The problem of water pollution by pesticides can be understood only in context, as part of the world to which it belongs- the pollution of the total environment of making. The pollution entering our waterways comes from many sources, radioactive wastes from reactors, laboratories, and hospitals; fallout from nuclear explosions; domestic wastes from cities and towns; chemical wastes from factories. To these is added a new kind of fallout the chemical sprays applied to crop lands and gardens, forests and fields. Many of the chemical agents in this alarming melange initiate and augment the harmful effects of radiation, and within the group of chemicals themselves there are sinister and little- understood interactions, transformations, and summations of effect.
Even since the chemists began to manufacture substances that nature never invented, the problems of water purification have become complex and the danger to user of water has increased. As we have seen, the production of these synthetic chemicals in large volume begin in the 1940’s. It has now reached such proportion that an appalling deluge of chemical pollution is daily poured into the nation’s waterways. When inextricably mixed with domestic and other wastes discharged into the same water, these chemicals sometimes defy detection by the methods in ordinary use by purification plants. Most of them are so complex that they cannot be identified. In rivers, a really incredible variety of pollutants combine to produce deposits that sanitary engineers can only despairingly refer to as “gunk”.

The word ‘gunk’ in the last line refers:

Directions: Read the passage given below and answer the questions that follow based on the information given in the passage.

IN GORILLA society, power belongs to silverback males. These splendid creatures have numerous status markers besides their back hair: they are bigger than the rest of their band, strike space-filling postures, produce deeper sounds, thump their chests lustily and, in general, exude an air of physical fitness. Things are not that different in the corporate world. The typical chief executive is more than six feet tall, has a deep voice, a good posture, a touch of grey in his thick, lustrous hair and, for his age, a fit body. Bosses spread themselves out behind their large desks. They stand tall when talking to subordinates. Their conversation is laden with prestige pauses and declarative statements. The big difference between gorillas and humans is, of course, that human society changes rapidly. The past few decades have seen a striking change in the distribution of power—between men and women, the West and the emerging world and geeks and non-geeks.

Women run some of America’s largest firms, such as General Motors (Mary Barra) and IBM (Virginia Rometty). More than half of the world’s biggest 2,500 public companies have their headquarters outside the West. Geeks barely out of short trousers run some of the world’s most dynamic businesses. Peter The, one of Silicon Valley’s leading investors, has introduced a blanket rule: never invest in a CEO who wears a suit. Yet it is remarkable, in this supposed age of diversity, how many bosses still conform to the stereotype. First, they are tall: in research for his 2005 book, “Blink”, Malcolm Gladwell found that 30% of CEOs of Fortune 500 companies are 6 feet 2 inches or taller, compared with 3.9% of the American population. People who “sound right” also have a marked advantage in the race for the top. Quantified Communications, a Texas-based company, asked people to evaluate speeches delivered by 120 executives. They found that voice quality accounted for 23% of listeners’ evaluations and the content of the speech only accounted for 11%.
 Academics from the business schools of the University of California, San Diego and Duke University listened to 792 male CEOs giving presentations to investors and found that those with the deepest voices earned $187,000 a year more than the average.
 Physical fitness seems to matter too: a study published this month, by Peter Limbach of the Karlsruhe Institute of Technology and Florian Sonnenburg of the University of Cologne, found that companies in America’s S&P 1500 index whose CEOs had finished a marathon were worth 5% more on average than those whose bosses had not.
