Passage 3
Questions 31 to 35 are based on the following passage :
Summers with father were always enjoyable. Swimming , hiking , boating , fishing—the days were not long enough to contain all of our activities. There never seemed to be enough time to go to church, which disturbed some friends and relations. Accused of neglecting this part of our education, my father instituted a summer school for my brother and me . However, his summer course included ancient history, which Papa felt our schools neglected ,and navigation, in which we first had a formal examination in the dining room, part of which consisted of tying several knots in a given time limit. Then we were each separately sent on what was grandly referred to as a cruise in my father’s 18-foot knockabout, spending the night on board, and loaded down, according to my mother, with enough food for a week. I remember that on my cruise I was required to formally plot our course, using the tide table, even though our goal was an island I could see quite clearly across the water in the distance.

Passage 4
Questions 48 to 52 are based on the following passage:
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 cancer is related to the diet as well, especially cancer of the colon . Different cultures are more prone to contract certain illnesses because of the food that is characteristic in these cultures. That food related to illness is not a new discovery. In 1945 , government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.
The additives which we eat are not all so direct. Farmers often give penicillin to beef 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 medicinal 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.
