Self-study
Shelton: The recent sharp decline in the number of moose in this region was caused by a large increase in the white-tailed deer population. █████ ███ ████ ██ ███ ███████ ████ █████ ███ █████ ████ █████ █ █████████ ████████ ████ ███ ██ ███████████ ██ ███ █████ ██████ ███████

"Surprising" Phenomenon
In one region, an increased white-tailed deer population spread parasites which caused a decline in the moose population, but an increase in deer didn’t produce the same decline in the neighboring region.
Objective
The right answer will be a hypothesis that explains a key difference between the two regions in question. That difference will likely result in the first region being more susceptible to parasite transfer from deer to moose compared to the neighboring region.
