Answer:
"stress is not necessarily negative"
"the springboard for achieving more"

"stress. ends up an unpleasant event"
Explanation:
The central idea of the passage is that, despite its bad reputation, stress can have both positive and negative effects.
The parts of the text that sustain that idea claim that, although it can be disturbing, stress can also lend impetus to greater achievements, because it stimulates action, as well as it provides higher energy and inspiration.
