Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the

COLORS AND EMOTIONS
 Colors are one of the most exciting experiences in life. I love them, and they are just as important to 
me as emotions are. Have you ever wondered how the two are so intimately related? 
 Color directly affects your emotions. Color both reflects the current state of your emotions, and is 
something that you can use to improve or change your emotions . The color that you choose to wear either 
reflects your current state of being, or reflects the color or emotion that you need.
 The colors that you wear affect you much more than they affect the people around you. Of course 
they also affect anyone who comes in contact with you, but you are the one saturated with the color all day!
I even choose items around me based on their color. In the morning, I choose my clothes based on the color
or emotion that I need for the day. So you can consciously use color to control the emotions that you are 
exposed to, which can help you to feel better.
 Color, sound, and emotions are all vibrations. Emotions are literally energy in motion; they are meant
to move and flow. This is the reason that real feelings are the fastest way to get your energy in motion. 
Also, flowing energy is exactly what creates healthy cells in your body. So, the fastest way to be healthy is 
to be open to your real feelings. Alternately, the fastest way to create disease is to inhibit your emotions.
Question 36. What is the main idea of the passage?
A. Colorful clothes can change your mood.
B. Emotions and colors are closely related to each other
C. Colors can help you become healthy
D. Colors are one of the most exciting.
Question 37. Which of the following can be affected by color?
A. Your need for thrills B. Your friend’s feelings
C. Your appetite D. Your mood
Question 38. Who is more influenced by colors you wear?
A. The people around you are more influenced. B. No one is influenced.
C. You are more influenced. D. The people who wear those colors, not you.
Question 39. According to this passage, what create disease?
A. Wearing the color black B. Exposing yourself to bright colors 
C. Being open to your emotions D. Ignoring your emotions
Question 40. The term “intimately” in paragraph 1 is closest in meaning to
A. Clearly B. Closely C. Obviously D. Simply
Question 41. The term “they” in paragraph 3 refers to
A. Emotions B. People C. Colors D. None of the above
Question 42. Why does the author mention that color and emotions are both vibrations?
A. To show how color can affect energy levels in the body. B. Because they both affect how we 
feel.
C. To prove the relationship between emotions and color. D. Because vibrations make you 
healthy.
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 43 to 50.
 Although they are an inexpensive supplier of vitamins, minerals, and high- quality protein, eggs also 
contain a high level of blood cholesterol, one of the major causes of heart diseases. One egg yolk, in fact, 
contains a little more than two- third of the suggested daily cholesterol limit. This knowledge has driven 
egg sales to plummet in recent years, which in turn has brought about the development of several 
alternatives to eating regular eggs. One alternative is to eat substitute eggs. These eggs substitutes are not 
really eggs, but they look somewhat like eggs when they are cooked. They have the advantage of having 
low cholesterol rates, and they can be scrambled or used in banking. One disadvantage, however, is that 
they are not good for frying, poaching, or boiling. A second alternative to regular eggs is a new type of egg,
sometimes called “designer” eggs. These eggs are produced by hens that are fed low- flat diets consisting of
ingredients such as canola oil, flax, and rice bran. In spite of their diet, however, these hens produce eggs 
that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that 
eating their eggs will not raise the blood cholesterol in humans
 Eggs producers claim that their product has been portrayed unfairly. They cite scientific studies to 
back up their claim. And, in fact, studies on the relationship between eggs and human cholesterol levels 
have brought mixed results. It may be that is not the type of eggs that is the main determinant of cholesterol
but the person who is eating the eggs. Some people may be more sensitive to cholesterol derived from food 
than other people. In fact, there is evidence that certainly dietary fats stimulate the body’s production of 
blood cholesterol. Consequently, while it still makes sense to limit one’s intake of eggs, even designer eggs,
it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol 
level.
Question 43. What is the main purpose of the passage?
A. To introduce the idea that dietary at increases the blood cholesterol level.
B. To make people know about the relationship between eggs and cholesterol.
C. To persuade people that eggs are unhealthy and should not be eaten.
D. To convince people to eat “designer” eggs and egg substitutes.
Question 44. What has been the cause for changes in the sale of eggs?
A. Increasing price B. Decreased production
C. Dietary changes in hens D. Concerns about cholesterol
Question 45. What is meant by the phrase “mixed results”?
A. The results are blended B. The results are a composite of things
C. The results are inconclusive D. The results are mingled together
Question 46. Which of the following could best replace the word “somewhat”?
A. in fact B. a little C. indefinitely D. a lot
Question 47. According to the passage, one yolk contains approximately of the suggested daily limit for 
human consumption of cholesterol?
A. 3/4 B. 2/3 C. 1/2 D. 1/3
Question 48. The word “portrayed” could best be replaced by which of the following?
A. studied B. destroyed C. tested D. described
Question 49. What is the meaning of “back up”?
A. reverse B. advance C. block D. support
Question 50. According to the passage, egg substitutes cannot be used to make any of the following types
of eggs EXCEPT...
A. boiled B. poached C. scrambled D. fried

 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.
 Herman Melville, an American author best known today for his novel Moby Dick, was actually 
more popular during his lifetime for some of his other works. He traveled extensively and used the 
knowledge gained during his travels as the basis for his early novels. In 1837, at the age of eighteen, 
Melville signed as a cabin boy on a merchant ship that was to sail from his Massachusetts home to 
Liverpool, England. His experiences on this trip served as a basis for the novel Redburn (1849) . In 1841 
Melville set out on a whaling ship headed for the South Seas. After jumping ship in Tahiti, he wandered 
around the islands of Tahiti and Moorea. This South Sea island sojourn was a backdrop to the novel Omoo 
(1847). After three years away from home, Melville joined up with a U.S. naval frigate that was returning 
to the eastern United States around Cape Horn. The novel White-Jacket (1850) describes this lengthy 
voyage as a navy seaman. With the publication of these early adventure novels, Melville developed a strong
and loyal following among readers eager for his tales of exotic places and situations. However, in 1851, 
with the publication of Moby Dick, Melville's popularity started to diminish. Moby Dick, on one level the 
saga of the hunt for the great white whale, was also a heavily symbolic allegory of the heroic struggle of 
man against the universe. The public was not ready for Melville's literary metamorphosis from romantic 
adventure to philosophical symbolism. It is ironic that the novel that served to diminish Melville's 
popularity during his lifetime is the one for which he is best known today.

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 43 to 50.
Before the 1500’s, the western plains of North America were dominated by
farmers. One group, the Mandans, lived in the upper Missouri River country, primarily
in present-day North Dakota. They had large villages of houses built close together.
The tight arrangement enabled the Mandans to protect themselves more easily from
the attacks of others who might seek to obtain some of the food these highly capable
farmers stored from one year to the next.
The women had primary responsibility for the fields. They had to exercise
considerable skill to produce the desired results, for their northern location meant
fleeting growing seasons. Winter often lingered; autumn could be ushered in by
severe frost. For good measure, during the spring and summer, drought, heat, hail,
grasshoppers, and other frustrations might await the wary grower.
Under such conditions, Mandan women had to grow maize capable of
weathering adversity. They began as early as it appeared feasible to do so in the
spring, clearing the land, using fire to clear stubble from the fields and then planting.
From this point until the first green com could be harvested, the crop required labor
and vigilance.
In August the Mandans picked a smaller amount of the crop before it had
matured fully. This green corn was boiled, dried and shelled, with some of the maize
slated for immediate consumption and the rest stored in animal-skin bags. Later in the
fall, the people picked the rest of the corn. They saved the best of the harvest for
seeds or for trade, with the remainder eaten right away or stored for later use in
underground reserves. With appropriate banking of the extra food, the Mandans
protected themselves against the disaster of crop failure and accompany hunger.
The woman planted another staple, squash, about the first of June, and harvested it
near the time of the green com harvest After they picked it, they sliced it, dried it,
and strung the slices before they stored them. Once again, they saved the seeds from
the best of the year's crop. The Mandans also grew sunflowers and tobacco; the latter
was the particular task of the older men.
Question 43. What is the main topic of the passage?
 A. The agricultural activities of a North American Society. 
 B. Various ways com can be used.
 C. The problems encountered by farmers specializing in growing once crop.
 D. Weather conditions on the western plains.
Question 44. The Mandans built their houses close together in order to
 A. guard their supplies of food B. protect themselves against the weather
 C. allow more room for growing corn D. share farming implements
Question 45. Why does the author believe that the Mandans were skilled farmers?
 A. They developed effective fertilizers. B. They developed new varieties of corn. 
 C. They could grow crops in most types of soil. D. They could grow crops despite adverse weather.
