CVTs should be the transmission of choice for car buyers looking to ow

Dont complicate the argument so much. Easy

CVTs are slightly less cost efficient to operate than manual automobile transmissions, and offset that loss through lower production costs. ..............This indicates that inorder to prefer CVTs, we need to assume that there are no more unexpected costs/surprises

Thus 

Quote:

Repair or replacement cost for CVTs are not more than or less than the CVT production cost savings.

If you negate it, then conclusion that CVTs should be the transmission of choice for car buyers does not make sense.

Option D is incorrect by itself.
CVTs can generate more power than manual transmissions at the specific RPM not at the same number of RPMs..

Can someone please clarify why answer choice C is correct and not answer choice E? I have a few problems with this question.

For one, there would be nothing wrong if the savings from using CVT were nullified by the use of CVT repair or replacement parts. The argument is comparing production vs. operating costs and does not in any way mention repair costs in the stimulus. We don't have any knowledge of the replacement cost of manual transmission. Maybe it costs just as much to repair manual transmissions. In such a case using CVT would still be a preferred option. I fail to see how C is an assumption that must be true for the argument to hold.

Answer choice E directly contradicts a statement in the stimulus. Now from this type of statement you can immediately tell that it isn't from a GMAC source since official questions never have statements that directly contradict a premise in the stimulus (if such a problem exists please refer me to it). The truth is that if this statement were not true the entire argument would fall apart, a behavior true of argument assumptions.

Thus, I do think that answer choice E should be the correct answer to this question, even though I honestly feel the question was not written in a manner consistent with GMAC.

Can someone explain why E is wrong ?
It is stated in the passage that the CVTs are less cost-efficient but it is not explicitly stated how much.
If CVTs are significantly less cost efficient then there is no reason to choose them instead of the manual ones.

Reasoning behind it for me was that this is an assumption question. We are given a premise that there is a " slightly less cost " efficiency for the CVTs, therefore the author did not have to assume anything.
