Use the project described in the table to determine the total resources required for this project if a worker is expected to devote half-time (four hours per day)to this project. $$\begin{array} { | l | l | l | }
\hline \text { Activity } & \text { Duration } & \text { Predecessor } \
\hline A & 5 \text { days } & - - \
\hline B & 4 \text { days } & \text { A } \
\hline \text { C } & 5 \text { days } & \text { A } \
\hline \text { D } & 6 \text { days } & B \
\hline E & 6 \text { days } & \text { C, D } \

The total duration of the project is the sum of the durations of all activities on the critical path: A (5 days) -> B (4 days) -> D (6 days) -> E (6 days) -> F (6 days) = 27 days. At half-time (4 hours per day), the total resources required are 27 days * 4 hours/day = 108 hours. However, considering the longest path (critical path) which is A -> C -> E -> F, the total duration is 23 days, leading to 23 days * 4 hours/day = 92 hours. The correct total resources required should be calculated based on the longest path, which is 23 days * 4 hours/day = 92 hours. However, the closest option to this calculation is 128 hours, which might be a mistake in the options provided.
