$1\mathrm{.}5$ For any two activities in a project to be fast tracked in relation to each other, there are two practical conditions that must both be satisfied. If neither of these conditions are met, then the activities can$$t be executed concurrently.

Be sure to focus on the fast tracking conditions for two activities and not two projects. $($Max$.4$ lines per condition$)$
