Translation:Anna is eating pasta and Lukas is eating rice.
Hi there, when you write "is eating", the meaning is action, or present continuous (it's happening right now), on the other hand for "eats", the meaning is a passive voice, means that you eat at any time "pasta or noodles". In my case I wrote " Anna is eating pasta and Lucas eats..." I was evaluated as wrong. Why? because of the above. In other words, the difference between "is eating" and "eats", is the immediate action of the first postulate.
you can't know by only reading the sentence if the action is happening right now, or if it is a repeated action
I do not understand why they don't take the both answers as correct
Answers in either present simple or present continuous are accepted.
(But you can't mix tenses inside the same sentence, e.g. "Anna eats pasta and Lukas is eating rice.")
y is it incorrect
Nobody can see what you wrote, so references to "it" or "this" or "my answer" are not useful.
Please always quote your entire answer when you have a question.
Even better: take a screenshot of the question and your answer, upload it to a website somewhere, and tell us the URL of the image.
Well, this is not the place to make that feedback and I don't know where is.
If you think it's a bug, you could try https://support.duolingo.com/hc/en-us/articles/204728264-How-do-I-report-a-bug- .
But if it's deliberate, I don't know whom one could petition for a possible change.
I believe their decisions are usually data-driven, though (they go with what "works", according to their definition of which numbers have to look good) and don't necessarily seek input from the community.
was still failed for it
Then you probably made a mistake -- perhaps a small unnoticed typo.
Since nobody can see what you wrote: please make a screenshot of the question and your answer in such situations, upload it to a website somewhere (e.g. imgur) and include the URL to the image in your comment asking for why what you wrote was not accepted.
