Choice 1: I need at least a few examples for each new definition. The more examples, the better I will understand the definitions. I thus prefer slow-paced textbooks that have the number of examples I need. Choice 2: I need at least one example for each definition to make sure I have a good sense of the meaning of the definition. More would be nice as well but not absolutely necessary. Most textbooks fulfill my needs, but I prefer to avoid fast-paced textbooks. Choice 3: It would be nice to read one example, but only one, to grasp new definitions. If I read more examples than one, I will be wasting valuable studying time. I can handle most fast-paced textbooks, and if examples are missing, it's ok. But one example for each definition would be nice. Choice 4: I don't need examples. I can just read a definition and then fully understand the applications and theorems involving it. I prefer to avoid slow-paced textbooks that have too many examples and explanations that would slow me down.
