Kaplan Gmat Verbal workout Section 3
3.At Food World Supermarket, built in 1975, the number of successful thefts has risen dramatically in the past few months. Food World has a reliable electronic security system at all customer exit doors, and this system is always in operation.
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 so wishes, he is allowed to leave through an exit that is not monitored by surveillance equipment.
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 are stealing.
Who may help to explain why B is wrong and why C is correct?
"Therefore, the thefts must have been committed by people who used exits other than the regular customer exit doors" means that the theft would be caught at non-customers exit?
what is the different between" exits "and"regular customer exit door" ? are they the same exits?
the correct answer is C.
Thanks
