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 responses 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-bom 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 - order positions. 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 firstborns. 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 sisters and are more 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 selfesteem exhibited by last-borns 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.

Dịch nghĩa:
“Một lượng nghiên cứu đáng kể đã chứng minh mối tương quan giữa thứ tự sinh và các yếu tố như tính khí và hành vi, và một số nhà tâm lý học tin rằng thứ tự sinh có ảnh hưởng đáng kể đến sự phát triển nhân cách. Nhà tâm lý học Alfred Adler là một người tiên phong trong việc nghiên cứu mối quan hệ giữa thứ tự sinh và nhân cách. Một điểm chính trong nghiên cứu của ông và giả thuyết mà ông phát triển dựa trên nghiên cứu này là không phải thứ tự sinh số học thực tế ảnh hưởng đến nhân cách; thay vào đó, chính là những phản ứng tương tự trong số lượng lớn các gia đình đối với trẻ em ở các vị trí thứ tự sinh cụ thể mới có tác động. Ví dụ, những đứa con đầu lòng, ban đầu có bố mẹ hoàn toàn chú ý đến mình và không phải đối phó với anh chị em trong phần đầu đời, thường có những trải nghiệm xã hội hóa đầu tiên với người lớn và do đó thường gặp khó khăn hơn trong quá trình xã hội hóa với bạn bè đồng trang lứa. Ngược lại, những đứa con sinh sau phải đối mặt với anh chị em từ khi chào đời và do đó thường có kỹ năng xã hội hóa mạnh hơn.
Nhiều nghiên cứu kể từ thời của Adler đã được tiến hành về ảnh hưởng của thứ tự sinh đến nhân cách. Những nghiên cứu này thường phân loại các kiểu thứ tự sinh thành bốn nhóm khác nhau: con đầu lòng, con thứ hai và/hoặc con giữa, con út, và con một.
Các nghiên cứu đã liên tục chỉ ra rằng những đứa con đầu lòng có xu hướng thể hiện các đặc điểm nhân cách tương tự, cả tích cực và tiêu cực. Những đứa con đầu lòng liên tục được liên kết với thành tích học tập trong nhiều nghiên cứu; trong một nghiên cứu, số lượng người đạt học bổng National Merit là con đầu lòng được phát hiện bằng với số lượng con thứ hai và con thứ ba cộng lại. Những đứa con đầu lòng được phát hiện là có trách nhiệm hơn và quyết đoán hơn những đứa trẻ sinh ra ở các vị trí thứ tự sinh khác và có xu hướng thăng tiến lên các vị trí lãnh đạo thường xuyên hơn; nhiều người con đầu lòng đã phục vụ trong Quốc hội Hoa Kỳ và làm tổng thống Hoa Kỳ hơn những người sinh ra ở các vị trí thứ tự sinh khác. Tuy nhiên, các nghiên cứu đã chỉ ra rằng những đứa con đầu lòng có xu hướng bị căng thẳng nhiều hơn và thường được coi là trẻ có vấn đề hơn so với những đứa con sinh sau.
Những đứa con thứ hai và/hoặc con giữa thể hiện các xu hướng khác biệt rõ rệt so với những đứa con đầu lòng. Chúng thường cảm thấy kém cỏi hơn so với anh chị lớn hơn vì khó có thể hiểu rằng mức độ thành công thấp hơn của chúng là do tuổi tác chứ không phải khả năng, và chúng thường cố gắng thành công ở các lĩnh vực khác với những lĩnh vực mà anh chị em lớn hơn của chúng xuất sắc. Chúng có xu hướng tin tưởng, dễ chấp nhận, và tập trung vào người khác hơn so với những đứa con đầu lòng tự lấy mình làm trung tâm, và chúng có xu hướng thành công cao hơn trong các môn thể thao đồng đội so với những đứa con đầu lòng hoặc con một, những người thường xuất sắc hơn trong các môn thể thao cá nhân.
Những đứa con út là những đứa trẻ có xu hướng trở thành em bé mãi mãi trong gia đình và do đó thường thể hiện cảm giác an toàn mạnh mẽ. Những đứa con út tập thể đạt được mức độ thành công xã hội cao nhất và thể hiện mức độ tự trọng cao nhất trong tất cả các vị trí thứ tự sinh. Chúng thường ít cạnh tranh hơn so với anh chị lớn hơn và có xu hướng tham gia vào các trò chơi nhóm ít cạnh tranh hơn hoặc các tổ chức xã hội như hội nữ sinh và hội nam sinh.
Những đứa con một có xu hướng thể hiện một số đặc điểm chính của những đứa con đầu lòng và một số đặc điểm của những đứa con út. Những đứa con một có xu hướng thể hiện cảm giác an toàn và tự trọng mạnh mẽ như những đứa con út trong khi, giống như những đứa con đầu lòng, chúng có định hướng đạt thành tích hơn và có khả năng thành công học tập cao hơn so với những đứa con giữa hoặc con út. Tuy nhiên, những đứa con một thường gặp nhiều vấn đề nhất trong việc thiết lập các mối quan hệ thân thiết và thể hiện nhu cầu liên kết thấp hơn so với những đứa trẻ khác.”

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 28 to 34.
It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species' death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food Resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.
The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time - a mass extinction. One of the best-known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago. When approximately 95 percent of all species died, mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.
One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. This periodic extinction might be due to intersection of the Earth’s orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species’ survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random events.
