Question 11 Diagramming

Is there any more help to be had in regards to how to diagram this? I found the video explanation to be almost the opposite of helpful. She doesn't explain the diagramming at all. I have better success just going with my gut.

Hi @Alex-Ward,

Let me try to help with diagramming this. We can diagram "X unless Y "as ~Y - > X. The first sentence of the stimulus gives us an "unless," and so we apply this rule to it. The first sentence we diagram as

PS = problems (of low wages and high-stress working conditions in nursing profession) are solved
AGNAA = (nursing schools) attract a greater number of able applicants

~PS - > ~AGNAA

The second sentence is a simple if-then, though the necessary condition is ad is junction. Also notice that the pool of able applicants not increasing beyond the current level is the same thing as the schools not attracting a greater number of able applicants, or ~AGNAA.

LES = lower its entrance standards
SN = (acute) shortage of nurses

~AGNAA - > LES v SN

The third sentence isn't really relevant to the argument, so we don't Ned to diagram it. The fourth sentence is our final one, and it tells us

CHQHM = current high quality of health care maintained

LES v SN - > ~CHQHCM

And so we can see that we can make a chain with what we've written:

~PS - > ~AGNAA - > (LES v SN) - > ~CHQHCM

And we can thus conclude that

~PS - > ~CHQHCM

Which is what (E) tells us. Hope this helps!
