"...play the piano" was marked incorrect. Strange.
I added it to the list of possible translations.
I think "may" should be accepted here, as this is more about permission, not a skill.
I think so
They made a mistake in the English sentence. There should the piano, the in front of the word piano. I will report it.
Does the word можете refer to capability or permission?
Both 'capability' and 'permission' are accepted for можете. The meaning depends on the context.
It should be "The piano"
