I've been reading some suggestions to simulate a modern test for the practice tests, and then "take an extra section" from an older test to simulate how the testing would feel day of. But how do you do this?
Do you make a drill with it limited to "Tags and Preptests" then only check off 1 prep test and then check off all the item tags? What do you do then with the drill difficulty slider? Wouldn't the drill difficulty slider not be in effect if you do this because you're just taking all the questions from a section so you can't control the difficulty?
I disagree with this. Events that are really damaging or ruinous could be catastrophic even if it occurs slowly. Even National Geographic considers droughts catastrophic: https://education.nationalgeographic.org/resource/resource-library-catastrophic-weather-events/.
I would say what's wrong with B is that it says "only" something as a catastrophic. The passage doesn't say this. It says "most likely", so there is a chance that something non-catastrophic caused their migration. Maybe they were tracking the migration patterns a particularly beautiful group of butterflies?
