Key problems

I would like to show you one of the main problems of this high school, the students don't understand the meaning of the statemens. The students of 1st of ESO had to do an exercise to fill in the blanks with a, an, or some and one student thought that "or some" was one of the option, she didn't recognize "or" as a connector.



I was very surprised and worried about this kind of problems and I don't really know the reason of them, maybe they are caused because of the low level of Spanish, or because they don't understand what they read, but we must try to help them!
