The two correct responses that support the inference that commercial honeybees may be responsible for leaving virus deposits on flowers are:
- Wild bumblebees pick up more viruses the closer they forage to honeybee colonies.
- Bumblebees have not been observed entering commercial honeybee hives.
These responses suggest a pathway through which viruses could be transferred from honeybees to the flowers they pollinate, and that wild bumblebees, which are foraging near honeybee colonies, are picking up those viruses.
