Read the passage below and answer the questions that follow:

Self-control is at the root of all virtues. Let a man give the rein to his impulses and passions and from that moment he yields up his moral freedom. He is carried along the current of life and becomes the slave of his strongest desire for the time being. To be morally free, a man must be able to resist instinctive impulse and this can only be done by the exercise of self-control. This is the power, which contributes to the real distinction between physical and moral life, and forms the primary basis of individual character. The strong is he who, by discipline, exercises a constant control over his thoughts and his acts. Millions of vicious desire, that degrade society, and indulges well into the crime that disgrace it, would shrink into insignificance before the advance of self-discipline and self-control. By the watchful exercise of these virtues, character is built-up in chastity, virtue and temperance.
