正确答案是
Now scan the passage and answer the questions.
Wings vibrating, hindquarters waggling, a bee dancing on the side of the honeycomb, directs followers to nectar or pollen found on a recent journey. She dances a figure 8 that details distance and direction. A few bees stay with her for several dance circuits. As they get the message and fly out to duplicate her journey, their places are quickly taken by others.
The angle between the dance direction and the vertical is known to signal the direction from the hive to food in relation to the sun. At the center of the figure 8 the bee waggles her abdomen and quivers her wings, indicating the distance. The intensity of the dance plus the samples offered and the lingering odors on the bee's body suggest the type of food and its quality. But many details are still unclear.
