Why ellas instead of ellos?
Because they are talking about girls
How can you tell that from the reading of the sentence?
Because an all-boy OR a mixed-gender group would use the masculine 'ellos' instead.
Why can't we put muchas instead of muchos?
You have to match the gender of restaurante (masculine)
restaurant is masculine, so muchO instead of muchA (a~ feminine)
'A Lot' not accepted 8.20.2020 I've reported it
they eat in a lot of restaurants was marked right to me
I hope duoling looks at they coments because the y really need to fix themselves. BIG TIME.
Duolingo don't look at these comments because the discussion forum is for learners to help each other. To advise them of a problem you need to use the Report button.

"they are eating in a lot of restaurants" Why isn't this accepted?
Cause it is simple present, not 'gerundio'.
