Answer questions $6-9$ using the following table below.

Explanation: Activity $A$ is on the arc that is from node $1($initial node$)$ to node $2($final node$).$

$\backslash$table$[[,$Network,,,$],[\backslash$table$[[$Job$],[$Activity$]],\backslash$table$[[$Initial$],[$Node$]],\backslash$table$[[$Final$],[$Node$]],\backslash$table$[[$Optimistic$],[$Time$]],\backslash$table$[[$Pessimistic$],[$Time$]],\backslash$table$[[$Most$],[$Likely$]]],[$A$,1,2,1,3,2],[$B$,1,4,4,6,5],[$C$,1,3,4,6,5],[$D$,2,6,2,4,3],[$E$,2,4,1,3,2],[$F$,3,4,2,4,3],[$G$,3,5,7,15,9],[$H$,4,6,4,6,5],[$I$,4,7,6,14,10],[$J$,4,5,1,3,2],[$K$,5,7,2,4,3],[$L$,6,7,6,14,10]]$
