Is there any reason why, "Are you able to see them?" isn't accepted as correct. I've reported it anyway but, if it's not accepted, would like to know why not. Thanks!
No, it should work. Also, this sentence is missing a bhfuil.
Just note that this is a ghost sentence and doesn't actually exist in the incubator any more. We and a few other courses are experiencing an issue with ghost sentence at the moment. :)
We seem to be having a mass resurrection of several ghost sentences. This ungrammatical sentence was deleted months ago from the course - we will report the bug, but please comment here if you see it again in the live course.
