Difficulty level = 6/5

Not sure if this will help anyone, but I answered this quickly doing a VERY shallow (maybe oversimplied) dip:

.

It's either this or that (but not both).

It's not this.

-------------------------------------

Therefore, it's that.

.

It's either 10 cents (normal classroom) or 15 cents (lab)

It's not 10 cents (normal classroom).

-------------------------------------

Therefore, it's 15 cents (lab).

@ogreen26 No problem! :)

@coconut Yeah I was confused too until I watched the video. He explains that it's "some" because the conclusion he draws is that some things are both poisonous and have some benefit. You're right that it's also valid to say "most" if you're drawing your conclusion specifically about potions. His reasoning in the video for going with the more general conclusion is that the LSAT will more commonly test on that sort of interpretation. I hope that helps :)

Never seen a better example of a question to skip on test day

Was anyone else thrown by the word "concern" in the correct answer choice?

@Lexxe So turns out this is true but there's a lesson down the line stating it explicitly lol

Does anyone know if the takeaway below from question #4 is correct?

From the lessons, formal argument #5 is "Most before All". We cannot make a valid conclusion from question #4 because the premises written lawgically are actually "All before Most". We can only draw a conclusion when the "most" arrow comes before the "all" arrow, not the other way around.
