What does the comparison to human sweat help the reader understand?
On a hot day, the temperature inside a honeybee hive must stay close to a steady level, or the young bees developing inside the wax cells can be harmed. To prevent this, some workers stand at the entrance and fan their wings, pushing warm air out. Others collect water and spread tiny droplets across the comb. As the water evaporates, the heat in the hive drops, in the same way that sweat cools human skin. Few creatures work together so precisely to regulate the temperature of their home. Scientists studying the hive have found that no single bee gives the orders: each worker simply responds to the heat around it.
Answer and explanation
Correct answer: D. How evaporating water takes heat away
Answer: how evaporation removes heat. Why not the others: The comparison is about cooling, not wing speed, job selection or the cause of heat.
- Step 1: Sweat cools skin as it evaporates.
- Step 2: The same process cools the comb when the droplets evaporate.
