Questions 1 to 3 are based on the following reading passage.
Typically the queen honeybee is mother to all the bees in a hive; after mating with several male drones from other colonies, she lays fertilized eggs that develop into all-female worker bees and lays unfertilized eggs that 5 become all-male drones. According to natural selection theory, a worker would enhance her fitness --or ability to propagate her genes-by hatching her own eggs in addition to or in place of the queens. But a typical workers fitness would be diminished if other workers sons, who have 10 less genetic material in common with the worker, supplanted the queens sons . Researchers, testing the hypothesis that workers usually somehow block each others attempts to reproduce, put unfertilized eggs laid by workers and by the queen into a 15 hive. Other workers quickly devoured the workers eggs while leaving the queens eggs alone.
1. Select the sentence that is used as evidence that workers worker bees are capable of thwarting each others attempts to reproduce.
