Hi Freddy,
The conditional relationship here is at the end. Since emotional phenomena can't be explained by physics, chemistry, or neurophysiology, human emotions must not be physical phenomena. We could diagram it as shown below.
NOT explained by PCN
NOT physical phenomena
This is a Justify question, so we are looking for an answer choice that establishes that conclusion (that they are not physical phenomena.
Answer choice (A): This is a mistaken reversal---it shows that if something is not a physical phenomena, it's not explained by science.
Answer choice (B): This answer choice also wouldn't establish what we are looking for, since some human emotions are felt by multiple people. Falling in love is a great example. Two people can fall in love with each other. It's not always a solo endeavor.
Answer choice (C): This answer choice tries to link the three sciences described in the stimulus to one another, but doesn't establish that they are required for something to be a physical phenomena.
Answer choice (D): This says NOT physical
emotional. But that doesn't establish that something that isn't PCN isn't physical.
Answer choice (E): This is the correct answer because it is the contrapositive of the relationship the stimulus wants us to draw. It says if physical
explained by PCN. That is enough to let us draw the conclusion of the stimulus.
Hope that helps!
