I'm just wondering why (C) is right and (E) is not right.
#18 - If the recording now playing on the jazz program is

E leaves out anything about Lebrun, in the second sentence. A portrait could certainly be acrylic if it were not by Lebrun (or Leonardo da Vinci, or other old-timers). But in C, they confirm that "Since it is what it appears to be, the label is wrong", i.e., the picture is so old that it can't be a Frida Kahlo work, which mirrors the confirmation "the trumpeter was definitely Louis Armstrong" in the stimulus.
Hope that helps,
Sadly, although I got the right answer, I still don't feel really confident on this question and I think I'm missing something basic and fundamental.
1989 LA playing after death —possible
Contrapositive: possible —LA playing after death —1989
Is that how I'm supposed to interpret the stimulus?
...and from there, well, how do you diagram C? And while we're there, how do you diagram B to show that it's not the same thing?
There are really two things claimed about the recording - it's Louis Armstrong and it's from 1989. Thus:
(Louis Armstrong + 1989) Louis Armstrong was playing after his death
Because the necessary condition is impossible, we can infer the negation of the sufficient condition, via the contrapositive. That negated sufficient condition is:
Louis Armstrong or 1989
The author is certain it is Louis Armstrong, so the only possibility left in order to fulfill this "or" statement is that the date was wrong - 1989.
In answer choice (C), you see a similar pattern:
(Frida Kahlo + 17th century Japanese landscape) a 20th century Mexican artist painted in Japan in the 17th century
Because the necessary condition is impossible, either the landscape was not by Frida Kahlo, or it was not a 17th century Japanese landscape. The author says it was a 17th century Japanese landscape. So the attribution to Frida Kahlo is wrong.
Answer choice (B) does not allow us to conclude that the painting is mislabeled. Although it is impossible for a painting to be in two places at once, that doesn't allow us to infer which one is the fake.
Oooo, that makes it much easier to understand. Thanks Robert!
Really having trouble with this problem. Can someone help me explain why E is correct and each other choices are wrong, thank you

However, if you tell us the question number (whether from the homework location or PrepTest location, and topic, we can still help you just as easily! In this case, the question covers Louis Armstrong and jazz, and is from the October 1997 LSAT, LR2, #18, also found as question #243 in one of the problem sets.]
Actually, the correct answer is C. The stimulus is about the inaccurate dating of an artist by the time they lived in, versus a false attribution which puts them in a time they weren't alive. Answer C, saying that Frida Kahlo wasn't from the seventeenth century, is closest to the stimulus, which puts Louis Armstrong as being alive after his death.
Hope this helps,
