When do we use question marks?
1) When you end a sentence that asks a question. That's it, right? Not quite.
There are two more...
2) When you want to express uncertainty or doubt.
Example: Mr. Yuri's feeding program started from 1959 (?) to 1999.
3) Optionally, when you make a polite request.
Example: Would you please hand me the remote? (Note: "Would you please hand me the remote." would be correct too.)
Here's a video by Paige Carrera discussing when a question mark could be used.
