The result of Clayton’s recent test that birds hid

答案:

正确答案:foresight解析:由题干中的Clayton’s recent test定位到倒数第2段的首句和末句Dr.Clayton recently tested her scrub jays for foresight...what they’ll need and where they’ll need it.此处需填入名词性成分。原文该段首句指出实验的目的是“测试灌丛鸦是否有预见性”;末句指出“测试结果显示它们能为将来的需要采取措施”,即结果符合测试目的。所以foresight就是答案。
