Here's what I'd recommend for roles questions:
(1) Make sure you identify the conclusion of the argument, if there is one. Most roles questions will try to tempt you into saying that one of the two boldface portions is the conclusion, so make sure you know where that conclusion is.
(2) Read EVERYTHING. It's not safe to only read the boldface portions: you need to know their place in the argument as a whole.
(3) Try putting the argument in your own words first. Don't be intimidated by the density of the argument; most roles questions feature quite complex arguments -- more complex than other CR arguments -- but this is because your understanding of the argument doesn't have to be particularly profound. (You don't need to strengthen it, weaken it, or draw any conclusions from it, only describe it in broad terms.) So put in your own words first, then try to find an answer that matches your description.
(4) If you're still stuck, look for excuses to eliminate answers. Is the first bold statement really a "contention", or is it just a fact related by the author? Is the second statement really a "consequence" of the first one, or is merely the opposing view? etc.
