Which of the following can be inferred from the passage?
Honeybees live in colonies of tens of thousands of individuals, and the survival of the colony depends on finding food. A worker bee that discovers a rich source of nectar returns to the hive and performs a movement known as the waggle dance. The angle of the dance relative to the vertical shows the direction of the food in relation to the sun, while the length of the waggling run shows the distance. Other workers watch the dance in the dark hive and then fly directly to the source. Researchers who moved food sources to new places found that the bees' dances changed accordingly, which suggests that the information in the dance is accurate. Because the dance allows a colony to exploit the best food sources quickly, it is considered one of the most sophisticated forms of animal communication.
Answer and explanation
Correct answer: D. A colony benefits when its workers can share the location of good food quickly
- Step 1: The passage says the dance lets a colony use the best sources quickly. Step 2. This implies a benefit for the colony. Answer: sharing the location quickly benefits the colony. Why not the others: these are not supported.
