I'm a little stuck... Click here to teach me more about this clue!

This clue could be a double definition.

'determination' is the first definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps you can see a link between them that I don't see?

'effective brakes?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'to have' acts as a link.

Can you help me to learn more?

(Other definitions for staying power that I've seen before include "energy and strength" , "Stamina - endurance" .)
