I recently did AP3 RRE1 Exc1 PF1 and didn't get question 10 correct. I chose A because it mentioned synthetic products ... which does not mean that they are natural. However, this choice was incorrect. Can anyone explain how they got the right answer?
For Q4: I thought D was totally wrong and I was completely sure of it because I thought to myself, "How could we possibly know what's in the best interest for the military?" I fell for answers ...
