SAT History Passages Are So Confusing!

I’m pretty good at most SAT passages, especially science. They’re all interesting and I usually don’t get more than 2 wrong. For history passages, however, I have no idea what is going on. The terminology of those 1800s documents confuse me so much, and I’m getting about 5 wrong on each one. Are there any tricks to this?

I’m going for 1560+, by the way
