I wrote: "The houses are on fire". Why is it wrong?
I reported it
I also used it because for me it's more natural in English, though I'm not a native speaker. I flagged it.
As a native English speaker, I think "The houses are burning," sounds fine. If anything, it's more dramatic than just saying "The houses are on fire."
I misread ‘houses’ as ‘horses’ and thought that this was rather a morbid sentence.
Maybe it's just Ponyta
Mein Her-... haus brennt!
They must've ignored the Duolingo reminders for too long
