Complete the sentence with the best choice in spanish. at the beginning of each lesson is the  explicación. introducción. escribir. escuchar. apuntes. vocabulario. investigar. en clase. presionar. practicar.

I guess it's refering to the "introducción", which means the "introduction", but maybe it refers to the beginning of the actual lesson and not the class, so it could be "explicación", which means "explanation".

the correct answer would be the first one. " soy jorge de estados unidos, hoy tengo 18 años y puedo vivir en mi casa solo."

explanation:

in the usa you can live alone when you're 18 years old however you can not live in your own apartment when you're 16 years old.
