This document discusses comparing and contrasting as a comprehension strategy. Comparing shows similarities, while contrasting shows differences. When comparing and contrasting two things, they should be in the same category, like two fruits or two entertainers. Comparing and contrasting helps understand unfamiliar things by relating them to familiar things, and can be used to evaluate which of two things is better. Words like "both," "similarly," and "whereas" are used to compare, while words like "although," "however," and "on the contrary" are used to contrast.
