<h2>Right answer:</h2><h3>a. enseña </h3>
Enseña is the more logical answer because it comes from the verb enseñar (to teach). So enseña is the conjugation of this verb for the third person singular in the simple present tense. The simple present tense is used to talk about habitual actions or routines. So Miguel is a math teacher. Finally:
<em>Miguel </em><em>enseña</em><em> matematicas (Miguel </em><em>teaches</em><em> math)</em>

I'm not exactly sure what you're asking, but I'll try.
The answer is "compro" because it's past tense. I should know, I speak both Spanish and English.
