A greater number of cars are sold in Town P than in Town Q. Therefore, the citizens of Town P spend more time driving their cars, per capita, than do the citizens of Town Q.
Each of the following, if true, weakens the conclusion above EXCEPT:
A. Town P has a larger population than Town Q.
B. Most citizens of Town Q work in Town P and buy their cars there.
C. Many residents of Town P purchase second cars that they use only rarely.
D. Most drivers from Town P tend to drive only during the day, and only within the city limits of Town P.
E. The average price of cars sold in Town P is lower than the average price of cars sold in Town Q.
OA after some discussion.

Question:
No. of cars in P > No. of cars in Q => Per capita car usage in P > in Q.
Possible weakners before I went to answer choices
1. Not all cars that are purchased in P are used.
2. Most of people from Q purchase cars in Q.
Going to options:
A. Here the word per capita helps evaluating this one. So, this weakens our arguments.
B. My guess 2 works here.
C. My guess 1 fits here.
D. Here, I think, we can assume that per capita usage is done during day time and within city limits of P. However, there could be a chance that most of cars from Q are driven during night and outside borders of Q. Thus, it weakens too.
E. Here the argument does not mention any relation between demand and supply of cars. Thus, I think that price factor cannot be used to evaluate the argument.
Thus, IMO E.
However, I would love to hear more on D vs E.

Conclusion - per capita car uses at P > q
Eliminate answers which raises doubts on this conclusion.
D - Limits care uses to during day time and within city limits for P. Uses in city Q may be more if it does not have such limits. It weakens so RULED OUT.
E - Price has no correlation with car uses. CORRECT.

The argument links the NUMBER OF CARS SOLD IN P to the NUMBER OF HOURS DRIVEN IN P.binit wrote:A greater number of cars are sold in Town P than in Town Q. Therefore, the citizens of Town P spend more time driving their cars, per capita, than do the citizens of Town Q.
Each of the following, if true, weakens the conclusion above EXCEPT:
The assumption is that most of the cars SOLD in P are actually DRIVEN in P.
Eliminate the four answer choices that DO weaken the conclusion.
A. Town P has a larger population than Town Q.
Here, P could have more citizens per car -- perhaps 100 citizens for every car -- implying that most of the citizens in P do not own a car.
Thus, the conclusion that citizens in P spend more time driving is weakened.
Eliminate A.
B. Most citizens of Town Q work in Town P and buy their cars there.
Here, many of the cars sold in P belong to citizens in Q, implying that many of the cars sold in P are not driven by P's citizens.
Thus, the conclusion that citizens in P spend more time driving is weakened.
Eliminate B.
C. Many residents of Town P purchase second cars that they use only rarely.
Here, many of the cars sold in P are rarely used.
Thus, the conclusion that citizens in P spend more time driving is weakened.
Eliminate C.
D. Most drivers from Town P tend to drive only during the day, and only within the city limits of Town P.
Here, many of the cars sold in P are used for a limited number of hours (only during the day) to travel limited distances (only within the city limits).
Thus, the conclusion that citizens in P spend more time driving is weakened.
Eliminate D.
The correct answer is E.
E. The average price of cars sold in Town P is lower than the average price of cars sold in Town Q.
The price of the cars sold in P tells us nothing about how often these cars are driven.

Hi Mitch, town P has more population than town Q - means town P has more citizens, right?A. Town P has a larger population than Town Q.
Here, P has more cars but fewer citizens -- P could have 100 cars but only 2 citizens -- implying that most of the cars in P are rarely on the road.
Thus, the conclusion that citizens in P spend more time driving is weakened.
Eliminate A.
I eliminated this choice, since more citizens minimize the per capita driving (population comes in denominator)
Anyway the OA is E. Thanks everybody.

My post above should have read more citizens per car.
I've edited it accordingly.
