Then the scientists added a third option, called a decoy（干扰项）, that was similar to either A or B in one characteristic but clearly worse than both in the other (a very bright nest with a small opening, for example). Unlike humans, the ants were not tricked by the decoy, the team reports online today in the Proceedings of the Royal Society B. Although a few colonies picked the third nest, the other colonies did not start favoring A or B and still split evenly between the two．

　　Pratt speculates that ant colonies avoid making the irrational decision because, unlike humans, each ant doesn't evaluate all options before making a choice. When the scouts find a nest, they're unaware of what else is out there, and either they pick the nest or they don't. "The group may do better precisely because the individuals are ignorant," Pratt says．

　　Melissa Bateson, an ethnologist at Newcastle University in the United Kingdom, believes the findings could have "really interesting implications for the benefits of collective decision-making, which we could learn something from." Many grant-review boards, for example, behave like ants: Reviewers see only a subset of the total grant applications and thus have to make a decision without seeing every option．

　　46. The survey of house buying is mentioned to _________．

　　A. reveal the serious housing problems of modern society．

　　B. explain how to make a more reasonable choice when buying houses．
