I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Finland has used comprehensive schools since the 1970s, in the sense that everyone is expected to complete the nine grades of peruskoulu, from the age 7 to 16. The division to lower comprehensive school (grades 1–6, ala-aste, alakoulu) and upper comprehensive school (grades 7–9, yläaste, yläkoulu) has been discontinued."? 

Are Finland's schools currently divided into grades 1-6 and grades 7-9 or do they cover all nine grade?
