Honeybees communicate the location of food sources through an intricate "waggle dance," in which the angle and duration of the dance encode direction and distance. For decades this was assumed to be unique to honeybees. Recent research, however, has documented similar abstract communication in stingless bees and even some species of ants.
Which choice best describes the function of the second sentence in the text?
- A
It provides additional support for the claim that bees use the waggle dance.
- B
It defines what 'abstract communication' means.
- Ccheck_circle
It establishes a prior assumption that the third sentence will challenge.
- D
It introduces a counterexample to the waggle dance phenomenon.
Explanation
The second sentence sets up the assumption ("unique to honeybees") that the third sentence overturns ("however"). B identifies this setup function.
