Diesel-powered trucks manufactured prior to 1990 contribute significantly to the world's air pollution. In 1990, however, the government imposed stricter pollution controls on diesel powered trucks, and beginning in 1995, the government imposed a program of inspections for pre-1990 trucks with increasingly rigorous pollution standards. As the older truck engines fail to pass inspection, truck owners are increasingly retiring their trucks in favor of newer, less-polluting trucks. As a result, the amount of pollution these older trucks emit will steadily decrease over the next ten years.
The two portions in boldface play which of the following roles?
A.The first is a pattern of cause and effect that acts as the third evidence in support of the argument; the second is a conclusion that must be true.
B.The first is a pattern of cause and effect that acts as an evidence in support of this argument; the second is the conclusion that can be drawn from this argument.
C.The first is a pattern of cause and effect that acts as an special evidence in support of the conclusion; the second is a general point that can be drawn from this argument.
D.The first is a fact that acts as a principle in support of this argument; the second is the conclusion that must be drawn from this argument.
E.The first is a final evidence in support of the argument; the second is a conclusion that can be drawn only from the first.

Dear
devikeerthansr,
I'm happy to respond.
I would say that this question is more hair-splitting and picayune that the real GMAT would be. Among other things, it's odd that the two BF segments are right next to each other.
The two portions in boldface play which of the following roles?
A. The first is a pattern of cause and effect that acts as the third evidence in support of the argument; the second is a conclusion that must be true.This one makes the hubristic claim that the argument's conclusion "
must be true." That is not true of any real world argument! The GMAT would never say this. Quite clearly, this is unrealistic, and this answer is wrong.
B. The first is a pattern of cause and effect that acts as an evidence in support of this argument; the second is the conclusion that can be drawn from this argument.This seems reasonable.
C. The first is a pattern of cause and effect that acts as an special evidence in support of the conclusion; the second is a general point that can be drawn from this argument.What in tarnation is "
special evidence"? This is a term the GMAT would never use. Also, it seems a hyperfine point to distinguish a "
conclusion" from a "
general point that can be drawn from this argument." This is not only wrong, but unnecessarily cryptic.
D. The first is a fact that acts as a principle in support of this argument; the second is the conclusion that must be drawn from this argument.Again, this one posits a "
must be true" conclusion. Again, this is unrealistic.
E. The first is a final evidence in support of the argument; the second is a conclusion that can be drawn only from the first.The term "
final evidence" is odd: the first BF happens to be presented as the last piece of evidence, but does this make it "
final evidence"? The second part is also odd: I have never seen a GMAT answer choice specific which part of the argument supports the conclusion.
I agree that the best answer is (B), the OA. I find this question particularly challenging in artificial ways--that is, not in ways that mirror how the GMAT is hard.
Here's a hard question that is more GMAT like:
