets where there is no surveillance system. It contradicts its argument because it was discussed in the argument that every supermarket has an installed system at its exit door.

(B) If an employee wishes, he is allowed to leave through an exit that is not monitored by a surveillance system. The given statement is incorrect because according to this statement, it is already assumed that when employees exit, there is no controlled surveillance system. But as per the given argument, food world has a reliable electronic security system at all the customer exit doors, and this system is always operational. Therefore, the given statement is irrelevant.

(C) If a store has a reliable security system, it is impossible to pass through the system undetected. The given statement is correct because there is a reliable electronic security system at all the customer exit doors. Through this surveillance system, no person (either thefts or customers) can pass undetected.

(D) If a supermarket was built before 1980, it often has exits that cannot be equipped with electronic surveillance. The given statement is incorrect because it is already said that the food world has some exits without or with security exit. So, it is of no use whether they are equipped with an “electronic system” or not. Therefore, this statement is considered irrelevant.

(E) If a store has a reliable electronic security system but is still experiencing a rise in theft, it must be the case that the employees must be stealing. The given statement is incorrect because everyone present in the supermarket or store has to pass through the electronic exit system. So. no people can remain undetected in this case.
