Armstrong (please explain why B is wrong)

by max37274 » Sat Feb 20, 2010 2:37 pm
If the recording now playing on the jazz program is really "Louis Armstrong recorded in concert in 1989," as the announcer said, then Louis Armstrong was playing some of the best jazz of his career years after his death. Since the trumpeter was definitely Louis Armstrong, somehow the announcer must have gotten the date of the recording wrong.

The patter of reasoning in the argument above is most similar to that in which one of the following arguments?

(A) The museum is reported as having acquired a painting "by Malvina Hoffman, an artist who died in 1966." But Hoffman was sculptor, not a painter, so the report must be wrong about the acquisition being a painting.

(B) This painting titled La Toilette is Berthe Morisot's La Toilette only if a painting can be in two museums at the same time. Since nothing can be in two places at once, this painting must somehow have been mistitled.

(C) Only if a twentieth-century Mexican artist painted in Japan during the seventeenth century can this work both be "by Frida Kahlo" as labeled and the seventeenth century Japanese landscape it appears to be. Since it is what it appears to be, the label is wrong.

(D) Unless Kathe Kollwitz was both a sculptor and a printmaker, the volunteer museum guide is wrong in his attribution of this sculpture. Since what Kollwitz is known for is her prints, the guide must be wrong.

(E) If this painting is a portrait done in acrylic, it cannot be by Elisabeth Vigee-Lebrun, since acrylic paint was developed only after her death. Thus, since it is definitely a portrait, the paint must not be acrylic.

IMO E
argument:If the recording now playing on the jazz program is really "Louis Armstrong recorded in concert in 1989," as the announcer said

option E:If this painting is a portrait done in acrylic

arg: then Louis Armstrong was playing some of the best jazz of his career years after his death
E:it cannot be by Elisabeth Vigee-Lebrun

arg:Since the trumpeter was definitely Louis Armstrong, somehow the announcer must have gotten the date of the recording wrong.
E:since it is definitely a portrait, the paint must not be acrylic.

the reasoning is very llel

hey max luks like u were not convince by my previous logic , guess what on second thought even i wasn't. so i went back to PS cr bible revised llel reasoning chapter and came back to brk this argument.here how it is

in the argument first the author introduces an assertion :If the recording now playing on the jazz program is really "Louis Armstrong recorded in concert in 1989," as the announcer said
then in the immediate next part of the s/c he contradicts it and creates a paradox by saying that:then Louis Armstrong was playing some of the best jazz of his career years after his death.

and then in the last part of the s/c he resolves the paradox and makes a conclusion by saying :Since the trumpeter was definitely Louis Armstrong, somehow the announcer must have gotten the date of the recording wrong.


so the structure of the argument is like
assertion------>paradox----------->paradox resolved------>conclusion

now we need to find this in the options

a) assertion(The museum is reported as having acquired a painting "by Malvina Hoffman, an artist who died in 1966.")------>paradox(But Hoffman was sculptor, not a painter)----------->paradox resolved(the report must be wrong)------>conclusion(so the report must be wrong about the acquisition being a painting)

b)
assertion------>another assertion-------->conclusion

c)assertion------>another assertion-------->conclusion
d)assertion------>another assertion-------->conclusion
e)assertion------>another assertion-------->conclusion


hence it should be A

can we have OA now

Qustion statement is structured in this way

Assertion..... followed by paradox.... resolving the paradox without weakening assertion

A weeken the assertion..
B again same as A
C is the correct answer.. same logic as question statement
D again weekens the assertion
E too weeken the assertion

A, B, D, and E are framed on same logic ie weekening the assertion.. but C is completely framed as that of question statement.. hope it helps

Birds eye view of the argument : X cannot be Y AND Z at the same time. Since it is definitely Y, hence it is not Z.

X -> recording
Y -> Louis Armstrong
Z -> 1989


Option C:

X-> work
Y -> seventeenth century Japanese landscape
Z -> Freida Kahlo

I must admit that C seems to be the answer. What's OA?
