Answer to Question 1

C

Answer to Question 2

The schedules that might be developed on a project will generally differ in
the level of detail that is represented. The master schedule might/show activities in a
more generic sense as these would be utilized by upper managers in a firm to quickly
grasp the general status of a project as it pertains to the schedule. For Communication
purposes, the network schedule might be converted to a bar chart. Another network
schedule might be utilized to schedule the tasks of specific crews. This might be
appropriately shown with a network diagram. While the level of detail may not
necessarily show every task that must be performed on a given day, there must be
sufficient detail to permit field personnel to begin to understand the general
scheduling objectives at a particular point in time on a project.
