"I don't understand why you get angry" should be accepted

Je ne comprends pas pourquoi tu te fâches.

[HarishAbbe3]

I typed "I don't understand why are you getting angry" instead of "i don't know why you are getting angry " and was not accepted, don't know why?

[Teo-GN]

It is incorrect, in English, to swap the verb and the auxiliary in indirect questions. Only direct questions do that (“Why are you getting angry?”)

[Netto_JM]

That's how I would've said that, reported!

I assume that English is not your first language. What you may have heard spoken is "I don't understand. Why are you getting angry?" I am not suggesting that this is a correct response for this exercise, but it would account for the confusion.

'mets en colère' - why there is no liason between mets et en?

[EquineLover2]

Can "en colere" be translated as "upset" or just "angry"? In English I use both terms interchangeably.

[BoSwicegood]

I know that Duo prefers angry, but would mad be accepted?
