Project Test Bank is composed of activities we will refer to as A,B,C,and D for convenience (and lack of creativity).Durations and precedence requirements are shown in the table.Each of these activities can be conveniently laddered into two sub-activities of equal duration.The first half of each activity serves as the predecessor to its second half and the first half of the original following activity.What is the expected completion time of the laddered project? $$\begin{array} { | l | l | l | }
\hline \text { Activity } & \text { Length } & \text { Predecessor } \
\hline A & 10 & - \
\hline B & 18 & A \
\hline \text { C } & 14 & A \
\hline D & 20 & B , C \

\end{array}$$
A) 34
B) 38

The expected completion time of the laddered project is 34 weeks. This is because the first half of each activity must be completed before the second half can begin, and the first half of the original following activity must be completed before the second half of the original activity can begin. Therefore, the total completion time is the sum of the durations of all of the activities, which is 34 weeks.
