Are commercial honeybees making wild bees sick?: What they found
All of the honeybee colonies tested by the researchers were positive for both viruses, an unfortunate but common occurrence for commercial colonies.
But the number of wild bumblebees carrying viruses varied depending on the proximity to the domesticated hives. There was also variation between the two viruses.
More than 90 percent of bumblebees collected close to apiaries carried black queen cell virus. In sites farther from apiaries, and where no honeybees were foraging, just under 40 percent were positive for this virus. When the researchers checked for actual infections, they found that the proximity to an apiary wasn’t telling of whether a bumblebee was infected with black queen cell virus. That means sites near and far from a commercial beehive had the same abundance of black queen cell virus infections.
The connection was clearer for deformed wing virus infections. Twenty percent of bumblebees foraging close to apiaries carried the virus on their outsides and 10 percent had active infections. But in sites more than a half mile away from an apiary, where honeybees were absent, not a single bumblebee tested positive for deformed wing virus — as a carrier or with an infection.
When the researchers looked at infected flowers, they noticed a similar trend. Of the 20 percent of flowers that tested positive for viruses, all were picked close to apiaries. And the denser the flower patch in these areas, the higher the rate of deformed wing virus infection in bumblebees.
Researchers claimed they found a relationship between bumblebee infections and how close the bumblebees were to honeybee apiaries.

The evidence from the text that best supports the analysis of a relationship between bumblebee infections and their proximity to honeybee apiaries is:
the percentage of bumblebees infected based on their proximity to apiaries.
This directly demonstrates the correlation between the location of bumblebees relative to the apiaries and the rates of virus infections observed in them.
Based on the paragraph, a Morganism is:
an unlikely but successful sports play.
This is indicated by the description of Morgan's impressive catch despite the collision and falling down, highlighting the success of the play despite the challenges.
The prefix en- in the words enable and endanger means:
to cause to be.
In both words, en- is used to indicate the act of causing something to be in a certain state (to enable or to endanger).
Based on the context, the electorate refers to:
the students in one class.
The term "electorate" in this context suggests a specific group of individuals (the students) who are voting or making a decision regarding the class president.
The word etcetera is a:
noun.
The definition provided describes it as a word, which indicates its part of speech.
In this paragraph, the word endangered has a:
denotative meaning.
This refers to its literal definition of species at risk of extinction, rather than any emotional or connotative implications.
