What evidence from the text best supports the inference that honeybees—not bumblebees—are responsible for infecting the studied flowers? Select the two correct answers.

Question

More bumblebees foraging close to apiaries had viruses on their outsides than had active infections.
More than 90 percent of bumblebees collected close to apiaries were infected with black queen cell virus.
All the infected flowers researchers picked and tested were close to apiaries.
All of the bumblebees infected with deformed wing virus were close to apiaries.
All of the honeybees researchers collected were infected with both viruses.

Answer 1

The two pieces of evidence from the text that best support the inference that honeybees—not bumblebees—are responsible for infecting the studied flowers are:

1. All of the honeybees researchers collected were infected with both viruses.
2. All the infected flowers researchers picked and tested were close to apiaries.

These statements suggest that honeybees are actively carrying the viruses and are linked to the segments of flowers that were infected.
