A project has the precedence requirements and activity durations shown in the table.After he draws the network,the project manager decides to represent a few activities by a hammock activity.Which is a legitimate hammock activity for this project? $$\begin{array} { | l | l | l | }
\hline & \text { Tirne } & \text { Predecessor } \
\hline \mathrm { A } & 7 & \
\hline\mathrm { B} & 8 & \mathrm {~A} \
\hline \mathrm { C } & 13 & \mathrm {~A} \

A hammock activity is used to aggregate several activities that span a portion of a project, typically between two milestones or events. In this case, activities B, E, and H can be combined into a hammock activity because they form a sequential chain from the start of activity B to the completion of activity H, without any parallel paths or activities that start outside this sequence and finish inside it, or vice versa.
