Which of the following most logically completes the argument below?
In recent years,the proportion of car buyers who buy new cars rather than used cars has declined.Some consumers have attributed this change to an increase in new-car prices.As evidence of the price increase,they cite figures that show that,even adjusting for inflation,the price that the buyer of a new car pays,on average,is far higher now than a few year ago.
This evidence is unpersuasive,however,because___________
a) the value of a car the is bought new declines much more rapidly than does the value of a car that is bought used ----value doesnt say anything related to the argument about price--irrelevant
b) after someone has bought a car, it might be several years before that person next buys a car--irrelevant
c) a decline in the proportion of car buyers who buy new cars must necessarily mean that the proportion who buy used car has increased---just say what argument say ,no function--irrelevent
d) the relative increase in used-car sales might be explained by the decisions  of only a small proportion of all car buyers---
even if  it is only a samll proportion,price may also be a factor for buyers to buy a car,so it doesnt do anything to argument
e) the change in the average price paid for a new car could result solely from more people's rejecting inexpensive new cars in favor of used cars.
--as i guess ,this is correct answer.arument say price change led to more buy used cars rather than new ones.
here answer say buy used cars rather than new cars led to price change. a way to weaken argument :exchange the premise and conclusion.
if answer is not e ,then i my analysis is wrong.
