Directions (Questions 11-15): Read the given passage carefully and answer the questions that follow.
As science has brought in many comforts it has also brought in many new diseases, hitherto unknown to the human mind. A recent study of 50,000 office workers found that the most common work related illness they suffered was chronic fatigue syndrome, a feeling of perpetual exhaustion which can continue for several months, even years. Next in line were sore throats and stuffy noses. Over 40 percent of the workers suffered headaches; other symptoms were irritability, depression, insomnia, loss of appetite and in women, menstrual disturbances. There are other ‘location specific’ illnesses in addition to the above. Today people are entombed all day in air conditioned, box like structure with glass facade that ‘shield’ everyone from the harsh outside world. The bacteria flourishing in air conditioning ducts and dehumidifier grills of the place cause illnesses of types unknown earlier. For example, many modern architects use pressed wood products like particle board and fiber board for paneling and partitioning. These contain formaldehyde, a harmful chemical. It is released into the air in the form of fumes, and which, if inhaled, can cause breathlessness, sore throats, eye irritation and skin ailments. Computers have revolutionized the office. But they have brought along their own hazards.
Computer keyboards are known to cause a condition known as the carpal tunnel syndrome in which there is a severe pain in the wrist. Then, the visual display units of the computer pose the hazards of electromagnetic radiation. Gazing at the screen for extended periods causes eye strain, blurred vision and headache. An individual cabin may protect one from noise pollution, but those who work in crowded halls have to put up with the din of ringing telephones, humming exhaust fans, air conditioners and coolers and the constant murmur of voices.
