Question

which of the following actions is not necessary if you want to sacar una buena nota?

aprender

prestar atención

estudiar

enseñar

Explanation:

To determine which action is not necessary to get a good grade ("sacar una buena nota"), we analyze each option: "aprender" (learn), "prestar atención" (pay attention), and "estudiar" (study) are all actions a student would do to achieve a good grade. "enseñar" means "to teach", which is the role of a teacher, not a necessary action for a student to get a good grade.

Answer:

D. enseñar
