For the given activities, construct the activity network based on Aetivity $-$ On $-$ Node $($AON$)$ method. Also, perform fonvard and backward pass to calculate the Earliest Start, Earliest Finish, Latest Start and Latest Finish days. Identify the critical path from the activity network and estimate the project duration.$(10)$
