Translation:Can you use chopsticks?
You can't tell actually.
The meaning can only be told with a context.
(A) I ask you when we are at the table about to start a Chinese style meal --- This means "Are you able to?"
(B) You ask me when we are discussing what utensil I would use when eating western food --- This means "Will" or "Would". (FYI I did have eaten an ham and egg sandwich with chopsticks yesterday so I didn't need to touch it with my fingers, heehee)
In the case of (A), if I say it in English "Can you use chopsticks?" it may also mean a request not to use other utensils. The Chinese sentence somehow does not have such meaning.
