Translation:Do you know her husband is an accountant?
Is there a reason that "Did you know her husband is an accountant?" was not accepted?
Why is "did you know her husband is THE accountant?" marked as wrong? After all, there is no 'một' here and if you're going to insert an English article, given previous cases, it's nearly always 'the'.
I continue too to struggle to discern the rule here. Just when I think I am getting close, I slip slide away... "Did" would be another reason marked wrong.
Going by how the sentences are structured, I also believe it should be 'the' accountant. This topic is inconsistent.
