Draw a project network from the following information:

$\backslash$table$[[$Activity$,$Predecessor,Duration$],[$A$,$None,$2],[$B$,$A$,4],[$C$,$A$,3],[$D$,$A$,2],[$E$,$B$,3],[$F$,$C$,6],[$G$,$C$,$D$,5],[$H$,$E$,$F$,6],[$I$,$G$,5],[$J$,$H$,$I,$5]]$

Activities B and H can be shortened to a minimum of $2$ weeks. Which activity would you shorten to reduce the project duration by $2$ weeks? Why?
