B.The consequence of workers sitting together.

C.The performance of a worker who is surrounded by a group of employees.

参考答案：A

参考解析：

定位至原文段Their analysis measured performance as well as a definitive metric for “spillover” for each employee—the term the researchers used to measure the combined performance of everyone seated around a given employee.根据其所在句子结构可知，破折号之后的内容就是对spillover的解释说明，即“研究人员可以用这个词来衡量坐在特定员工周围的所有人的综合表现”。选项A：坐在某一特定区域的工作人员的综合表现，表达符合文意；选项B：员工们坐在一起的结果，表述片面；选项C：被一群员工包围的员工的表现，表述主体错误，不是某一个人的表现，而是所有人的表现；选项D：公共支出的间接影响，属于无中生有。故本题正确答案选A。
