Answer:
Parvulario significa preescolar.
El nivel básico es el único nivel obligatorio.
En Chile uno se puede graduar de la universidad en tres anos.
Explanation:
we need to choose the sentences that are true, let's analyze all of them:
1 )"Parvulario significa preescolar."
Parvulario means something like "infant school", and preescolar means "preschool", so both words may be used with the same meaning, then this sentence is true.
2) "El nivel básico es el único nivel obligatorio."
Here says "The basic level is the only one obligatory"
this is true.
3) "En Chile uno se puede graduar de la universidad en tres anos."
this says something like "In Chile you can finish university in 3 years"
This is true, obviously depends on the career you are studying, there are ones that last for 3 years, and a lot of other tath need more years. So this is true.
4) "No hay diferencia entre el sistema escolar de Chile y los EE.UU."
This says something like "There is no difference between the school system in Chile and EE.UU"
This is clearly false, the focus of both systems is clearly different.
5) "Los estudios universitarios son gratis o muy baratos en Chile"
This says something like "The university studies are free or very cheap in Chile"
This depends on what you define by "very cheap", but they aren't free, and the cost are high for the average citizen, so this is false.
