Remember that “ought to” is a modal verb and is followed by a simple verb.
The “to” is not an infinitive “to.”
Modal auxiliary + subject + main verb + ... ? ➨ Should I call my parents or my friend?
WH- (information) questions can also be formed by putting the WH-question word immediately before the modal.
For example:
What should I do about my problem?
Where should we have dinner tonight?
Why should you believe them?
When should they call their boss?
