Step-by-step explanation:
The question is referencing Chapter 26 of the novel Holes by Louis Sachar. In this context, the phrase 'What hasn't happened in Green Lake since?' generally refers to the fact that it has not rained in Green Lake since the town's curse started after Miss Katherine (Kissin' Kate Barlow) lost her love, Sam, the onion seller. The tragic event ignited a prolonged drought, making the once lush and vibrant Green Lake into a dry and arid desert. The absence of rain is a symbol of the town’s unresolved past and the ongoing curse.
