"Can you close that door?"

Translation: An féidir leat an doras sin a dhúnadh?

[JackVMacK]

Should "An bhfuil tú in ann an doras sin a dhúnadh?" have been accepted? And if not, why not? I'm having trouble figuring out when to use is féidir le x and when to use tá x in ann.

[scilling]

Yes, that should be equally acceptable.

[JackVMacK]

Go raibh maith agat. I'll start reporting if I use one and get marked wrong because Duo wanted the other.

[kmoriley]

Someday I will remember to but an doras sin before a dhúnadh

[FearAsAnt-Oilean]

what about "an bhfuil tú ábalta an doras sin a dhúnadh?"
Is that not ok?

[MahoganyGaspipe]

My feeling is that it should be accepted. It conveys the necessary meaning of ability, and can be encountered in any of the dialects (and particularly in Ulster, I believe).
