Consider the activity sequences given in the table given below. a) Draw the network diagram based on the information given below. Calculate the ES, EF, LS, LF and slack for each activity and identify the critical path. Can the project be completed in 40 weeks?

Activity	Preceding Activity	Time (Weeks)	ES	EF	LS	LF	Slack
A		10
B		8
C	A, B	6
D	A	8
E	B	9
F	C, D	7
G	D, E	12
H	F, G	10

b) Assume that activity A actually finished at the 9th week, activity B actually finished at the 10th Recalculate the expected project completion time. Which activities would you focus on in order to get the project back on schedule?
