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

Question

CVTs should be the transmission of choice for car buyers looking to own a car over a longer time frame. While slightly less cost efficient to operate than manual automobile transmissions, continuously variable transmissions (CVTs) offset that loss through lower production costs. CVTs enable the engine to run at its most efficient speed for a range of output speeds. When power is more important than economy, the ratio of the CVT can be changed to allow the engine to turn at the RPM at which it produces greatest power.
 
The argument above assumes which of the following?

Ⓐ There are transmissions less expensive to repair than CVTs.

Ⓑ CVTs have become the most popular choice for car buyers.

Ⓒ Repair or replacement cost for CVTs are not likely to exceed the CVT production cost savings.

Ⓓ CVTs can generate more power than manual transmissions at the same number of RPMs.

Ⓔ CVTs are not significantly less cost efficient to operate than manual transmissions.

I'll try this one :-D

IMO C A. There are transmissions less expensive to repair than CVTs. This information is expressed in the passage. B. CVTs have become the most popular choice for car buyers. Irrelevant. C. Repair or replacement cost for CVTs are not likely to exceed the CVT production cost savings. This choice seems good one. The passage said that CVTs offset the loss in operating cost by lower production cost, means that CVT production cost savings will cover the higher cost in repair or replacement for CVTs, in comparison with manual transmission. D. CVTs can generate more power than manual transmissions at the same number of RPMs. Incorrect. CVTs can't generate power but they can allow the engine to generate power. E. CVTs are not significantly less cost efficient to operate than manual transmissions. This information is already expressed in the passage

My approach: Choices A B C D E Between C and D Applying negation test (C) Repair or replacement cost for CVTs are LIKELY to exceed the CVT production cost savings. This will break the first claim made in support of CVT by the argument " While slightly less cost efficient to operate than MAT ...offset that loss through lower production costs " (D) CVTs can NOT generate more power than manual transmissions at the same number of RPMs. This will break the second claim made in support of CVT by the argument " CVTs enable the engine to run at its most efficient speed for a range of output speeds. When power is more important than economy, the ratio of the CVT can be changed to allow the engine to turn at the RPM at which it produces greatest power " Both options C and D when negated break the reasoning of the argument,so both are assumptions made by the argument. So,I'm stuck :roll:

How do you choose between C and D??

Nevernevergiveup · Answer

Dont complicate the argument so much. Easy :wink:

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 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.
