II. GUIDED CLOZE TEST: Choose the word or phrase that best fits each space in the following passage.
Scientists have been investigating chimpanzee culture for several decades, but too often their studies contained a crucial (01) _____. Most attempts to document cultural diversity among chimpanzees have (02)_____ solely on officially published (03) _____ of the behaviors recorded at each research site. But this approach probably (04) _____ a good deal of cultural variation for three reasons. First, scientists typically don't publish a(n) (05) _____ list of all the activities they do not see at a parular location. Yet this is exactly what we need to know-which behaviors were and were not observed at each site. Second, many reports describe chimpanzee behaviors without saying (06) _____ common they are; with- out this information, we can't determine whether a parular action was a once-in-a-lifetime aberration or a routine event that should be considered part of the animals' culture. Finally, researchers' descriptions of potentially significant chimpanzee behaviors frequently lack (07) _____ detail, making it difficult for scientists working at other spots to record the presence or absence of the activities. To (08) _____ these problems, the two of us decided to take a new approach. We asked field researchers at each site for a list of all the behaviors they suspected were local traditions. With this information in hand, we pulled together a comprehensive list of 65 (09) _____ for cultural behaviors. Then we distributed our list (10) _____ the team leaders at each site. In consultation with their colleagues, they classified each behavior (11) _____ of its occurrence or absence in the chimpanzee community (12) _____. The key categories were customary behavior (occurs in most or all of the able-bodied members of at least one age or sex class, such as all adult males), habitual (less common than customary but occurs repeatedly in several individuals), present (seen at the site but not habitual), absent (never seen), and unknown. Our inquiry concentrated on seven sites with chimpanzees habituated to human onlookers; all told, the study compiled a total of more than 150 years of chimpanzee observation. The behavior patterns we were parularly interested in, of course, were those absent in at least one community, yet habitual or customary in at least one other; this was our criterion for denoting any behavior a cultural variant. (Certain behaviors are absent for specific local reasons, however, and we excluded them from consideration. For example, although chimpanzees at Bossou scoop tasty algae from pools of water with a sk, chimpanzees else- where don't do this, simply because algae are not present.) The extensive survey turned up (13) _____ 39 chimpanzee (14) _____ of behavior that should be labeled as cultural variations, including (15) _____ forms of tool use, grooming techniques and courtship gambits, several of which are illustrated throughout this arle. This cultural richness is far in excess of anything known for any other species of animal

III. READING: | ||||
Alfred Nobel was born in Stockholm on October 21,1833. His father, Immanuel Nobel, was an engineer and inventor who built bridges and buildings in Stockholm. In connection with his construction work, Immanuel Nobel also experimented with different techniques for blasting rocks. Alfred's mother, born Andriette Ahlsell, came from a wealthy family. Due to misfortunes in his construction work caused by the loss of some barges of building material, Immanuel Nobel was forced into bankruptcy the same year Alfred Nobel was born. In 1837 Immanuel Nobel left Stockholm and his family to start a new career in Finland and in Russia. To support the family, Andriette Nobel started a grocery store which provided a modest income.
Meanwhile, Immanuel Nobel was successful in his new enterprise in St. Petersburg, Russia. He started a mechanical workshop which provided equipment for the Russian army, and he also convinced the Tsar and his generals that naval mines could be used to block enemy naval ships from threatening the city. The naval mines designed by Immanuel Nobel were simple devices consisting of submerged wooden casks filled with gunpowder. Anchored below the surface of the Gulf of Finland, they effectively deterred the British Royal Navy from moving into firing range of St Petersburg during the Crimean War (1853-1856). Immanuel Nobel was also a pioneer in arms manufacture and in designing steam engines.
Successful in his industrial and business ventures, Immanuel Nobel was able, in 1842, to bring his family to St.Petersburg. There, his sons were given a first class education by private teachers. The training included natural sciences, languages and literature. By the age of 17, Alfred Nobel was fluent in Swedish, Russian, French, English and German. His
primary interests were in English literature and poetry as well as in chemistry and physics. Alfred’s father, who wanted his sons to join his enterprise as engineers, disd Alfred’s interest in poetry and found his son rather introverted. In order to widen Alfred’s horizons, his father sent him abroad for further training in chemical engineering. During a two-year period Alfred Nobel visited Sweden, Germany, France and the United States. In Paris, the city he came to best, he worked in the private laboratory of Professor T. J.
Pelouze, a famous chemist. There he met the young Italian chemist Ascanio Sobrero who, three years earlier, had invented nitroglycerine, a highly explosive liquid. Nitroglycerine was produced by mixing glycerine with sulfuric and nitric acid, it was considered too dangerous to be of any pracal use. Although its explosive power greatly exceeded that of gunpowder, the liquid would explode in a very unpredictable manner if subjected to hesft and pressure. Alfred Nobel became very interested in nitroglycerine and how it could be put to pracal use in construction work. He also realized that the safety problems had to be solved and a method had to be developed for the controlled detonation of nitroglycerine. In the United States he visited John Ericsson, the Swedish American engineer who had developed the screw propeller for ships. In 1852 Alfred Nobel was asked to come back and work in the family enterprise which was booming because of its deliveries to the Russian army. Together with his father he performed experiments to develop nitroglycerine as a commercially and technically useful explosive.
The market for dynamite and detonating caps grew very rapidly and Alfred Nobel also proved himself to be a very skillful entrepreneur and businessman. By 1865 his factory in Krummel - near Hamburg, Germany was exporting nitroglycerine explosives to other countries in Europe, America, and Australia. Over the years he founded factories and laboratories in some 90 different places in more than 20 countries. Although he lived in Paris much of his life, he was constantly traveling. Victor Hugo at one time described him as “Europe’s richest vagabond”. When he was not traveling or engaging in business activities, Nobel himself worked intensively in his various laboratories, first in Stockholm and later in Germany, Scotland, France, Karlskoga, Sweden, and Italy. He focused on the development of explosives technology as well as other chemical inventions, including such materials as synthe rubber, leather, and silk. By the time of his death in 1896. he had 355 patents.
Intensive work and travel did not leave much time for a private life. At the age of 43 he was feeling an old man. At this time he advertised in a newspaper “Wealthy, highly-educated elderly gentleman seeks lady of mature age, versed in languages, as secretary and supervisor of household.” The most qualified applicant turned out to be an Austrian woman. Countess Bertha Kinsky. After working a very short time for Nobel, she decided to return to Austria to marry Count Arthur von Suttner. In spite of this Alfred Nobel and Bertha von Suttner re¬mained friends and kept writing letters to each other for decades. Over the years Bertha von Suttner became increasingly crial of the arms race. She wrote a famous book, Lay Down Your Arms and became a prominent figure in the peace movement.
Alfred Nobel died in San Remo, Italy, on December 10,1896. When his will was opened it came as a surprise that his fortune was to be used for Prizes in Physics, Chemistry, Physiology or Medicine, Literature and Peace. The executors of his will were two young engineers, Ragnar Sohlman and Rudolf Liljequist. They set about forming the Nobel Foundation as an organization to take care of the financial assets left by Nobel for this purpose and to coordinate the work of the Prize-Awarding Institutions. This was not without its difficulties since the will was contested by relatives and questioned by authorities in various countries.
