Cual es la fuente de energía que se usa más en México? porque?

Coming from a spanish heritage, i can tell you that is incorrect. the correct way is ella los come (manzanas) todos los dias.

Um ok what was the question

First of all we may refer to the things in classroom in spanish as both los artículos del aula de clases  and los objetos de la clase  we will begin by looking at a picture containing several of these items. we will see them in sentences later to hear  their pronunciation and how they could be used in real contexts

Conocer is the one you’re looking for. saber is to know a fact, conocer is to know something/ someone. hope i’m on time. : )
