City official: In order to revitalize our city’s downtown business district, we should increase the number of police officers that patrol the district during business hours. Three years ago, the city reduced the total size of its police force by nearly 20 percent. Since then, retail businesses in the district have experienced a steady decline in revenue.

Any of the following, if true, would be an effective criticism of the city official’s recommendation EXCEPT:

A. Two years ago, the city established more rigorous standards for the retention and hiring of its police officers.
B. New businesses offering products or services similar to those in the district have emerged outside the district recently.
C. The number of people who reside in the district has not changed significantly over the last three years.
D. Businesses operating in the city but outside the district have experienced declining revenues during the last three years.
E. Some of the city’s police officers patrol areas outside as well as inside the district.
OA : C
Please explain how C is the answer

Conclusion: Revitalize business district ->increase No.of police
Premise: 20% reduce police -> decrease business revenue
Question: All weaken conclusion EXCEPT
(A) Two years ago, the city established more rigorous standards for the retention and hiring of its police officers. ->Explain the reason for 20% reduction of police official
(B) New businesses offering products or services similar to those in the district have emerged outside the district recently. -> Reason for decrease of district business revenue
(C) The number of people who reside in the district has not changed significantly over the last three years. -> Doesn't have any impact on Conclusion or Premise
(D) Businesses operating in the city but outside the district have experienced declining revenues during the last three years.-> Revenue reduction is a common phenomenal, not because of police official reduction.
(E) Some of the city’s police officers patrol areas outside as well as inside the district. -> So why only district business revenue went down why the police officers also patrol outside the district. Therefore, that revenue of biz in district went down dues to other reasons.

First I came up with A & C. Because A attacked the premise not the conclusion. But C doesn't help anything for conclusion or premise, I choose C as my final answer.

Option A only tells us the reason for which the number of police has been reduced

This is not a good question. Is it really from Princeton Review? B is the only weakener, as it attacks the author's underlying assumption--that the reduction in the police force actually caused the decline in revenue. If someone rewrote this as a non-EXCEPT q with B as the answer, I guess it would be okay.

A is irrelevant. We don't care why the number of officers declined. We care why sales declined. Besides, this change happened after the reduction in the police force.
C strengthens the argument by ruling out a potential alternative cause.
D doesn't help us to assess whether the reduction in the police force caused the decline. Since the reduction in police was city-wide, it could have been the cause of retail declines throughout the city. If anything, this could be seen as a strengthener.
E is irrelevant. We don't need to know what the officers do all week long. We just need to know whether the reduction affected the decline, and this doesn't do anything to suggest that it didn't.
