asking people

[Ashiuhto]

Please help me correct the following wording. Thanks!

We asked people such as the PEteachers, the teacher who works in the health center, students, friends, andfamily.
The questions were：
a. Have you ever had troublesleeping?
b. What do you thinkwas the reason for your insomnia?
c. How did you solvethis problem?

The only problem is the omission of spaces between words. Otherwise it reads OK. I've marked the missing spaces with this symbol: ^.
