formal logic

by xcusemeplz2009 » Wed Oct 07, 2009 11:49 pm
If that insect is a bee, it can only sting once. It only did sting once. So it is a bee.
Which one of the following exhibits a pattern of reasoning most similar to that in the argument above?
(A) Spring is here. It has to be, because when it is spring, I cannot stop sneezing; and I just sneezed.
(B) When the sky is clear, the atmospheric pressure is high. At the moment, it is clearing up, so the atmospheric pressure is bound to be high soon.
(C) Old and brittle paintings are always moved with extreme care. That particular painting is never moved with extreme care. So it must not be old and brittle.
(D) Only one more thunderstorm was needed to ruin that roof. But the roof was still fine a month later. There must not have been any thunderstorm over that month.
(E) To survive in the wild requires physical stamina like Mark's. All the same, Mark's fear of spiders would prevent his survival.

The logic here is :

IF A then B, if B then A

C fits perfectly with this.

I guess it should be A.

I dont think C should be the answer . What C doess is sth like this , If A then B , If not B then not A .

But the question is having a situation where its like if A then B and if B then A

OA

by xcusemeplz2009 » Thu Oct 08, 2009 8:20 am
OA given is A

i too used the same logic but was trap by "cannot stop sneezing " considered it if A than not B.(big misinterpretation)

in C as said logic is if A than B and if not B than not A

Looking at it now, A makes sense
