How can you tell that (E) strengthens instead of weakens Autoco's expectation? I took (E) as something that weakened the argument since if Autoco's suppliers have on hand a wide range of previously prepared parts designs that can readily be modified for a new car, it seems to me that suppliers did not have any trouble to begin with when Autoco designed all of its cars itself and contracted the parts out (since Autoco's suppliers have on hand a wide range of previously prepared parts designs). To me this meant that there is likely
little cost savings from Autoco's proposed change.
Let's take another look at the expectation (i.e. conclusion) that we are trying to support:
Quote:
Autoco expects
this shift to
reduce the overall time and cost of the design of its next new car.
"This shift" is referring to Autoco's plan "to include its suppliers in designing the parts they are to build," rather than designing the parts in-house. They expect this to save time and cost less because "many parts suppliers have more designers with specialized experience than Autoco has."
Note that the conclusion does not specify the
how much time and money Autoco expects to save -- in your analysis, you state that there would be "little cost savings." In order to answer the question, we don't need to prove that there will be a
great reduction of time and cost, just that there will be an
overall reduction.
Let's look at answer choice (E) and analyze its impact before and after implementing the "shift":
Quote:
(E) Most of the Autoco’s suppliers have on hand a wide range of previously prepared parts designs that can readily be modified for a new car.
Before the "shift": Autoco would use its own resources to design the parts, and then would provide these designs to its suppliers to produce.
After the "shift": Autoco would leverage its suppliers' resources to design the parts. The suppliers already have designs on hand that can be "readily... modified for a new car." From the word "readily" we can infer that this would take less time than designing parts internally, and we can also assume it will cost less to simply modify an existing design than creating one from scratch.
This answer choice definitely supports Autoco's expectation. Answer choice (E) is correct.
