Select all that apply. In which frames is whether required rather than if?
Directly before 'or not'✓Ճիշտ պատասխան
Before an ordinary finite clause with no stated restriction
Directly before a to-infinitive✓Ճիշտ պատասխան
After wonder in every possible context
Բացատրություն
Whether is required immediately before or not and before a to-infinitive. In a plain embedded yes/no clause without those frames, both connectors are standard, so those contexts cannot force a single choice.
