"They cannot eat in the library."
Translation:Ellos no pueden comer en la biblioteca.
Is there a reason why "No ellos puedan comer en la biblioteca" is marked as wrong but "Ellos no puedan comer en la biblioteca" is right? Is the question just too new or is the order important here?
Amy, if you do put in the ellos, it can't come between the no and the verb. The order is important: the no here comes right before pueden.
