Ecologist: The incidence of alligator attacks on humans in the vicinity of the Blue Lagoon has increased in recent years. Relocating at least half of the Blue Lagoon's alligator population would help decrease the incidence of alligator attacks on humans. The ecologist's claim relies on which of the following assumptions? ["Relocating half of the lagoon's alligator population would not be prohibitively expensive.", 'Not all alligator attacks on humans are reported to authorities.', 'In recent years, there has been no significant change in the size of the alligator population in the Blue Lagoon.', 'There is a correlation between the size of the alligator population and the incidence of alligator attacks on humans.']
