Reading Comprehension

Read the passage and answer the question.

Honeybees communicate the location of food through a behavior known as the waggle dance. When a forager returns to the hive after finding a rich source of nectar, it moves in a figure-eight pattern on the vertical surface of the comb. The angle of the central waggling run, measured against straight up, tells other bees the direction of the food relative to the sun. The length of the run signals how far away the source is: a longer waggle means a greater distance. Through this dance, a single bee can guide many others to a flower patch it has discovered.
