GMATOntheGo CR Bold Faced Test Q #2
Modern high intelligence safety chips, which are found in most of cars today, are made with low-power circuitry, which is more susceptible to interference than the analog switches used in older vehicles. While on the road, the chips receive electro magnetic signals from other cars and safety devices on the road. Recently, a few cars with low-power circuitry veered off course while on the road, the controls jammed when the cars passed by power generators or transformers that generate high frequency electro magnetic waves. Clearly, modern high intelligence safety chips are being put at risk by high frequency electromagnetic wave generators such as high intensity power generators and transformers.
The two portions in boldface play which of the following roles?
A. The first is a principle that the argument relies on and the second is a conclusion that can be drawn from the first.
B. The first is a fact that argument relies on and the second is a conclusion that must be drawn from this argument.
C. The first acknowledges a consideration that supports that main position; the second is that conclusion.
D. The first is an evidence that supports the conclusion, the second is that conclusion.
E. The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument.
Answer given is C, but I picked up D. I am extremely confused between C & D. How is D incorrect ? How can one distinguish a BF as evidence or as a consideration ?
Moreover, this is the answer explanation given: The first Bold face sentence is evidence that the argument as a whole depends on. The second is a conclusion based on this. Option C expresses this and is therefore the correct response.
By this logic, shouldn’t D be the correct answer ?
Is this an official question?
I do not recommend studying from non-official sources, which most of the time seem to have dubious answers.
