"Nosotras comemos en mi restaurante favorito."
Translation:We are eating at my favorite restaurant.
I selected practice and was dropped into guessing conjugating present tense of comer (to eat). I knew what was happening but it was still frustrating. This helped : http://www.dummies.com/languages/spanish/conjugating-the-spanish-verb-comer-to-eat/
We are eating at my favorite restaurant. is actually Progressive Present, and should be translated as Estamos comiendo en mi restaurante favorito.
Nosotras comemos en mi restaurante. is Present Indicative, and should be translated to English as We eat in my favorite restaurant Sometimes Duo is picky about this, so be aware of the difference. http://www.spanishdict.com/conjugate/comer
Ahh, but in this case, the speaker could be telling someone at the office that they and some other ladies from the office are eating at their favorite restaurant for lunch.
”What are you doing for lunch today?"
"Oh, we are eating at my favorite restaurant."
It isn't happening obviously right this very minute, which is what comerando is.. right this very minute I am eating at my favorite restaurant.
So this sentence and translation is absolutely correct, based on the example I gave.
Duo wants you to pay attention to the endings, especially on the "write what you hear" exercises. Nosotros/as is not required in the sentence, unless you want to make it clear that we is referring to a group of women/girls.
Nosotras is the feminine form of nosotros
The 'we' therefore are girls Hope that helped
Nosotras is akin to saying "We women" The gender of restaurant has nothing to do with who is eating in it.
