ACT tests then vs now

I’m trying to get better at the reading section for my ACT in a couple of days. I’m taking the reading sections from online tests from over the years, and I find some of the reading sections to be a lot harder than I expected. I also have the big red act prep book, which has reading passages that I find much more doable. Specifically, I feel the online reading passages from like the 2000s are more SAT style, while the ones from the red book are more evidence-based. Is the current ACT reading section more like the one in the red book or the online ones?
