A. Some activities on the critical path may have slack.
В. The shortest of all paths through the network is the critical path.
C. Every network has only one critical path.
D. The duration of the critical path is the average duration of all paths in
the project network.
E. On a specific project, there can be multiple critical paths, all with
exactly the same duration.

A fundamental distinction between trend projection and linear
regression is that:
A. trend projection uses two smoothing constants, not just one.
B. in trend projection the independent variable is time; in linear
regression the independent variable need not be time, but can be any
variable with explanatory power.
C. trend projection can be a function of several variables, while linear
regression can only be a function of one variable.
D. only linear regression can have a negative slope.
E. trend projection uses least squares while linear regression does not.
