Read without using your pencil or highlighter
It’s been a while, but here’s what I remember:
1. The whole town got ready for the lottery
2. Everyone had to pick a piece of paper out of the black box
3. A woman (I forgot her name) gets the paper with the dot on it
4. The town stones her to death
I would say that it hasn't increased 20% because 1. if the starting percentage was 18%, you would see a larger precentage but that isn't the case.
