资料：Placing the right type of workers in close proximity to each other can generate up to a 15 percent increase in organizational performance，according to the study from Cornerstone On Demand，a provider of cloud-based learning and talent-management software，and researchers at Harvard Business School in Massachusetts. For businesses with 2，000 employees, this translates into an additional $1 million in profit each year，the study said.

For the study，researchers examined data from a two-year period of more than 2，000 employees working at a large technology company with locations in the U.S. and Europe. The study’s authors separated workers into three different categories based on the work they produced：

Productive： These employees are very productive，but don’t always produce quality work.

Quality：These workers produce work of superior quality，but aren’t always productive.

Generalists： These employees are average in terms of both productivity and quality.

The researchers defined productivity by how long it takes an employee to finish a task，and effectiveness by how often employees need to ask a co-worker for help completing a task.

【主题句】第1自然段Placing the right type of workers in close proximity to each other can generate up to a 15 percent increase in organizational performance，according to the study from Cornerstone On（疑为缺少空格）Demand，a provider of cloud-based learning and talent-management software，and researchers at Harvard Business School in Massachusetts。For businesses with 2，000 employees， this translates into an additional $1 million in profit each year，the study said.根据Cornerstone On Demand（一家基于云的学习和人才管理软件供应商）和马萨诸塞州哈佛商学院研究人员的研究显示，将合适类型的员工安排在彼此附近可以使组织绩效提高。这项研究称，拥有2000名员工的企业每年将获得额外100万美元的利润。

【解析】本题的问题是“第一段的主旨大意是什么？”。 A选项“Cornerstone On Demand是基于云的学习和人才管理软件的供应商”；B选项“将合适类型的工人放在一起将使绩效提高”；C选项“明智的座位安排会影响公司的业绩。”；D选项“关于企业如何获得额外利润的研究”。根据题目中关键词找到主题句，各选项均正确，但最能总结主旨大意的是B选项，A选项不是主要含义，C、D选项不够具体、过于笼统。
