electric-powered cars

by sumanr84 » Sun Jun 27, 2010 10:17 am
Over the last five years, technological improvements have significantly reduced the cost of manufacturing and operating electric-powered cars. Nevertheless, the cost per gallon of gasoline at which it would become more economical to operate an electric car than a regular gas-powered car has remained unchanged.

Which of the following, if true, would do the most to explain why electric cars have become cheaper to operate but break-even point between electric and gas cars has not changed?

a. The price per gallon of gasoline has dropped by 25% over the last five years.
b. Electric-car manufacturers have managed to reduce production costs despite an increase in some raw material prices.
c. Improvements in aerodynamics have made regular gas-powered cars more efficient to operate.
d. Relative to the number of gas-powered cars, there are very few electric cars on the road today.
e. When the price of gasoline rises, more people are willing to take public transportation to work.

I pick A.

Electric cars have become cheaper to operate but break-even point between electric and gas cars has not changed. One of the possible reason could be that even gas powered cars have become cheaper to operate.

Option A points out that the price per gallon of gasoline has dropped by 25% over the last five years. If this is true, then gas powered cars should have also become cheaper to operate.

Post the OA along with the question, buddy. We have wait till couple days to know whether our reasoning was right. In many cases, we even forget to keep track of the thread. Just a request.

i dont understand the second part of the question
does it require us to find some reasons to explain why electric cares have become cheaper to operate but manufacturers still should not produce electric car?
if im right i will choose B for my answer

Seems A .

B, C and E seem far away from the answer.

D talks about the overall picture whereas we need to find why after all the advancement electric cars are not cheaper to operate than are gas cars. Because the operating cost of gas cars has itself been reducing for the last 5 yrs.

OA : C

My takeaway from this :
Be extremely careful with too obvious looking answer. ' A 'is such an option that comes as a blinder to anyone and there lies the catch.

To all those who just missed the OA like me,.. please give it a one more shot to get to the OE.

IMO this argument states that the electric car consume more gasoline than regular car(Since its consume more gasoline than the rate that is economical,the cost is high)

So whatever the gasoline price,the electric car consume more gasoline and the cost will be higher than regular cars.

What make electric car consume more gas and regular car does not?

Option C provides support that aerodynamics make regular cars more efficient to operate and it make to consume less gasoline.

Please correct me if I am wrong.
Does an Electric CAr work on GAS ?????

i received a private message about this thread.

this problem is exactly identical in logical structure to the following problem from gmac:
https://www.manhattangmat.com/forums/cr- ... t7885.html
you will notice that they didn't even bother to scramble the order of the answer choices! that is, choice (a) in this problem is exactly like choice (a) in the prep problem, etc.

therefore, you should be able to get everything you need by just reading that thread. there is an immensely helpful, and quite comprehensive, analysis from our instructor michael schwartz ("mschwrtz" on the forum), and i made some comments as well.
