And, if you did PT50 (Sept 2006), you haven't even gotten to the Comparative Passages era of LR. Another major shift; IMO, one for the better (I have the least problems on Comparative Passages, but others have different experiences).
So first lets start with the question stem. It's asking us, which one of the following principles, if accepted (true), would most strongly support the Figorian Development Commission's position.
Something that helps me is circling words that I think would be really hard if they ask about them, because they tend to ask about those parts. One RC passage from the PT50's had 3 questions about one extremely confusing sentence in the passage.
