Capn Jazz is DEAD ON. If time is an issue for you, as it is for many on verbal, focus on not getting bogged down. Do not re-read. Do not try to absorb every little detail. Do not spend more than 90secs on a question and wind up with the same 50/50 chance you had near the beginning of the question. Tell yourself to focus before each passage and read intently but efficiently. Finding the balance between reading intently and "over-reading" comes with practice.
As for answering the questions, some are really straightforward while others can seem pretty ambiguous. For the tough ones, work it down to two answers and if you can't get the answer in 90 seconds, GUESS between the two choices you've hopefully worked the question down to and move on. It sucks and it's tough to do for us science geeks always wanting a right, calculated answer, but it's necessary to get through VS and not totally bomb the last two passages.
I was a Kaplan guy and didn't follow half of their verbal strategies (the only thing I used was mapping and I only used it for VS, worked for me). I scanned EK for some strategies, and one thing from EK was so simple but helped me so damn much.
Before each passage, close your eyes, take a deep breath, purge your brain of the previous passage, and psyche yourself up for the next one with complete intensity and focus. Takes about 5-10 seconds, but saves you another 30 because you won't keep re-reading the first damn paragraph saying, "wait, what did I just read?" Totally helped me.
Best of luck! With a ton of verbal practice, you can definitely kill that section!
