Does he enjoy hiking?
Where are the books for the class?
Which car should I choose?
When does he get off work?
How long will the meeting last?
How much does the computer cost?
Are you coming to the party tomorrow?
Do you happen to know how much the computer costs?
I'm not sure which care I should choose.
I'm not sure if they will attend the conference next month.
I don't know if he enjoys hiking.
I have no idea how long the meeting will last.
Can you tell me where the books for the class are?
I'm not sure when he gets off work.
I wonder if you are coming to the party tomorrow.
Do you know why they have waited so long to react?
