Shirt is das T-shirt too.
A t-shirt is a type of shirt, so since this sentence just used "shirts" in general, only "Hemden" is correct and "T-shirt" would be unsuitable.
Woo hoo I finished everything to level 2. Duolingo is a great start and free. I can read and understand to a decent level. Speaking is harder and understanding natives more so. So I think beginning to watch German shows on Netflix is the next step
Pls why is "Das sind europäische Hemden" not a valid translation?
