Not EDW -> not EDPP -> not TD

Can someone help me understand this better. If we do not have EDW and W is the bases of PP, then we do not have EDPP which means we do not have TD? The transitive chain that was concluded in the video.

    @mprezzy, Happy to help. Let's take a look. Here's how I'd diagram the stimulus: wealth inequality-->threatens democracy (this is our conclusion, and it's the first part of the first sentence of the stimulus) The premises: Wealth-->basis for political power for wealthy individuals True democracy-->equal distribution of power At first, it doesn't appear that these premises connect together. However, if we take the contrapositive of the second premise, we get unequal distribution of power-->not true democracy We can now put the second and first premises together Wealth-->basis for political power for wealthy individuals (unequal distribution of power)-->not true democracy (threatens democracy) While the chain isn't perfect, we can now see the general structure of the argument. We see that the author took a contrapositive of one of the premises to try and chain it with the other premise to get to the conclusion. Since this is a parallel reasoning question, we're looking for the answer choice that follows this general pattern. For eliminating answer choices, we should note that there is no compound (and/or) language nor are there quantifiers, so any answer choice that has these things in it can be eliminated easily. (E) says, "Repeated encroachments on one's leisure time by a demanding job interfere with the requirements of good health. The reason is that good health depends on regular moderate exercise, but adequate leisure time is essential to regular exercise." (E) is a valid argument that aligns well with the diagram of the stimulus. We have a transitive argument structure with three terms being connected to each other. Repeated encroachments of leisure time by demanding job-->interfere with requirements of good health (conclusion) support: good health-->regular exercise regular exercise-->adequate leisure time take the contrapositives of both premises, and we have not regular exercise-->not good health (interfere with requirements of good health) not adequate leisure time (repeated encroachments of leisure time by demanding job)-->not regular exercise combining these, we have not adequate leisure time (repeated encroachments of leisure time by demanding job)-->not regular exercise-->not good health (interfere with requirements of good health) This parallels the stimulus closely, so (E) is the correct answer choice. Hope this helps. Let us know if you have any other questions!
