Q.1 Read the following passage carefully and write the option you consider the most appropriate, in your answer sheet.
It is probable that illness and infection caused by food contaminated with bacteria which produce diseases, have existed since the beginning of time. Drinking water can be made safe by treating it with chlorine. Milk can be made safe by heating it and then packing it in sterilised containers. But it is either very difficult or simply not possible to treat most of the things we eat, in either of these ways. All that can be done is either to prevent bacteria from entering the food, or to stop them form growing after they have entered. For a long time, it was believed that some substances called ptomaines were agents of food poisoning but it was finally discovered that these ptomaine found in rotten food, can be swallowed without the harmful effects that follows it. In 1888, about 60 people, all of whom had eaten meat taken from the same animal, were taken ill, and one man died. Dr. Gaertner, a German bacteriologist, was able to isolate the food poisoning bacteria (Salmonella) which had caused the outbreak; and put forward the theory that all food poisoning was due to the presence of such bacteria.
