Valid Arguments

When determining if an argument is valid based of a true premise- do we use facts outside of the scenario. For example the Sue question; we know that because your name is sue it doesn't make you a girl, but the premise and conclusion logically match. we still use that outside knowledge to answer?

@Hannah if this example was an actual LSAT question, the correct answer choice on a Weaken question would actually have to say something like, "Some people named Sue are boys."

This is another reason we say you want to assume that the premises are true. If an argument is attacked by pointing out a premise is false, it will be very obvious (precisely why the LSAT very rarely takes this approach to weakening).

Hope that helps! Please let us know if you have any other questions.
