To complete the wing assembly of an experimental aircraft, Lockheed Martin has laid out $7$ major activities labeled A through G in the table below. The table also shows their estimated completion time in days and their immediate predecessor. Draw the precedence diagram and identify the critical path.$\backslash$table$[[$Activity$,$Precedence,Time $($Days$)],[$A$,-,2],[$B$,-,5],[$C$,-,1],[$D$,$B$,10],[$E$,$A$,$ D$,3],[$F$,$C$,6],[$G$,$E$,$ F$,8]]$
