OG Quant Review question - I don't quite get this
If xy > 0 , does (x-1)(y-1) = 1 ? 1. x+y = xy 2. x=y OA = A I got it as D and I can explain why. Don't know if I am doing some stupid mistake. 1 . Is sufficient pretty straightforward. 2. (y-1)(y-1)=1 thus y^2 - 2y=0 thus we get either y=0 or y=2. since they have mentioned xy>0 y can't be zero, it h...

Yeah I had picked B too. But OA seems to be A. This question is from GMAT-LSAT CR Doc that I have. I think it is same as 1000CR.
Do you want to try second one I will post the OA later.

LSAT CR
It is illogical to infer a second and different effect from a cause which is known only by one particular effect. This is incorrect because the inferred effect must necessarily be produced by some different characteristic of the cause than is the observed effect, which already serves entirely to des...

It can't definitely be B because it changes the meaning of the argument you can't renew the past, it can be reinterpreted instead as mentioned in the argument.
I had doubt between A & C, but A makes much more sense.

I was following the post because I had picked up D and everyone else was saying B and I don't believe myself with CR because I am extremely bad with it

Doesn't "C" also sound good. The tense is past so we stick to simple tense which is prefered hence was, but should created by and erupted be in paralle with each other?
Am I missing something here?

P(not E or not F) if were mutually exclusive then it is true that P(not E)+ P(not F) = 0.25 1-P(E) + 1-P(F) = 0.25 2-0.25 = P(E) + P(F) (exclusive E & F) events. comes out to be greater than 1 . Probability can't be greater than 1 so it s not exclusive. There has to be some intersection between ...
