Question

the rituals of the lottery...
a have become more casual over time.
b are the same as they have been for generations.
c have become stricter and more serious over time.
d have been entirely forgotten by the town.

Explanation:

In "The Lottery" by Shirley Jackson, the lottery rituals have evolved to be more casual over time (e.g., the black box is shabby, some parts of the ritual are forgotten or done less formally). Option B is wrong as rituals changed. Option C is wrong as they became less strict. Option D is wrong as the town still performs the lottery (so rituals aren't entirely forgotten). So A is correct.

Answer:

A. have become more casual over time.
