Mark the letter A, B, C or D on your answer to indicate the correct answer to each of the question from 1 to 10.The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were Câused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920‟s and 1930‟s, nutrition became a science and the vitamin hunters replaced the microbe hunters.In the 1940‟s and 1950‟s, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage.You are aware that the enzymes hunters have been replaced by a new breed of hunters who are tracking genes – the blueprints for each of the enzymes – and are discovering the defective genes that Câuse inherited diseases – diabetes, cystic fibrosis. These gene hunters, or genetic engineers, use recombinant DNA technology to identify and clone genes and introduce them into bacterial cells and plants to create factories for the massive production of hormones and vaccines for medicine and for better crops for agriculture. Biotechnology has become a multibillion-dollar industry.In view of the inexorable progress in science, we can expect that the gene hunters will be replaced in the spotlight. When and by whom? Which kind of hunter will dominate the scene in the last decade of our century and in the early decades of the next? I wonder whether the hunters who will occupy the spotlight will be neurobiologists who apply the techniques of the enzyme and gene hunters to the functions of the brain. What to call them? The head hunters. I will return to them later.With which of the following statements would be the author be most likely to agree?

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.Prehistoric horses were far removed from the horses that Christopher Columbus brought on his ships during his second voyage to the New World. Although fossil remains of “dawn horses” have been excavated in several sites in Wyoming and New Mexico, these animal, which were biologically different from contemporary horses, had been extinct several millennia before onset of the Indian era. Although moviegoers visualize an Indian as a horse rider, Indians were not familiar with horses until the Spanish brought them to Mexico, New Mexico, Florida, and the West Indies in 1519. Those that escaped from the conquerors or were left behind became the ancestors of the wild horses that still roam the southwestern regions of the country. The Indian tribe scattered in the western plains began to breed horse about 1600.The arrival of the horse produced a ripple effect throughout the Great Plains as the Indians living there were not nomadic and engaged in rudimentary farming and grazing land hunting. Tracking stampeding herds of buffalo and elk on foot was not the best way to stock quantities of meat to adequately feed the entire tribe during the winter. However, mounted on horses, the hunting team could cover ground within a substantial distance from their camps and transport their game back to be roasted, dried into jerky, or smoke for preservation. The hunters responsible for tribe provisions stayed on the move almost continuously, replacing their earth-and-sod lodges with tepees. Horses carried not only their riders but also their possessions and booty. The Blackfoot Indians of the Canadian plains turned almost exclusive hunters, and the Crow split off from the mainstream Indian farming in favor of hunting. In fact, some of the Apache splinter groups abandoned agricultural cultivation altogether.The horse also drastically altered Indian warfare by allowing rapid maneuvering before, during, and after skirmishes. With the advent of the horse, the Apache, Arapahoe, and Cheyenne established themselves as territorial monopoly in the Plains. Because Indians did not have the wheel and had dragged their belongings from one settlement to another, horse also enabled them to become more mobile and expedient during tribal migration. In fact, the Cheyenne abolished the custom of discarding belongings and tepee skins simply because there were no means to transport them.It can be inferred from the passage that the arrival of horses in the Americas_____.

With the advent of the horse, the Apache, Arapahoe, and Cheyenne established themselves as territorial monopoly in the Plains. Because Indians did not have the wheel and had dragged their belongings from one settlement to another, horse also enabled them to become more mobile and expedient during tribal migration.

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.Prehistoric horses were far removed from the horses that Christopher Columbus brought on his ships during his second voyage to the New World. Although fossil remains of “dawn horses” have been excavated in several sites in Wyoming and New Mexico, these animal, which were biologically different from contemporary horses, had been extinct several millennia before onset of the Indian era. Although moviegoers visualize an Indian as a horse rider, Indians were not familiar with horses until the Spanish brought them to Mexico, New Mexico, Florida, and the West Indies in 1519. Those that escaped from the conquerors or were left behind became the ancestors of the wild horses that still roam the southwestern regions of the country. The Indian tribe scattered in the western plains began to breed horse about 1600.The arrival of the horse produced a ripple effect throughout the Great Plains as the Indians living there were not nomadic and engaged in rudimentary farming and grazing land hunting. Tracking stampeding herds of buffalo and elk on foot was not the best way to stock quantities of meat to adequately feed the entire tribe during the winter. However, mounted on horses, the hunting team could cover ground within a substantial distance from their camps and transport their game back to be roasted, dried into jerky, or smoke for preservation. The hunters responsible for tribe provisions stayed on the move almost continuously, replacing their earth-and-sod lodges with tepees. Horses carried not only their riders but also their possessions and booty.

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 questionsFish that live on the sea bottom benefit by being flat and hugging the contours. There are two very different types of flatfish and they have evolved in very separate ways. The skates and rays, relatives of the sharks have become flat in what might be called the obvious way. Their bodies have grown out sideways to form great “wings” They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely fish such as plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole vertically flattened bodies as swimming surfaces, which undulate through the water as they move. Therefore when * their ancestors migrated to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless - In evolution this problem was solved by the lower eye “moving” around the other side. We see this process of moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion, so that one eye for instance the left, moves over the top of the head upwards, an old Picasso - like vision. Incidentally, some species of 20 flatfish settle on the right side, others on the left, and others on either side.Question:According to the passage, the ability of a bony flatfish to move its eyes around is______
