GMATNinja Could you please help explain why A is correct but D is incorrect?
Appreciate your help.
Let’s take a look at (D):
Quote:
(D) The first is a generalization that the argument seeks to establish; the second is the main conclusion of the argument.
So is the fact that “any new manufacturing job is created either within an existing company or by the start-up of a new company” a fact that the argument
seeks to establish? It’s definitely a generalization, but the argument does not set out to provide any basis for that generalization.
In other words, if an argument
seeks to establish a statement, then the argument must provide some kind of support for the truth of that statement. The argument under consideration does not do that. Instead, it takes for granted, without evidence, that the boldface statement is true. Eliminate (D).
And here’s (A):
Quote:
(A) The first is presented as an obvious truth on which the argument is based; the second is the main conclusion of the argument.
We already identified the second portion in boldface as the argument’s main conclusion, so is the first portion “an obvious truth on which the argument is based”? An obvious truth would be one that needs no support, so the first portion in boldface fits that aspect of (A)’s description. The final consideration is whether the argument is based on that obvious truth. Well, the first boldface statement presents two categories of new jobs, and the conclusion assumes that all new jobs come from one of these two categories.
So the argument is based on the obvious truth presented in the first boldface statement. (A) is correct.
I hope that helps!
