$[20$ points$]$

Using the forward pass$/$backward pass $CP{M}^5$ technique and the AOA$/$ADM activity network diagram $($for

the project$)$ below:

i$.$ Determine the activities on the project's critical path $(5$ points$)$

ii$.$ Determine the project duration $(5$ points$)$

iii. Reverse engineer the activity schedule $($Activity IDs, Durations, and Precedence Relationships$)$

$(10$ points$)$

The numbers on the arrows$/$arcs$/$links represent the activity durations $($in days$).$ A pair of connected nodes

$($e$.$g$.1-2,$ or $4-6)$ represents an activity or dummy activity.
