Public opinion may be passive and false or active and real. It is claimed in theory that all governments are ultimately based on the opinion or sanction of the governed. But we find that in practice the people's rights are often trodden down and tyranny and oppression are allowed to continue. The government does it not because the people want it to do so but because they are too idle, too uneducated and too disunited or timid to oppose the govern ment. Such public opinion is passive and false and not an active verdict. But when we find people alert, intelligent and determined to let the government know their will, when they want to exercise actively their voice in the management of their country, we have an instance of true or active public opinion. True public opinion is formed by and expressed through the press, the platform, political parties and educational institutions. These have sacred duties to perform, duties on which depends the ultimate good of the entire community. The press today wields a tremendous influence, So it should support the causes and move ments and condemn the wrong one's and thus teach people to form correct opinion. A free and fair press ventilates the grievances of the public. Thus a healthy relationship develops between the people and the government through out an unbiased press. Political parties also help to create and regulate opinions. No less important part is played by the educational Institutions which train the minds of the young people who will be the citizens of tomorrow. It has been said that modern Germany and China have been made by their universities. It is necessary that the young and the growing minds should imbibe the spirit of fellow-feeling, the spirit of tolerance, the habit of compromise, and show due regard for the feelings and opinion of others without which a democratic society cannot function, let alone succeed. When there is true awakening of the people, we shall have the real and conscious public opinion. And justice will reign on earth and truly will the voice of the people be the voice of God.

In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: About a year ago, Prime Minister Narendra Modi had told the world that the signature of a chartered accountant on financial statements was, perhaps, more powerful than even one of his own. ‘Just like doctors don’t want people to be ill to get more business, chartered accountants, too, need to safeguard the society’s economic health. Your signature is more powerful than the PM’s, and the government also believes the accounts signed by you’, Modi had said.  Assumptions: I. The CA community, however, may not have woken up to the value of the initials they put on financial statements. Last year has been more of a challenge for the community’s reputation, with banking frauds, asset quality divergences and mid-term auditor resignations dominating the headlines.  II.

But even basic logic just went out of the window and banks together kept dishing out loans to such companies even when their annual turnover was half of the total debt.
