A Japanese construction company plans to create a huge independent city-state, akin to the legendary Atlantis, in the middle of the Pacific Ocean. The city, dubbed “Marinnation”, would have about one million inhabitants, two airports, and possibly even a space port. Marinnation, if built, would be a separate country but could serve as a home for international organisations such as the United Nations and the World Bank. Aside from the many political and social problems that would have to be solved, the engineering task envisaged is monumental. The initial stage requires the building of a circular dam eighteen miles in diameter attached to the sea bed in a relatively shallow place in international waters. Then, several hundred powerful pumps, operating for more than a year, would suck out the sea water from within the dam. When empty and dry, the area would have a city constructed on it. The actual land would be about 300 feet below the sea level. According to designers, the hardest task from an engineering point of view would be to ensure that the dam is leak proof and earthquake proof. If all goes well, it is hoped that Marinnation could be ready for habitation at the end of the second decade of the twenty-first century. Whether anyone would want to live in such an isolated and artificial community, however, will remain an open question until that time. 

According to the text, Marrination, when built, will be a(an)__________ city.

Until recently, most American entrepreneurs were men. Discrimination against women in business, the demands of caring for families, and lack of business training had kept the number of women entrepreneurs small. Now, however, businesses owned by women account for more than $40 billion in annual revenues, and this figure is likely to continue rising throughout the 1990s. As Carolyn Doppelt Gray, an official of the Small Business Administration, has noted, "The 1970s was the decade of women entering management, and the 1980s turned out to be the decade of the woman entrepreneur". What are some of the factors behind this trend? For one thing, as more women earn advanced degrees in business and enter the corporate world, they are finding obstacles. Women are still excluded from most executive suites. Charlotte Taylor, a management consultant, had noted, "In the 1970s women believed if they got an MBA and worked hard they could become chairman of the board. Now they've found out that isn't going to happen, so they go out on their own". In the past, most women entrepreneurs worked in "women's" fields: cosmetics and clothing, for example. But this is changing. Consider ASK Computer Systems, a $22-million-a-year computer software business. It was founded in 1973 by Sandra Kurtzig, who was then a housewife with degrees in math and engineering. When Kurtzig founded the business, her first product was software that let weekly newspapers keep tabs on their newspaper carriers-and her office was a bedroom at home, with a shoebox under the bed to hold the company's cash. After she succeeded with the newspaper software system, she hired several bright computer-science graduates to develop additional programs. When these were marketed and sold, ASK began to grow. It now has 200 employees, and Sandra Kurtzig owns $66.9 million of stock. Of course, many women who start their own businesses fail, just as men often do. They still face hurdles in the business world, especially problems in raising money; the banking and finance world is still dominated by men, and old attitudes die hard. Most businesses owned by women are still quite small. But the situation is changing; there are likely to be many more Sandra Kurtzigs in the years ahead.

What is the main idea of this passage?

A considerable body of research has demonstrated a correlation between birth order and aspects such as temperament and behavior , and some psychologists believe that birth order significantly affects the development of personality. Psychologist Alfred Adler was a pioneer in the study of the relationship between birth order and personality. A key point in his research and in the hypothesis that he developed based on it was that it was not the actual numerical birth position that affected personality; instead, it was the similar response s in large numbers of families to children in specific birth order positions that had an effect. For example, first-borns, who have their parents to themselves initially and do not have to deal with siblings in the first part of their lives, tend to have their first socialization experiences with adults and therefore tend to find the process of peer socialization more difficult. In contrast, later-born children have to deal with siblings from the first moment of their lives and therefore tend to have stronger socialization skills.

 Numerous studies since Adler’s have been conducted on the effect of birth order and personality. These studies have tended to classify birth order types into four different categories: first-born, second-born and/or middle, last, and only child.

 Studies have consistently shown that first-born children tend to exhibit similar, positive and negative personality traits. First-borns have consistently been linked with academic achievement in various studies; in one study, the number of National Merit scholarship winners who are first-borns was found to be equal to the number of second-and third-borns combined. First-borns have been found to be more responsible and assertive than those born in other birth-order positions and tend to rise to positions of leadership more often than others; more first-borns have served in the U.S. Congress and as U.S. presidents than have those born in other birth-orderpositions. However, studies have shown that first-borns tend to be more subject to stress and were considered problem children more often than later- borns.

 Second-born and/or middle children demonstrate markedly different tendencies from first-borns. They tend to feel inferior to the older child or children because it is difficult for them to comprehend that their lower level of achievement is a function of age rather than ability, and they often try to succeed in areas other than those in which their older sibling or siblings excel. They tend to be more trusting, accepting, and focused on others than the more self-centered first-borns, and they tend to have a comparatively higher level of success in team sports than do first-borns or only children, who more often excel in individual sports.

 The last-born child is the one who tends to be the eternal baby of the family and thus often exhibits a strong sense of security. Last- borns collectively achieve the highest degree of social success and demonstrate the highest levels of self-esteem of all the birth-order positions.They often exhibit less competitiveness than older brothers and likely to take part in less competitive group games or in social organizations such as sororities and fraternities.

 Only children tend to exhibit some of the main characteristics of first - borns and some of the characteristics of last - borns. Only children tend to exhibit the strong sense of security and self - esteem exhibited by lastborns while, like first - borns, they are more achievement oriented and more likely than middle - or last - borns to achieve academic success. However, only children tend to have the most problems establishing close relationships and exhibit a lower need for affiliation than other children.
