This video was really helpful in explaining the basis of the question and the argument. I was really able to put in practice the theory videos in setting up for this one. Though for some reason I was stuck between A and D, and I am still confused why both of these are wrong and also why E is correct. Could you offer a more detailed explanation? Thanks in advance for your help!!!
Glad to hear it.
Here, we need to prove that they're behaving rationally.
(A) and (D) fail for the same reason—telling me what rational people do cannot prove that anyone is rational.
She wears green, so she must be Irish.
A terrible argument, yet certainly not proved by the knowledge that Irish people wear green (Muhammad Ali wore green. Does that make him Irish?).
Same thing here.
I am hoping to confirm whether my process on these questions is correct/efficient. Initially, I try to identify what piece of information the conclusion has that is not presented in the evidence.
I used the contrapositive based on your "unless" conditional statements video. So I got:
no B -> R
no R -> B
Conclusion: No Acquire -> R
In which case we need to connect it (through B):
no Acquire -> no B -> R
Is this a good way?
