OK, I give; you're all right. The physics passages contain some answers, so you should read the passages, and the passages are listed first, so you should do that first -- I mean, AAMC is our friend, and they wouldn't ever include extraneous stuff to confuse us or waste our time, right?
The question is not whether you the passages contain information you need, but whether the most efficient way to retrieve that information is by reading the entire passage. My experience, working with many, many students (hundreds, but not thousands; I don't know how many) is that it is not. Zipping back to the passage when you know what you're looking for, and only then, is faster and just as effective.
Now, a lot of my students never get the hang of this; they have to read the passages. But they suffer as a result. A good many, and most of the high-scoring ones, report that not reading, or skimming at most, is best. I believe them, in the agreggate, more than I believe any one person who makes an argument that seems to make sense in support of reading. (Incidentally, what I really believe is that most of the ones who say they don't read, are still spending ten or fifteen seconds skimming, which amounts to roughly teh same thing.)
Assuming you have no faith in my proposition, then do try for yourself, but conduct a real experiment rather than just seeing what feels best. (The best test-taking techniques feel lousy; incidentally, this is more true of VR than anything else.) Put aside an even number of passages whose subject matters and difficulties should be similar. Do half while reading, half while not, timed, with reasonable time limits. (Say you have 50 practice passages; divide a middle chunk for this experiment, say 11, 13, 15, 17, and 19 while reading; 12, 14, 16, 18, and 20 without.) Look at accuracy and speed, with emphasis on speed -- be sure to record how much time you have at the end of each passage. This will help determine what's best for you, without letting you get hung up on this "comfort" thing.
Or just go ahead and read them, because it makes sense to do it and it nerve-wracking not to. Maybe you'll manage to finish anyway.
(As an aside re VR passages -- I've actually had students do them without reading them, as an excercise; it's revealing, but not really a great technique for the test. It is possible, though, to get all or nearly all of the answers in about the same amount of time this way.)
