Consider the order-requirement digraph. In the order-requirement digraph, determine which tasks. if shortened, would reduce the earliest completion time. \( \begin{array}{ll}T_{4} & T_{5} \\ T_{3} & T_{2} \\ T_{7} & T_{6} \\ T_{1} & \end{array} \) Find the earliest completion time and the new critical path if task \( T_{5} \) is reduced to time length 7 . carliest completion time: Give the earliest completion time as a whole number.
