Respuesta :
I think the issue is that it’s unclear whether Mark talked about his vacation on a Friday or visited the Great Wall on a Friday. Depending on which one it was (I think it would be the former.), I would either say “On Friday, Mark told us about his amazing visit to the Great Wall of China.” or “Mark told us about his amazing Friday visit to the Great Wall of China.”
Answer:
The answer is B:
On Friday, Mark told us about his amazing visit to the Great Wall of China.
