Answer:
A but its a poor choice.
Step-by-step explanation:
Well it's never going to be B. Anyone who has to learn English will tell you its a monster.
I doubt C as well. If they were similar, people from China wouldn't require a lot of tutoring which they usually do.
The author is arguing the exact opposite to D. She thinks it is just fine that she learned a great deal about the world and how she saw things from her mother who had a talent for observations.
I guess you have to pick A but it's an awfully poor choice. The author (Amy Tan I think) is saying much more than A. Vivid is fine and complete languages are fine, but its more than that. Her mother gave her the gift of seeing the world in a whole different way.
