I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In intelligent mammals, such as primates, the cerebrum is larger relative to the rest of the brain. Intelligence itself is not easy to define, but indications of intelligence include the ability to learn, matched with behavioral flexibility. Rats, for example, are considered to be highly intelligent, as they can learn and perform new tasks, an ability that may be important when they first colonize a fresh habitat. In some mammals, food gathering appears to be related to intelligence: a deer feeding on plants has a brain smaller than a cat, which must think to outwit its prey."?
The answer to this question is:
Which of the following is a sign of intelligence: ability to learn, feeding on plants, or smaller than a cat?
