2. Tessie is chosen as the "winner" because she behaves differently from the other people who make up that society. She is a free spirit and her behavior breaks the pattern defended in that region, causing her to disharmonize the population and therefore needs to be eliminated.
Explanation:
"The Lottery" tells the story of a small town of 300 inhabitants who periodically draws a lottery. Although this seems to be a good and exciting thing, the inhabitants of the city do not seem excited about the lottery and present themselves even fearful, which generates a strong suspense in the story and makes the reader start to think that, perhaps, the lottery, do not represent something good and do not promote a prize desired by people.
