Question #11 in S&N Homework - last sentence

Hi, The last sentence says: It is clear that with EITHER a shortage of nurses OR lowered entrance standards for the profession, the current high quality of health care cannot be maintained. I diagramed this as: neg SN or decreased ES-> negate CQHCM In the video explanation Naz did not negate SN- why not? I thought the either or rule says neg X? Thanks for your help in advance!

@sharpen7 it seems that you are confusing the following two statements:

(1) Either A or B

(2) Either A or B is sufficient for C

The sentence you are referring to here is (2), not (1).

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

I don't understand the differences between the two

@alymathieu let's diagram them.

(1) Either A or B

not A ==> B
not B ==> A

(2) Either A or B is sufficient for C

A or B ==> C
not C ==> not A & not B

Can you see the difference now?
