Q14 - Culture and inscriptions

[nbayar1212]

I understand why A is right but am confused as to why answer choice C is wrong.

The book states "The conclusion of C does not say, as it would have to, that out of the three designers being considered, the only one who could have designed that product is the third."

It seems to me that C does say that in the conclusion, however, as it states "Therefore, Nieves is the only person who could have designed the Ultra 180."

Any help?

Tricky one. The problem with (C) is that it doesn't limit the scope of its conclusion the way that (A) and the argument in the stimulus do. The stimulus concludes that Zi's the only culture in "the surrounding area" that could have made these inscriptions. (A) concludes that "of the three suspects in custody," Kapp must be the burglar. (C) makes a sweeping conclusion without qualification: Nieves is the only person who could have designed the Ultra 180.

But why? They were just three "well-known designers" working there. Maybe someone else was patient and designed it?

I don't see why "Of three well-known designers who worked for Ultra's manufacturer" couldn't act as narrowing a scope just as "known to have inhabited the area surrounding this site" from the stimulus, and "Of the three suspects in custody" from A).

I found a difference between A) and C) where A) denies other two choices with "possibility" term of [i]could[i] just as Stimulus does, C) just states that those other two choices "were impatient."

I thought this distinction was so subtle and hated it..

Originally, I thought C) was closer to the Stimulus because they both have "must have ~" in the first sentence. Sometimes, it's really hard to draw the line of where they should be parallel and where they don't have to.

I would appreciate the clarification on my view.

I think Answer C is wrong because the answer does not adequately limit who designed the shoes. Even though Morris, Nieves, and Ott are three well-known designers, the passage does not state that they were worked on the design.

Meanwhile, Answer A does limit the number to 3 suspects.

This was a tricky question and spent too much time deciding between A and C.

The issue with C. is that it only deals with the "well-known" designers. It's possible that there could have been designers that were not-well-known, but were patient. If this were the case then a "designer-not-well-know" but patient may have designed the Ultra 180.

A. doesn't have this problem, and is thus the correct response.
