I got this one wrong, choosing (C) instead of (B) and I want to go through what I did wrong/right and hopefully get some insight from one of you guys.
What I did wrong: I have seen this stimuli before when I was drilling but there was a different question attached (Q22). However, when drilling today I saw this question independently from the test using the Cambridge packets of the questions split up by type. Thus, I only read the "antinuclear activists'" portion of the passage. I should have read the whole thing because that probably would have made this answer more clear.
I thought this was a really strange question because there really isn't a core per se (someone correct me if I am wrong). It is really just asking about the following phrase: "The closing of the nuclear plant is a victory for the antinuclear group." Thus, it was really hard to think of a flaw because the flaw is usually in the connection between the premise and the conclusion - this didn't seem to have that.
Antinuclear Activist says...The closing of the nuclear power plant is a victory for the antinuclear cause
Plant Manager says...The availability of cheap power from nonnuclear sources, safety inspections, and repairs made operation uneconomic
→
It was not safety but economic considerations that dictated the plant's closing
→
The closing is not a victory for the antinuclear cause
(A) Simply provides a tidbit of information that may have helped its closing. This might even weaken the argument because it says that, "hey, the antinuclear activists had nothing to do with the plant's closing! the license simply expired."
(D) This is a little bit tempting because it says that closing was a great thing. However, this doesn't really relate to the idea of being a victory for the antinuclear cause. The operating costs were high. So what? The operating costs for other nonnuclear plants are probably high too.
(E) This is just really out of scope, simply providing an example of one thing the plant could do. Who cares?
I am, however, a little confused on (B) and (C).
My thinking for (C) was, "well if the plant closed
only because a nonnuclear source was available, this would mean that the nonnuclear source won over the nuclear source. This seems like a victory to me." I think I got a little confused on the word
cause, I was thinking less about the people that were involved in the cause and more of the idea of actually overtaking nuclear power itself. Is this where I went wrong?
However, I understand why (B) is good too. I initially eliminated this because it wasn't a part of the activist's passage. Well, I learned my lesson. This seems to use a different form of the word cause, perhaps saying that the antinuclear groups really instituted all of the pressure that eventually caused the plant to shut down. Thus, they won in the sense that they wanted this plant closed and they got that plant closed. Good job, antinuclear activists!
