Difficulty—

Each bank in the town of La Rinconada has only a single set of locking doors at its entrance. In the town of Inverness, on the other hand, the entrances to nearly all banks are equipped with two sets of locking doors, operated by a mechanism that allows only one set of doors to be open at a time. It is clear, then, that banks in Inverness experience more robbery attempts than do those in La Rinconada, and have thus adopted the extra doors as a security measure.

Which of the following, if true, most weakens the argument above?

(A) Last year the number of bank robberies in La Rinconada was almost one-half greater than the corresponding figure for the previous year.

(B) Inverness is known for its harsh winters, while the climate of La Rinconada is quite temperate year-round.

(C) The mechanism of the double doors used by banks in Inverness allows bank security personnel to lock the doors remotely.

(D) Bank robbery attempts are typically unsuccessful, and, even when the robbers do manage to escape with stolen money, the sum is usually quite small.

(E) Inverness has almost twice as many police officers per capita as does La Rinconada.

Before answering this question or checking the answer choices, consider: What would weaken the argument.

Premise: Banks in Inverness experience more robbery attempts than those in La Rinconada.

Conclusion: Banks in Inverness, therefore, have adopted extra doors as a security measure.

Now, if the adoption of extra doors as a security measure by Banks in Inverness was caused by other factors not related to robberies or security, then this argument would be weakened.

Option A - Incorrect
The answer choice does not weaken the argument because the argument was not concerned about the comparison of bank robberies in La Rinconada. Hence, it's concerned about if the adoption of extra doors as a security measure by Banks in Inverness was caused by robberies or not.

Option B - Correct
This claim gives us a possible explanation of why Banks in Inverness adopted extra doors as a security measure.

Option C - Incorrect
This answer choice provides evidence that most strengthens the argument rather than it weakens it.

Option D - Incorrect
This option fails to take into account that the reason why Banks in Inverness adopted extra doors as a security measure according to the passage was that they experienced more robberies.

Option E - Incorrect
This claim literarily counters the idea of the protective measure incorporated by the Banks because, Inverness, having many police forces should strengthen the city security forces. In addition, comparing the number of police officers in Inverness to La Rinconada is not the subject matter of this discussion. So, therefore, this answer choice is wrong.
