The evidence from the text that best supports the analysis that human-raised honeybees may be responsible for harming wild bumblebee populations is:
“Filling in one piece of the puzzle, the study revealed wild bumblebees pick up more viruses the closer they forage to managed honeybee colonies.”
This statement indicates a direct correlation between the proximity of managed honeybee colonies and the increase in viral infections among wild bumblebee populations, suggesting that human-raised honeybees may be a factor in the decline of wild bumblebees.
