Guilty as charged.some of my esteemed colleagues ask "Have you a question for us?"
As I suggested in post #2.Try:
Are you a good swimmer?
It is a question made by a non native speaker in a monthly test in Egypt.Both b) and d) result in grammatically correct sentences. Neither of them results in a natural sentence because native speakers would say "Can you swim well?" or "Are you a good swimmer?" No native speaker would open a natural question with "Do you have/Have you the ability to ...?" when "Can you ...?" suffices.
Where did you find this exercise? What grammar/vocabulary point was it trying to test?
I'm getting old and forgetful.As I suggested in post #2.
You may be getting old and forgetful but you haven’t lost your sense of humor, Tarheel.I'm getting old and forgetful.
As emsr2d2 suggested in post #2."Do you have the ability..." is a roundabout way of asking "can you...".
