+ Strong APA is a specialization of :term:`APA`. In this model, on the
arrival of a :term:`thread`, every thread reachable from the newly arrived
thread is checked to see if an existing thread can be shifted (or deallocated
its processor)
It is a "model" of what? What means "arrival", "reachable from", and
"shifted"?
and the newly arrived thread take its place if the newly arrived thread has a
higher priority. Similar analysis is done when a thread finishes its execution
(Here, the terms task and thread have interchangeable definitions).
Task/thread statement is superfluous.
