Determine question $28$ to $31$ based on the following problem:

Consider the project with the following estimates for activity times and precedence relationships:

$\backslash$table$[[$Activity$,$Optimistic,Most,Pessimistic,Immediate$],[$Time$,$Likely Time,Time,Predecessor$($s$)],[$A$,3,4,5,--],[$B$,5,7,9,--],[$C$,2,3,10,$A$],[$D$,2,5,8,$B$],[$E$,1,7,7,$B$],[$F$,3,5,7,$C$,$ D$],[$G$,7,8,9,$D$,$ E$],[$H$,2,6,10,$F$]]$

What is the critical path?
