The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. People of different cultures are more prone to contact certain illnesses because of the characteristic foods they consume.
That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates nitrites (commonly used to preserve color in meat) as well as other food additives caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which ingredients on the packaging label of processed food are helpful or harmful.
The additives that we eat are not all so direct. Farmers often give penicillin to cattle and poultry, and because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are administered to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
A healthy diet is directly related to good health. Often we are unaware of detrimental substances we ingest. Sometimes well-meaning farmers or others who do not realize the consequences add these substances to food without our knowledge.
Question: How has science done to disservice to people?
A. As a result of scientific intervention, some potentially harmful substances have been added to our food
B. The scientists have preserved the color of meats, but not of vegetable
C. It caused a lack of information concerning the value of food
D. Because of science, disease caused by contaminated food has been virtually eradicated.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The air above our head is becoming cleaner. A breath of fresh air has been running right round the planet for the past five years. The planet is apparently purging itself of pollution. Paul Novell of the University of Colorado, the co-author of a report on this phenomenon says, “It seems as if the planet’s own cleaning service has suddenly got a new lease of life. Suddenly, there are a lot of changes going on up there”.
Estimates of the death toll from urban smog have been steadily rising, so the new cleaner trend could have significant consequences for life expectancy in cities as well as for the planet itself. The sudden and unexpected reversal of several decades of worsening pollution extends from the air in city streets to the remotest mid-Pacific Ocean and Antarctica.
Among the pollutants which have begun to disappear from the atmosphere are carbon monoxide, from car exhaust and burning rain forests, and methane from the guts of cattle, paddy fields, and gas fields. Even carbon dioxide, the main gas behind global warning, has fallen slightly.
There are two theories about why pollution is disappearing. First that there is less pollution to start with due to laws to cut down urban smogs and acid rain starting to have a global impact. Second, that the planet may be becoming more efficient at cleaning up.
The main planetary clean-up agent is a chemical called hydroxyl. It is present throughout the atmosphere in tiny quantities and removes most pollutants from the air by oxidizing them. The amount of hydroxyl in the air has fallen by a quarter in 1980s. Now it may be reviving for two reasons: ironically, because the ozone hole has expanded, letting in more ultraviolet radiation into the lower atmosphere, where it manufactures hydroxyl. Then the stricter controls on vehicle exhausts in America and Europe may have cut global carbon monoxide emissions, thereby allowing more hydroxyl to clean up other pollutants.
Question: Based on information in the passage, all of the following information referring to hydroxyl is true EXCEPT __________.
A. oxidization of pollutants is carried out by hydroxyl.
B. ultraviolet radiation increases production of hydroxyl.
C. there is difficulty in destroying carbon dioxide by hydroxyl.
D. the reduction in the ozone layer is beneficial to hydroxyl.
