Test Self-control and ego depletion

QUESTION 1: What is "ego depletion"?

Increasing self-control capacity after a demanding task
A state of permanent fatigue that cannot be recharged
The phenomenon by which, when we expend energy on one task, our capacity for self-control for other tasks decreases
The ability to override our impulses

We will have less capacity for self-control and, therefore, probably less patience
It does not affect anything, since they are different energy reserves
We will have more patience because our self-control has been strengthened
Mental effort has no relation to emotional patience
