Answer: Because they are blindly following the tradition of the lottery and are afraid that, if they did not continue with this ritual, it would bring them bad luck.
Explanation:
In "The Lottery", a short story by Shirley Jackson, an annual lottery is held at the end of each June. One citizen who draws a slip of paper with a black spot dies by stoning. By portraying a community that blindly follows this pointless ritual, Jackson mocks people who do not accept a change and stick to the past. The villagers are afraid of the lottery and believe that one innocent individual must be sacrificed so that a good harvest is ensured. They continue to participate in this ritual, regardless of how brutal and senseless it obviously is.
A journey that presents many challenges. 'Unpaved' showing it's not built, you gotta build it (build your future) and 'rocks' 'holes' and 'mud' obviously signifies trouble showing there are many challenges to face in the way. Hope you found this helpful. :)
