They should use this kind of interactive assignment wayyyyy earlier in the coursework. This would be massive when learning relationships early on.

@YehudaNissani The way I like to imagine it is by looking at each sentence within its own "world." Take Question 2 for example, which I initially struggled with. The "world" within this question is focused on which period faces a slower change of seawater change. Because the sentence argues that seawater changes more slowly during glacial periods, and slower change is the emphasis of this "world," glacial periods would be the winner. It is the difference between assuming that "slow" = a bad concept and cannot be the winner, and focusing on what the sentence is actually getting at.
