easy question - logic

[jsvlad]

21. The "Moses and Sons" social club accepts only people who meet both of the following
two requirements:
A. They are pipe smokers who like disco music.
B. They are stereo owners or Siamese cat owners, but do not own both a stereo and a
Siamese cat.
Which of the following will necessarily lead to the conclusion that the club does not have
a single member?
( 1) There are no pipe smokers who are Siamese cat owners
(2) Siamese cat owners are not pipe smokers, unless they like disco music
(3) People who like disco music are pipe smokers only if they do not own a stereo
(4) People who like disco music are not stereo owners unless they are Siamese cat
owners




Q21-4

Help help wrong

Does 4 mean? People who like disco music are not stereo owners unless they are ALSO Siamese cat owners.
I think ALSO means they own BOTH a stereo and a cat. Without also it means just a cat.

thank you

First question is, what terrible book are you using that has this kind of question? This isn't anything like a real LSAT question, from the wording of the stimulus to the question to the answers. There are more than enough real LSAT quesitons out there, adn I hope you are making use of those too.

4 looks like this to me:

Disco + Stereo --> Siamese

If that is true, there are no members of the club because it violates condition B.

The question reminds me of old GRE questions from the early to mid '90s era.

Good point. I see nothing on a Google search for this question, so that's a definite possibility. 

[Ashley O]

why would someone study old GREs for LR questions? the current GMAT CR questions would be closer.

Of course, this all assumes the person has done every LSAT question and knows them cold, which I think is a stretch.

What's GMAT CR?

[Ashley O]

The GMAT features a type of question known as Critical Reasoning (CR), which has many similarities to LSAT LR questions, but they are generally easier.

[Trainwreck]

But why do those questions instead of LSAT questions?

I feel like I'm missing something

[LSAT Eliminator]

If someone has run out of LSAT LR, and they are studying crazy hard, you'll sometimes see them start up working on GMAT CR questions. Personally, I think it is a mistake because GMAT CR is written in a different manner than LSAT LR, and the way they use logic on the GMAT is a little bit "looser" than on the LSAT.

However, if someone is studying for the GMAT and wants more CR-style problems, doing LSAT LR is a great study tool because LSAT LR is, as Ashley noted, harder than GMAT CR.

Ok, that makes sense. thanks for explaining!
