In Korean these sorts of questions are stuctured the same way as the answers themselves. I.e. a potential answer to this question is 이 학생이 저 책을 읽습니다. Notice how the word order is exactly the same in the corresponding question.

So instead of translating an English OSV question "what book does this student read?" directly try extracting the subject, object and verb from the corresponding SVO question "this student reads what book?"

You should get this:

Subject - this student

Verb - reads

Object - what book

Now translate:

Subject - 이 학생이

Verb - 읽습니까

Object - 무슨 책을

And stitch together using Korean SOV grammar:

이 학생이 무슨 책을 읽습니까?

Hopefully anyone confused finds this useful.

Same.
