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 from 36 to 42.
(1) Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.
(2) Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.
(3) All the major organs of the body show signs of aging. The brain, for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events.
(4) One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack.
(5) Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fibers can never be replaced once they wear out.
(6) Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.
According to the passage, what condition is responsible for many of the diseases of the old?
A. The arteries have become thickened and constricted
B. The blood vessels lead from the heart.
C. The brain gets smaller in size
D. Bones become lighter and brittle.

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.
(1) Increasing numbers of parents in the U.S. are choosing to teach their children at home. In fact, the U.S. Department of Education has estimated that in 1999, about 850,000 children were being homeschooled. Some educational experts say that the real number is double this estimate, and the ranks of homeschooled children seem to be growing at the average rate of about eleven percent every year.
(2) At one time, there was a theory accounting for homeschooling: it was traditionally used for students who could not attend school because of behavioral or learning difficulties. Today, however, more parents are taking on the responsibility of educating their own children at home due to their dissatisfaction with the educational system. Many parents are unhappy about class size, as well as problems inside the classroom. Teacher shortages and lack of funding mean that, in many schools, one teacher is responsible for thirty or forty students. The children are, therefore, deprived of the attention they need. Escalating classroom violence has also motivated some parents to remove their children from school.
(3) Although there have been a lot of arguments for and against it, homeschooling in the U.S. has become a multi-million dollar industry, and it is growing bigger and bigger. There are now plenty of websites, support groups, and conventions that help parents protect their rights and enable them to learn more about educating their children. Though once it was the only choice for troubled children, homeschooling today is an accepted alternative to an educational system that many believe is failing.
The number of parents who want to teach their own children in the U.S. is _____.
