Final answer:
Amy Tan initially used complex language to prove her English skills, but later switched to simpler English to express herself more authentically and clearly, making her writing more accessible.
Step-by-step explanation:
When Amy Tan first began writing her essay, she used "big" words to demonstrate her proficiency in English. However, she later chose to write in "simpler" English because it better reflected her voice and allowed her to communicate her ideas more effectively. Tan's decision is rooted in the principle that the power of one's writing comes not from using complex vocabulary but from the ability to convey thoughts and emotions in an authentic and clear way. Writing in simpler English removes the barriers to understanding for readers and makes the content more accessible.
