Could you also use "Je mange durant de ces repas."?
No, because "lors" needs "de" but not "durant. You wan say : "je mange durant ces repas" (or "pendant" or "au cours de ces repas")
Why is je mange pendant ces repas incorrect?
To me, it is correct, but not to Duo, who wants to teach you "lors de"
Why de ces and not just ces
the preposition form is "lors de", not "lors" by itself.
oh ok thanks
It's accepted now
