B. Two
C. Three
D. Zero
33. 五项任务按照顺序排列着。每一个任务与另一个任务都是结束-开始的关系。每一

的总时差。到了今天，任务1 和任务2 按进度完成了。按照进度，剩余任务的时差是多
少天？
A. 一天
B. 二天
C. 三天

34．The critical path time needs to be reduced by 20% .you may take the following actions except:
A.Adding resources
B.Crashing time schedule
C.Eliminating float
D.Paralleling activities
34.当需要减少20% 关键路径时间时，你可以采用下列的行动，但（）除外:
A．增加资源
B．压缩时间
C．消除浮动时间

35．An Activity-On-Node (AON) project diagram shows the following activities on two critical paths,D-E-J-L and D-E-G-I-L. Each activity is at least three days in duration, except for the activity L that is one day in duration. If you are directed to reduce the project by one day, which activities are MOST likely to change?
A. L
B.E or J
C.G or I
D.D or E
35.一个AON 图显示了在两个关键路径上的下列活动：D-E-J-L 和D-E-G-I-L。除了L历时为1 天外，其他每个活动有最少3 天历时。如果你计划减少这个项目历时1 天，哪个活动最可能被修改？
A. L
B.E 或J
C.G 或I
D.D 或E
参考答案：D。有二条关键路径，要减少1 天的历时，那么应该修改共同的活动：D 或E或L。但活动L 只有1 天，进度压缩是不改变范围的，排除活动L。那么就只有活动D或E 了，即选项D

36.You are a project manager for a new product development project that has four levels in the work breakdown structure, and has been sequenced using the precedence diagramming method.
