A major barrier to the widespread acceptance of electric vehicles by people who use their cars almost exclusively for commuting is the long time it takes to recharge the battery. However, the relatively long time it takes to recharge can easily be fitted into the regular patterns of car use characteristic of many commuters. Therefore, only those who also use their cars for occasional extended trips cannot replace a conventional car with an electric vehicle.
Which of the following statements, if true, most seriously weakens the argument above?
(A) Many electric vehicles that are used for commercial purposes are not needed for extended trips.
(B) Because a majority of commuters drive more than 50 miles a day, many electric vehicles need to recharge more than once a day to ensure that commuters will not run out of electricity while sitting in traffic.
(C) One producer of electric vehicles has a customer service plan that allows its customers to use a conventional car for three days for every 1000 miles they drive their electric vehicles.
(D) Despite the fact that running electric vehicles produce virtually no environmentally harmful emissions, generating electricity to recharge an electric vehicles battery produces significant environmental damage.
(E) Some family vehicles are used for making many short local trips rather than for commuting.
Question Type: Weaken Conclusion.
Argument Conclusion: One cannot replace those conventional cars that are needed for the extended trip with electric cars.
My AC is A.
A. Cannot boot this AC so will keep it.
B. If anything this strengthen the author's argument. Boot out
C. Irrelevant but will keep AC because not 100% sure.
D. Out of Scope. Boot out.
E. So what. Doesnt weaken conclusion. Boot out.
Between A and D, A weakens the author's conclusion because if many eletric vehicles used for commercial purposes arent needed for extended trips then we will never reach the criteria that the author discusses [requiring eletric cars for the long trips] and therefore cannot be replaced, according to the author.
