''Determine what the main purpose of (sth) is'' or ''Determine what is the main purpose of (sth)''
Is there a difference in structure when saying or writing that kind of sentences?
Determine what what the main purpose of (sth) is.
This is a statement
What is the main purpose of (sith)?
This is a question.
Both statement and question need the verb TO BE (is).
