Hola,
The question was ¿Vas _casa de Inéz? Both "para" and "a" were given as correct answers but in the lesson above, the use of "a" is given as also acceptable when associated with the verb "Llevar." I would have used "a" instinctively when talking about a destination but was put off using this because of the instruction.
I think there is something about "destination" that I am not understanding. Can you help?
Saludos
John
