单选题 The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notions of use-cases and (71) 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 (72) which is concluded with a well-defined (73) and can be further broken down into (74) - 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 (75) logically by nature.

【正确答案】 A

【答案解析】[参考译文] RUP(Rational Unified Process)是一种软件工程过程产品，它吸取了现代软件开发中许多成功的实践。事实证明，采用用例(use-cases)和剧情 (scenario)捕获目标系统的功能需求是一种较好的办法。可以采用二维模型来描述RUP——时间和内容。从时间维来看，软件生存周期被划分为不同的周期(cycles)。每个周期又被划分为4个连续的阶段(phase)，每个阶段都包含一个妥善定义的里程碑(milestone)；每个阶段还可以被进一步划分为若干轮迭代 (iterations)。一次迭代是一次完整的开发过程，每次迭代结束时会发布一个可执行的产品，这个产品是正在开发的软件系统的一个子集，它会逐渐扩展为最终系统。内容结构指的是一些将活动(activities)组织在一起的、天然存在的规则。
