So to switch it it seems you would have to put it the other way around it would have to say HQM results in PS not HQM results in PS as in answer E. It seems that C would be the answer?
Dear saranash1:
In this case, (C) itself may be a mistaken reversal. --By common sense: even if wage and working-condition problems are solved, high-quality health care might not happen; what if the Black Plague strikes tomorrow and the world's health care systems are overwhelmed? (And (C) basically says that wage and working-condition improvements are enough, a.k.a. "sufficient", to make great health care.) The wage and working-condition problems are *necessary*, but not sufficient, for good health care.
I'm not sure what you are trying to say with "...HQM results in PS not HQM results in PS as in answer E", above; that seems to repeat itself, so you may have flipped part of it around. In any case, the part about "results" is not necessarily right; conditional reasoning is not always cause-and-effect reasoning. Causal reasoning is about "results", i.e., A causes B. Conditional reasoning is different, since "A arrow B" usually doesn't mean "A causes B". --The contrapositive of "slash PS arrow slash HQM" is "HQM arrow PS", true. But that means HQM *needs* PS, not that PS is the "result" of HQM. An important difference.
(E) says that "slash PS arrow slash HQM", which is correct, either by itself or in the contrapositive version, "HQM arrow PS", since good health care needs decent wages and work conditions. You may even want to re-diagram both (E) and (C), to make sure they were diagrammed correctly.
Hope this helps! Good luck!!
