I am kind of seeing principle questions
"The situation described above conforms most closely to which one of the following generalizations?"
fall into the line of most strongly supported questions
while PSA questions (find the rule/application)
"Which one of the following principles, if valid, would most help to justify the sociologist's argument?"
are ones where we have to find gaps, fill the gap, make sure it is delivered to the right outcome and right situation is being modeled. Am I correct in my line of thinking?
Could another way to look at it or another NA be there is only one thing going for rock music?
