This question is about the article "The Flight from Conversation" by Sherry Turkle.
Answer:
Turkle uses the allusion to strengthen the argument she made in the paragraph.
Step-by-step explanation:
In paragraph 9, Turkle shows why communication via devices has become so popular in our society. She says that this success is because the devices allow us to have communication as far as we can control. This is because this communication is neither too much nor too little, but it is enough within the standards that we ourselves have established. To emphasize this argument, she uses the allusion to Goldilocks effectively, which explains the tendency of people to like things that are not so simple, but are not so complicated.
