The well-prepared test taker, just like the well-coached basketball team, should be best prepared for the most likely outcome. A well-coached basketball team, like, say the Warriors of the Golden State, should have been exceedingly well-prepared for the most likely outcome playing the Rockets of Houston last night.
Describe questions (questions that ask of an argument’s “method of reasoning” or how the argument “proceeds”) have kind of a funny place on the LSAT. On the one hand, they’re not terribly common. You might see a couple on test day, or you might just as easily not see any at all. But the skill they test, describing reasoning with the subject matter abstracted out, is important to a lot of things on the LSAT.
