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 following questions.

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-thirds 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 egg 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 baking. 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.

         Egg 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 result. It may be that it 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 certain 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.

Which of the following could best replace the word 'somewhat'?

A. in fact    

B. a little     

C. indefinitely       

D. a lot

Read the following passage and blacken the letter A, B, C, or D on your answer sheet to indicate the correct answer to the following questions.

A small but growing group of scholar, evolutionary, psychologists, are being to sketch the contours of the human mind as designed by natural selection. Some of them even anticipate the coming of a field called "mismatch theory", which would study maladies resulting from contrasts between the modern environment and the "ancestral environment". The one we were designed for.

There is no shortage of such maladies to study, Rates of depression have been doubling in some industrial countries roughly every 10 years. Suicide is the third most common cause of death among young adults, after car wrecks and homicides.

Evolutionary psychology is a long way from explaining all this with precision, but it is already shedding enough light to challenges some conventional wisdom. It suggests, for example, that the nostalgia for the nuclear family of the 1950s is in some way misguided - that the model family of husband at work and wife

at home is hardly a "natural" and healthful living arrangement, especially for the wives. Moreover, the bygone lifestyles that do look fairly natural in light of evolutionary psychology appear to have been eroded largely by commercialism. Perhaps the biggest surprise from evolutionary psychology it its depiction of the "animal" in us. Freud, and various thinkers since, saw "civilization" as an oppressive force that thwarts basic animal instincts and urges and transmutes them into psychopathology. However, evolutionary psychology suggests that a larger threat to metal health may be the way civilization thwarts civility. There is a gentler, kinder side of human nature, and it seems increasingly to be a victim of repression in modern society.

In this passage, the word "civility" in line 16 is closest in meaning to

A. politeness

B. morality

C. courtesy

D. formality
