B.   $400
C.   $10,000
D.   $20,000

Question #2
For an activity in a CPM analysis, the Early Start time is 8 and the Late Start time is 10. Which of the following statements is true?
A.   The slack for this activity is 2
B.   The activity is on the critical path
C.   The Late Finish is 12
D.   The duration of this activity is 2
E.   The Early Finish is 10
Question #3
You have just performed a CPM analysis and have found that more than one path through the project network has zero slack values. What can you conclude?
A.   Only one path is optimal
B.   You have multiple critical paths
C.   You have incorrectly performed the analysis
D.   The project will not be completed by the desired time
Question #4
Which of the following statements regarding CPM networks is true?
A.   The late start of an activity is its late finish plus its duration.
B.   There can be multiple critical paths on the same project, all with different durations.
C.   If a specific project has multiple critical paths, all of them will have the same duration.
D.   The early finish of an activity is the latest early start of all preceding activities.
Question #5
Slack is the amount of time an activity can be delayed without delaying the entire project.
A.   True
B.   False
Question #6
Which of the following statements regarding PERT analysis is true?
A.   Project variance is the sum of all activity variances.
B.   Project standard deviation is the sum of all critical activity standard deviations.
C.   Only critical activities contribute to the project variance.
D.   Each activity has two estimates of its duration.
E.   The most likely time is equivalent to the expected activity time.
Question #7
An activity on a PERT network has these time estimates: optimistic = 2, most likely = 5, and pessimistic = 10. What is its expected activity time?
A.   10.67
B.   5.67
C.   5.00
D.   5.33
E.   32.00
Question #8
Which of these statements regarding time-cost tradeoffs in CPM networks is true?
A.   Activities not on the critical path can never be on the critical path, even after crashing.
B.   The crash time always exceeds the normal time.
C.   Crashing a project often reduces the length of long-duration, but noncritical, activities.
D.   Crashing is not possible unless there are multiple critical paths.
E.   Crashing shortens the project duration by assigning more resources to one or more of the critical tasks.
Question #9

B.   pressure to mask delays with false status reports.
C.   gifts from contractors.

C.   Gantt charts give a timeline and precedence relationships for each activity of a project.
D.     
E.   Gantt charts use the four standard spines of Methods, Materials, Manpower, and Machinery.
F.   Gantt charts are visual devices that show the duration of activities in a project.
Question #14
Which of the following statements regarding critical paths is true?
A.   The shortest of all paths through the network is the critical path.
B.   Some activities on the critical path may have slack.
C.   Every network has only one critical path.
D.   On a specific project, there can be multiple critical paths, all with exactly the same duration.
E.   The duration of the critical path is the average duration of all paths in the project network.
