GMATNinja Could you please help me break down and understand the premise in this question?
I'm not sure if this is why you're struggling with this question, but the chronology in the passage is a little bit funky. So let's start by breaking down the chronology.
Quote:
Defense Department analysts worry that the ability of the United States to wage a prolonged war would be seriously endangered if the machine-tool manufacturing base shrinks further. Before the Defense Department publicly connected this security issue with the import quota issue, however, the machine-tool industry raised the national security issue in its petition for import quotas.
In the first sentence we know that the Defense Department is worried because the machine-tool manufacturing base (that's a mouthful -- we'll call it the "industry" from here on out) has shrunk
in the past. The beginning of the second sentence implies that the Defense Department has brought up the import quota issue because of the stuff in the first sentence. This gives us the following chronology so far:
1. the industry shrank
2. the Defense Department became worried
3. the Defense Department raised the import quota issue
So far, so good. The second half of the second sentence tells us that the industry did two things
before the Defense Department raised the import quota issue (#3 above):
- the industry raised the national security issue (presumably the shrinking of the industry)
- the industry petitioned for import quotas
Now that we have that timeline clear, hopefully it'll be easier to answer the question of
why the industry raised the national security issue!
So, which answer choice contributes most to an explanation of the machine-tool industry raising this issue?
Quote:
(A) When the aircraft industries retooled, they provided a large amount of work for tool builders.
Making sure that there are lots of jobs for tool builders is great, but does it help us understand why the industry raised the national security issue? Not really. This answer choice helps us understand why the industry might be seeking help from the government, but it doesn't help us understand why the industry
specifically raised the national security issue. So we can eliminate answer choice (A).
Quote:
(B) The Defense Department is only marginally concerned with the effects of foreign competition on the machine-tool industry.
If the Defense Department isn't particularly concerned with the effects of foreign competition on the industry, it would be odd for the industry to be particularly concerned with the national security effects. After all, it is it
job of the Defense Department to be concerned with national security issues. So this doesn't help explain why the industry is raising the issue. We can eliminate answer choice (B).
Quote:
(C) The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense.
The industry is petitioning for an import quota. It isn't hard to imagine why: if there's an import quota then there are fewer foreigner competitors that the industry has to compete with at home. Answer choice (C) implies that they unsuccessfully tried to petition for import quotas in the past on the basis of some other argument than national security. The argument itself implies the government became more interested in the national security issue once the industry raised the issue –- the Defense Department started paying attention! So answer choice (C) does a pretty good job of explaining why the industry raised the national security issue: other attempts to get governmental protection had failed! We'll leave answer choice (C) in.
Quote:
(D) A few weapons important for defense consist of parts that do not require extensive machining.
Answer choice (D) would downplay the industry's national security argument. If there are weapons that don't require machining, then it isn't as big of a deal if the domestic industry continues to shrink. So this doesn't help explain why the industry raised the national security issue and we can eliminate answer choice (D).
Quote:
(E) Several federal government programs have been designed which will enable domestic machine-tool manufacturing firms to compete successfully with foreign toolmakers.
If there are several programs that have been designed to help the industry, then this downplays the need for the industry's national security argument since they're already being helped by the government. So we can eliminate answer choice (E).
That leaves us with answer choice (C) as the only answer that helps explain why the industry raised the national security issue.
I hope that helps!
