The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modem software development. The notions of (36) and scenarios have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions - time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive (37) which is concluded with a well-defined (38) and can be further broken down into (39) -a complete development loop resulting in a release of an executable product, a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group (40) logically by nature.
40（）

B.workflows
C.actions
D.activities
参考答案：D
解析：
统一软件过程是软件工程过程，吸取了近代软件开发的最优方法。实例和场景的概念已被证明为一个极好的捕获功能需求的方法。能用二维时间和内容描述RUP，从时间维上看，软件生命周期被分成几个周期，每个周期又被分成四个连续的阶段，每一阶段都包含一个明确定义的里程碑，每个阶段都由一个或若干个迭代组成，每一个迭代都是一个完整的开发过程，可产生一个可执行产品的新的版本，在构建阶段的每次迭代中，组件不断地向最终系统进化。从所引用学科的内容结构来看，是最本质的逻辑理论活动小组。
