I had the same issue, OP... one thing that helped was judicious highlighting
within the question stem/answers, not just the passages. Making sure I highlighted a key word/words really helped me focus in on the questions--it makes you think about the individual words, so it makes you take your time understanding the question.
Another strategy is to combine the answer + question stem into a statement to check yourself (see below). For me this worked best when I had either chosen an answer or narrowed down to 2 answers.
