Begin by understanding what the waggle dance communicates: the direction to a food source relative to the sun’s position in the sky. Each option can be evaluated against how bees actually use this dance.
Option 1: 'To confuse rival colonies.' While bees may defend resources, the waggle dance is not a strategy aimed at confusing other colonies. The dance conveys precise directional information, not deceptive signaling intended to mislead rivals. This makes the option misleading about the primary purpose of the dance.
Option 2: 'Because they get tired.' Fatigue is not a functional explanation for changing the waggle angle. The orientation of the dance is a calibrated signal tied to the sun’s location, and it is adjusted systematically, not randomly, due to the bees’ physical state or endurance.
Option 3: 'To trick predators.' Predation pressure is not the mechanism driving the angular adjustments in the dance. The dance’s angle is a communicative cue used by follower bees to locate nectar relative to the sun, not a camouflage or lure strategy against predators.
Option 4: 'To compensate for solar movement.' This captures the core mechanism: as the sun moves across the sky, the angular reference changes. For accurate navigation, foragers must update the dance’s angle to reflect the sun’s changing azimuth, allowing hive mates to interpret the direction to the food source correctly throughout the day. This explanation aligns with established findings on solar-compensated navigation in honeybees.
Overall, the reasoning favors option 4 because it directly accounts for the solar geometry bees must offset when communicating directions via the waggle dance, whereas the other choices describe phenomena that do not fit the function or mechanism of the dance.
