Is (C) wrong because even it is established that it is informed opposition, it does not mean that when she agrees with the plant, the plant is guaranteed safe?
(eg. maybe she agreed because she was threatened or offered a bribe etc...?)
Thank you
So this is a commonly tested flaw. When I see flaw questions, the first thing I like to do is ask myself. "what has the author failed to consider." In this case, it is just as you pointed out. The author assumes that one possible conclusion is the only possible conclusion. Maybe she was threatened or bribed etc... and the construction is still just as unsafe as before.
However, if we new the reason she opposed the construction before (maybe she did think it was unsafe at the time), and/or the reason she now supports the construction (maybe the engineers decided to implement additional safety measures) then the author would be in a better postion to draw the conclusion she does.
C is wrong because it is tries to make a causal relationship where there isnt one. If it said Smith has a record of outspoken and consistent opposition, so she must be informed, then C would address the assumption that would need to be made (consistent and outspoken=informed).
In this case however, C is redundant. We are to except our premises/background info as given and not question the truth of these.
Finally like you said, it seems out of scope of the "core"
P: Someone with Smith record favors the plant, then there is good reason to believe it to be safe.
P: Smith Favors plant
C: Plant should be built
who cares if her reasons for opposition are opposed?
I was actually looking for an answer that tied "believed to be safe" with "should be built" maybe something like: "Assumes without warrant that anything that is believed to be safe should be built."
