For many years, ship captains navigating the waters of Antarctica have been intrigued by sightings of emerald icebergs. Scientists have now explained their mystery. Their icebergs are turned upside down. Icebergs are blocks of ice that have broken off huge slabs of frozen snow called ice shelves. Their green appearance results from seawater that has frozen at the bottom over hundreds of years. The frozen sea water has dissolved organic matter which gives it a yellow tone and the fresh water ‘ice shelf’ above has a blue tinge.

Passage
According to the civil laws of most countries, obedience is no longer the duty of a wife, every woman has the political right to vote, but these liberties remain theoretical as long as she does not have economic freedom. A woman supported by a man is not liberated from the male. It is through gainful employment that woman has traveled most of the distance that separated her from the male, and nothing else can guarantee her liberty in practice.
I once heard a maidservant declare, while cleaning the stone floor of a hotel lobby, “I never asked anybody for anything; I succeeded all by myself.” She was as proud of her self-sufficiency as a Rockefeller, Ford or Birla.
However, the mere combination of the right to vote and a job does not mean complete liberation: working, today, is not a liberty.
A recent study of women workers in a car factory shows that they would prefer to stay in the home rather than work in the factory. The majority of women do not escape from the traditional feminine world. Their jobs at the factory do not relieve them of housekeeping burdens; they get from neither society nor their husbands, the assistance they need to become in concrete fact the equals of men.
10) Which of the following helps women
(a) The right to vote
(b) Civil liberties
(c) A job
(d) Wealthy husbands
11) Why does the writer talk about the maidservant in the hotel lobby?
(a) The servants of today will one day be freed from their rich masters
(b) A servant can become as rich as Rockefeller or Birla
(c) Even with a low paid job women can achieve equality
(d) Economic independence is necessary for women’s liberation
12) In which paragraph does the writer say that it is revealed that some woman would not like to work in the factory?
(a) In paragraph four
(b) In paragraph three
(c) I paragraph two
(d) In paragraph one
13) “These liberties” in the first paragraph refer to
(a) The right to vote , not to obey and right to a job
(b) The right to vote and not to obey
(c) The rights of servants to disobey their master and the right of the master to punish them
(d) Women’s right to vote and earn money
Passage
During the past three generations, the diseases affecting western societies have undergone dramatic changes. Polio, diphtheria, tuberculosis, commonly known as TB, are vanishing; one injection of an antibiotic often cures deadly diseases such as pneumonia or syphilis, and so many mass killers have come under control that two-thirds of all death is now associated with the diseases of old age. Those who die young are more often than not victims of accidents, violence, or suicide.
These changes in health status are generally equated with the decrease in suffering and attributed to more or better medical care. Almost everyone believes that at least one of his friends would not be alive and well except for the skill of a doctor. But there is, in fact, no evidence of any direct relationship between this change in the pattern or nature of sickness on the one hand and the so-called progress of medicine on the other hand. These changes are the results of political technological changes. They are not related to the activities that require the preparation and status of doctors or the costly equipment in which doctors take pride. In addition, an increase in the number of new diseases in the last fifteen years are themselves the result of medical intervention. They are doctor-made or iatrogenic.
14) In the western societies, the occurrences of polio, diphtheria, and tuberculosis has
(a) increased
(b) completely stopped
(c) decreased
(d) continued without changes
15) More death are now associated with old age than in the past because
(a) iatrogenic diseases are spreading faster now
(b) deadly diseases affecting the young have been well controlled
(c) Accidents, violence and suicide that killed many youths in the past are now under control
(d) political and technological changes now take better care of the young than the old
16) The writer probably is arguing for
(a) stopping the practice of western medicines completely
(b) stopping the use of costly equipment and medicines
(c) rethinking about the successes and failures of the western medicines
(d) giving greater attention to new, iatrogenic diseases than to the old diseases such as polio , diphtheria and pneumonia
