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.
My approach:
Choices
A B C D
EBetween 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
How do you choose between C and D??
