Anyone want to give it a go for me? Thank you!

I chose D.

Edit for clarification:
2nd section of LR, 4th section overall.

thats the right answer.

SE -most> A18hrs
A18hrs -> ~TLA
HE -> TLA

inferences:
SE <some> ~TLA
HE -> ~A18hrs
SE <some> ~HE
~A18hrs <some> HE

PT 49

section 4 #10

i see the stimulus as:

GA -> EDE (great art -> express deep emotions)
E -> EE (experience -> express emotions)

i see if i digrammed the second sentence as EE -> E i will be able to get the correct answer.

someone care to explain why its EE -> E?

TIA

Here's how I did that one:

G -> EMOT
not CAP -> not EMOT


The contrapositive of the first is:
not EMOT -> not G

so that gives us:
not CAP -> not G
which is answer choice D.

I think it's:
GA --> EDE --> ACE (if it's great artwork then it must express a deep emotion; to express a deep emotion, an artist must be capable of experiencing the emotion).

Contrapositive:
[strike]ACE[/strike] --> [strike]EDE[/strike] --> [strike]GA[/strike] (if the artist isn't capable of experiencing the emotion, then the artwork can't express deep emotions; if the artwork can't express deep emotions, then it can't be a great work of art)

Therefore, D is correct, and it comes from this connected contrapositive:
As long as computers are constructed so as to be incapable of experiencing emotions ([strike]ACE[/strike]), they will not create great artworks ([strike]GA[/strike])

Yeah, that was a nasty one, I remember spending a lot of time on it. I got it right by process of elimination but I'm still not 100% sure I understand why A is right. The way I thought about it was the answer has to involve beauty because that's the part of the conclusion that isn't referred to anywhere else. So that eliminates B and C right away. E is pretty clearly irrelevant to the argument, so it can be tossed and that leaves A and D as the only real contenders. I ended up choosing A over D because everything in the stimulus refers to "most realistic" and "most truthful", and A refers to "most beautiful" whereas D only refers to "beautiful". I'm not crazy about that justification though, but I haven't been able to come up with a logical analysis of why A is correct. If you negate A then that should make the argument break down if A is correct, but again I don't see how it does.

That's smart reasoning though. I should have approached it like that, I was between A and D as well, but chose D for some reasons :lol: .
