Read the following passage and answer questions

The difference between a physician and a quack is this - a physician knows and admits that his powers are limited. He can aid nature. He can help her remove obstruction and clear away abnormal growth; but he cannot recreate a broken constitution, or make a perforated a lung do the work of a sound one. But a quack with his pills, and his plasters, and his potions, will undertake to cure all the ills that flesh is heir to. In like manner the genuine reformer knows that the living law is the thought of the people, and that all Parliament can do is to fit thought to the life of the nation. It is not so much speed in legislation that is wanted, as still. It is not quantity, but quality, that is required. The highest interests of the State would often be better served by the wise and liberal administration of old laws than by high pressure production of new and imperfect one. Obstruction or no obstruction, necessary legislation will come in due time if people want it. Free speech is more precious than all the measures in the ministerial portfolio. Error of opinion may be tolerated as long as there is the right to combat it. Discussion is a bulwark against oppression, and the sheet-anchor of liberty.
