María, ¿quién es amalia? —es mi compañera de cuarto. ella es mi

Okay i need someone to translate this to spanish for me . i would use google but it aint that accurate. my goals for this semester are very cliche. just like any other student i would like to be a straight a student and make the honor roll by the end of this semester. so far im doing really well following my goals. when i achieve my goals my family would be so proud of me. its honestly a good feeling when you do something big (:

Ineed someone who has either taken the unidad 9 prueba_gramática quiz, or at the very least, knows the passive voice in spanish to answer this question. completa la oración con la voz pasiva con se. the cake was eaten. la torta. there are no answer choices provided, you must simply fill in the blanks. 'se comieron' and 'venta de' are incorrect answers, so do not answer with either.

The teacher didn't explain this at all and i don't understand this
