If you're just skimming the second and third paragraph then it would make complete sense that you're not doing so hot on the specific questions.
Taking detailed notes on the first paragraph would be the reason you are doing well on the general Global questions and also the Except questions because those generally give scenarios that relate to the bigger picture.
That being said, I'm not a big fan of taking detailed notes but rather paraphrasing things in your own words, so that you are more receptive to the correct answer which is usually a paraphrased version of the relevant text
I'd like for you to just make one change, I have a whole lot of tricks up my sleeve but just do this first. Pay close attention to keywords, commas, conclusions, and contrast wherever it is in the passage.
Keywords I mean things like hence yet but since however although still, words that are signaling contrast, conclusions, evidence. These are generally accompanied by a comma but I like to include that point because a comma often sets off a major idea. It's kind of a way of saying hey look at me.
As for conclusions and contrast I would like for you to look at those things where there's a chain of reasoning that leads to a specific conclusion, and boil that down and write it out like a chemical equation.
To improve on the detail questions, become a master of understanding contrast, which is really the most important of all my points here.
The GMAT is absolutely testing your ability to notice when there is change in the passage and to understand both sides of that.
For example when you see the word later it indicates contrast because that means it wasn't that way before.
Just implement this one thing and see how it shifts.
