Analyze the first statement

The statement is "Una calaverera es el esqueleto de un cuerpo humano" (A skull is the skeleton of a human body). A skull ("calavera") specifically refers to the bone structure of the head, not the entire skeleton ("esqueleto") of a human body. Therefore, the statement is technically incorrect.

Analyze the second question

The sentence is "Él ______ notas malas." The subject is "Él" (He), and we need the correct imperfect form of the verb "sacar" (to get/take). The imperfect conjugation of "-ar" verbs for "él/ella/usted" ends in "-aba". Thus, "sacaba" is the correct form.
