Directions: Read the following passage and answer the question below.
In a population of about one million, seventeen hundred persons died of tuberculosis in this state in the year 1911– a reduction in thirty years of nearly 50 per cent. A generation has changed completely our outlook on one of the most terrible scourges of the race. It is simply appalling to think of the ravages of this disease in civilized communities. Before the discovery by Robert Koch of the bacillus, we were helpless and hopeless; in an Oriental fatalism we accepted with folded hands a state of affairs which use and want had made bearable. Today, look at the contrast! We are both helpful and hopeful. Knowing the cause of the disease, knowing how it is distributed, better able to recognize the early symptoms, better able to cure a very considerable portion of all early cases, we have gradually organized an enthusiastic campaign which is certain to lead to victory. The figures I have quoted indicate how progressively the mortality is falling. Only, do not let us be disappointed if this comparatively rapid fall is not steadily maintained in the country at large. It is a long fight against a strong enemy, and at the lowest estimate it will take several generations before tuberculosis is placed at last, with leprosy and typhus, among the vanquished diseases. Education, organization, cooperation–these are the weapons of our warfare. Into details I need not enter. The work done by the National Association under the strong guidance of its secretary, Mr. Farrand, the pioneer studies of Trudeau and the optimism which he has brought into the campaign, the splendid demonstration by the New York Board of Health of what organization can do, have helped immensely in this world-wide conflict.
