F	B,C	12
G	B,C	15
H	E,F	11
I	E,F	25
J	E,F	6
K	D,H	21
L	G,J	25

a.	Draw the PERT/CPM network for this project and determine project's expected completion time and its critical path.
b.	Can activities E and G be performed simultaneously without delaying the minimum project completion time?
c.	Can one person perform A, G, and I without delaying the project?
d.	By how much can activities G and L be delayed without delaying the entire project?
