Lights on, lights off. Just the quick flick of a finger on a simple switch brightens or darkens the room. That power is the envy of geneticists. They long for similar ease in activating and de-activating genes in cultured cells and transgenic animals. In recent years, these scientists have gained some measure of control by using chemical compounds, including the antibiotic tetracycline, to govern genes in cells and mice. The insect hormone ecdysone may provide the most effective gene switch yet, suggest investigators from the Howard Hughes Medical Institute at the Salk Institute for Biological Studies in La Jolla, Calif., and the University of California, San Diego. To support that contention, the group has made mammalian cells and strains of mice with genes that are activated when ecdysone reaches them. With such a system, researchers should be able to examine the importance of the timing of gene activity, particularly during an organism's development. Since the hormone has no adverse effect on mammalian cells, ecdysone-based switches may ultimately provide a non-toxic way to control the therapeutic genes inserted into humans. "It looks pretty promising. It seems to work as well as, if not better than, the tetracycline system," says Janet Rossant, a developmental biologist at the Mount Sinai Hospital in Toronto.

According to the Big Bang theory, the universe began in a giant explosion. Ever since, the cosmos has ballooned in size, carrying galaxies further apart. But gravity slows that expansion and determines the fate of the universe. If gravity is weak, the universe will remain open, expanding forever. However, if the universe contains sufficient mass, it will eventually close in on itself: Gravity will halt cosmic expansion, crashing galaxies together in a Big Crunch. In a third scenario, the universe is delicately balanced between expansion and collapse, possessing just enough gravity to halt inflation without contracting. Although cosmologists have by no means reached a consensus, recent evidence suggests that the cosmos will grow indefinitely. An analysis of some of the deepest cosmic images ever taken supports this idea. In the new findings, presented last week in Liverpool, England, at the Royal Astronomical Society's National Astronomy Meeting, Thomas Shanks, Nigel Metcalfe, Ana Campos, and their colleagues at the University of Durham in England observe that gravity curves space in such a way that the volume of universe within a given radius from Earth is greater for an open universe than a closed one. The number of galaxies in that volume will therefore also be greater, so counting them could indicate the nature of the universe. So far so good. But the difference in volume between an open and a closed universe becomes significant only when astronomers consider a chunk of universe containing distant objects. Unfortunately, galaxies located far from Earth are often too dim to detect visually.
31. The Big Bang theory maintains that since the universe began
a. the cosmos has remained the same size. b. there have been giant explosions in the cosmos. c. the cosmos has increased in size. d. a part of the cosmos carries galaxies.
32. The third scenario sees the universe
a. as being too delicate to balance. b. as having enough of a gravitational pull to prevent it shrinking. c. as having sufficient gravity to allow it to expand further. d. as being ready to collapse.
33. Analysis of some of the deepest cosmic images ever taken suggests
a. that scientists will reach a consensus. b. an ever expanding cosmos. c. indefinite results. d. that scientists will by no means agree.
34. The new findings referred to maintain that
a. gravity increases volume of space. b. the radius from Earth is opening up. c. gravity closes the universe. d. space is curved by gravity.
35. What problem faces astronomers who are studying the cosmos?
a. Distant galaxies are often not bright enough to locate. b. Comparing open and closed galaxies is impossible. c. Astronomers have not been able to observe distant objects. d. Chunks of the universe do not contain distant objects.

Finding the right male to mate with is not a simple matter - not even for a female guppy. Oh sure, she could go just for good looks: a guy's size, tail length, and color, for example. Some of these physical preferences are so important to reproduction that they appear to be hard-coded into a guppy's genetic heritage. Yet female guppies do not depend solely on those factors for choosing a mate, notes Lee Alan Dugatkin of the University of Louisville in Kentucky. A few years ago, he found that a female guppy often imitates the mating choices of other females. In the April 2 PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES, he reports on the first systematic look at whether appearance or cultural cues dominate this fishy issue. He finds that female guppies, which normally prefer a mate with lots of orange, are easily persuaded to pick a male with less orange coloration if they observe another female mating with him. In special cases, looks can override those cultural cues. "When the males are dramatically different (in amount of color), females don't copy," says Dugatkin. If one of two available males has at least 40 percent more orange color than the other, a female will mate with him regardless of the other females' actions. Dugatkin suggests that examining the behavior of guppies may provide insight into how to study inherited and cultural factors than govern mating choices of women. 31. Which of the following is not characteristic that may determine a female guppy's choice of a
a. Its coloration b. How fast it swims c. Its length d. How big it is
32. Studies conducted a few years ago indicate that a female guppy's choice of a prospective mate
a. how soon it sees the male mating. b. which females the male attracts. c. what other females do when choosing a mate. d. where other females choose to mate.
33. Which of the following do more recent studies of the mating behavior of female guppies reveal?
a. They do not rely entirely on a male's appearance. b. They always reject males with less orange coloration. c. They remain faithful to a single male. d. They are not attracted by the amount of orange in males.
34. The most recent findings indicate that . . .
a. the desire of a female guppy to imitate the behavior of other females overrides all other
b. cultural cues always determine a female's choice of a mate. c. appearance may be a decisive factor in a guppy's choice of a mate. d. dramatically different behavior by males may affect a female's choice.
35. Dugatkin believes that his studies may answer questions concerning . . .
a. why women choose a particular mate. b. how women inherit cultural factors. c. the insights we already have into the mating choices of women. d. only the inherited behavior of women.

One hundred and fifteen thousand years ago, the Earth began a descent from the warmth of the last interglacial to the frigid climate of the last ice age. What began as a period with air temperatures similar to the present or perhaps slightly warmer, had declined by 21,000 years ago to a state 7 - 10 degrees Centigrade colder than today. High-latitude temperatures were at least 15 degrees Centigrade colder, and ice sheets more than 1 km thick covered most of North America and large portions of Eurasia above 55 degrees North. The mechanism commonly accepted as initiating the growth of these massive continental ice sheets is the reduction of summertime solar radiation at high latitudes, resulting from cyclical variations in the orbit of the Earth. But many global climate modelling studies have found that the reduction that occurred 115 kyr ago does not, by itself, yield however, climate model experiments reported by Gallimore and Kutzbach show that changing vegetation patterns, specifically the spread of tundra, may have played a prominent role in this reversal of fortunes for the global climate. 31.

The Hutterites call themselves the human version of a bee colony. Members of this Christian sect, who first settled in the United States in the 19th century, shun personal gain and pour their efforts into a well-oiled collective enterprise. Hutterite ideology stresses the shared fate of the group and warns against the sin of selfishness. Anyone who withholds help from others in need, turns lazy, or otherwise undermines community health draws stern reprimands from church elders. Failure to heed these warnings results in forced exile. Hutterite leaders are elected democratically and undergo a long probationary period before acquiring full power. When a colony grows too large – which is not uncommon, as the Hutterites have long experienced high birth rates – it sorts into two groups of equal size, skill, and compatibility. A lottery determines which group stays and which moves to a new location. Such practices sound downright strange to the average suburbanite or city dweller. Indeed, end-of-the-millennium Western societies seem to spawn far more self-absorption than sacrifice for any “greater good.” But the bee like tactics of Hutterite colonies highlight an evolved human capacity for thinking in groups and advancing group interests, even at the expense of personal strivings, asserts David Sloan Wilson, an evolutionary biologist at the State University of New York at Binghamton. “Groups can be functional units in their own right, and individuals sometimes behave more like organs than like organism,” Wilson contends. “As a result, altruism is a common feature of both human and biological nature.” 31. Hutterites are characterized by their . . .
a. pride. b. greed. c. selflessness d. individualism
32. A Hutterite who displays laziness and ignores warnings to reform . . .
a. is made to leave the group. b. turns selfish. c. reprimands church elders. d. shares the fate of the group.

a. They have to elect deputies. b. They have to prove themselves worthy. c. They are chosen by the group. d. They do not automatically assume full power.
34. What accounts for the division of many Hutterite colonies?
a. The skills of their members become unequal. b. The members are unable to live together peacefully. c. Too many immigrants join the colony. d. New births within the colonies swell their population.
35. Wilson maintains that Hutterite practices . . .
a. mirror the average contemporary Western society. b. reflect how strong an effect altruism can have on our actions. c. prove that personal striving is an overwhelming force. d. have a high capacity for self-absorption.

The closest relatives of the hoatzin, a blue-faced South American bird, are neither turkeys nor chickens, as many bird experts had assumed; they are cuckoos, a new study concludes. The finding shows that 220 years of research on the hoatzin was no wild-goose chase. Since describing the bird, Opisthocomos hoazin, in 1776, ornithologists have had problems pinpointing its closest kin, as the hoatzin looks and acts son unlike other birds. It digests its food, for example, the way a cow does, in a chamber above its stomach. Scientists have disagreed most recently over whether hoatzins are closer to cuckoos or to galliforms such as pheasants, chickens, and turkeys. Galliforms are among the most ancient birds, while cuckoos appeared more recently. The scientists conclude, however, that the hoatzin belongs next to the cuckoo's nest, not in it, because of the species' DNA and structural differences. For example, the cuckoo has two forward and two backward toes, while the hoatzin has three forward and one backward. Indeed, the team recommends placing hoatzins in their own suborder, Opisthocomi, in the Cuculiformes order. All other members of the order, such as cuckoos, should then come under the suborder Cuculi. The findings serves as an "eye-opening example of how molecular data can resolve phylogenic relationship, "says S. Blair Hedges of Pennsylvania State University in University Park. Morphology "has tricked people for a long time." 31. A recent study on the hoatzin . . .
a. has confirmed previous assumptions. b. has taken 220 years of research. c. has linked it to the cuckoo family. d. has concluded that it is a relative of the wild goose.
a. the way it looks and acts. b. the food it consumes. c. the way it eats. d. its closest kin.
33. The arrival of Galliforms on our planet . . .
a. preceded the appearance of Cuculiformes. b. succeeded the appearance of Cuculiformes. c. occurred simultaneously with that of the Cuculiformes. d. introduced species such as the cuckoo.

a. quotes a dissimilarity in the DNA of the two birds. b. is based on their foot structure. c. presents the differences in the structure of their nests. d. notes the differences in the number of toes each bird has.
35. If adopted, the recommendations of the research team would . . .
a. remove the order of Cuculiformes. b. create two suborders of Cuculiformes. c. place all Cuculiformes under the suborder Cuculi. d. place more species under the suborder Opisthocomi.

Certain gases in the atmosphere allow visible light to pass through, but they block much of the heat reflected from the Earth's surface - in the same fashion as the glass windows in a greenhouse. Without this greenhouse effect, worldwide temperatures would be lower by 35 degrees Celsius, most of the oceans would freeze, and life would cease or be totally altered. According to the theory of global warming, an increase in greenhouse gases in the atmosphere will produce unacceptable temperature increases. A doubling of the volume of gases, for example, would cause temperatures to go up by 1.5 degrees C or more, a phenomenal change by historical standards. The most dramatic consequence of the warming would be a rise in sea level from the melting of the polar ice caps, a rise that the Environmental Protection Agency projects to be 20 feet as early as the year 2000 - sufficient to submerge large parts of coastal cities. Global warming would result in profound shifts in agriculture and may, as some have suggested, hasten the spread of infection diseases. Aside from water vapor, the principal greenhouse gases are carbon dioxide, resulting from the burning of fossil fuels; methane, produced by the breakdown of plant materials by bacteria; nitrous oxide, produced during the burning of fossil fuels and by the decomposition of chemical fertilizers and by bacterial action; and chlorofluorocarbons, used for industrial and commercial purposes, such as air conditioning. Of these, carbon dioxide is the most important. The atmospheric concentration of this gas was 280 parts per million before the Industrial Revolution; with the increasing use of fossil fuels, the figure is currently 350 parts. The idea of global warming gained support as temperatures soared to record levels in the 1980s' but there are several problems with the theory, including doubts about the reliability of the temperature record. Despite this, a majority of climatologists feel that a risk of global warming exists, although there is much disagreement concerning the extent and the timing. At the 1992 U.N. Conference on Environment and Development, over 150 nations signed the U.N. Convention on Climate Change, which pledges signatories to control emissions of greenhouse gases. 31.

Analysts expect personal computers to reign once again over the big-ticket gift market this holiday season. Sales may get an additional boost as people with home offices rush to buy PCs by the end of the tax year. Forty percent of these new acquisitions in the United States at least, will replace existing slow or obsolete systems, according to Nikki and David Goldberg, authors of Choose to Reuse. While some of the castoffs will be passed on to other family members or used for game and educational software, most are expected to be mothballed - relegated to closets, the basement, or a corner of the guest room. Indeed, millions of PCs worldwide will have been retired from service already. Although these units are too slow or limited to handle the computer enthusiast's burgeoning demands, most still have a lot of data-processing power left. It's because consumers recognize this latent value that they've been squirreling their discards away instead of putting them out with the trash. When commercial users upgrade their PCs, even the trash isn't an option for the old ones. Because of the high content of heavy metals in computers, they qualify as hazardous waste, requiring costly, regulated disposal. Increasingly, therefore, both individual and corporate computer users have begun looking for new homes for this hardware. Though not widely visible, many firms have sprung up to accept these orphans. Propelled by options for recycling cyberjunk. 31. As the holiday season approaches, personal computers are expected . . .
a. to become a popular gift item. b. to replace other gift items which have been popular until now. c. to fall in popularity. d. to retain their popularity as high-priced gift items.
32. What will be the fate of most of the systems which will be replaced?
a. Other family members will be allowed to use them. b. They will be used to decorate various rooms. c. They will be placed in mothballs. d. They will be stored away.
33. Why haven't these units been thrown away?
a. They can still be of use. b. They are too slow to handle the demands of computer enthusiasts. c. Their applications are limited. d. They place burgeoning demands on computer enthusiasts.

Using explosive blasts and large vibrating trucks, an international team of seismologists has peered far below Russia's Ural Mountains to find out why they resemble no other mountain chain. Reaching unprecedented depths of 150 to 200 kilometers, the seismic imaging equipment illuminated structures all the way down to the base of the lithosphere - Earth's outer shell. "This is certainly the most ambitious effort ever undertaken in terms of imaging the lithosphere," says James H. Knapp of Cornell University. The project teamed U.S. researchers with scientists from Germany, Russia, and Spain. To peek under Earth's skin, Knapp and his colleagues created small artificial earthquakes. The seismic waves raced down into the lithosphere and bounced off hidden structures, such as faults or folds. The seismologists focused their study on the Urals because the 3,000-kilometer-long chain is frozen in mid-evolution. The range formed when Asia smashed into Europe between 600 million and 300 million years ago, at about the same time that North America collided with Africa, building the Appalachian Mountains. The Appalachians entered old age when North America separated from Africa, tearing apart the lithosphere and causing the once-towering mountain range to collapse. The Urals have remained intact because Asia never separated from Europe. "This is an important time to reexamine how mountain belts evolve, because we see in the Urals an example of one that didn't," says Knapp. 31. The international team of seismologists conducted their experiments . . .
a. to explain the unprecedented depth of the Urals. b. to discover more about the uniqueness of the Urals. c. to learn more about he world's mountain chains. d. to search for hidden structures.
32. Previous attempts at imaging the lithosphere . . .
a. have been more successful. b. have not attempted so much. c. have gone to much greater depths. d. have triggered off small earthquakes.
33. The formation of the Urals occurred at about the same time as . . .
a. the creation of Asia. b. the separation of Asia from Europe. c. the collision between North America and Africa. d. the collapse of the Appalachians.
34. We can assume that the Appalachians Mountains . . .
a. were much higher in the past. b. were once a part of Africa. c. were formed when North America and Africa separated. d. have remained intact since they were formed.
a. have not followed the usual evolutionary pattern of most mountain chains. b. Have suffered the same fate as the Appalachians c. Have undergone several phases of growth and collapse. d. Have now entered there old age.

Nearsightedness, or myopia, results when the eye becomes too long from front to back. Ordinarily, light passes through the corneal lens and focuses images on the rear portion of the eye, known as the retina. The myopic eye is so long that the images focus in front of the retina, making objects at a distance blurry. In the farsighted, or hyperopic, eye, the eye is short; images focus behind the retina, causing nearby objects to blur. Animal and human babies usually begin life slightly hyperopic. As they grow, their eyes lengthen until all images fall perfectly on the retina, a process called emmetropization. By the first grade, nearly all children have perfect vision. Researchers do not know what mechanisms spur the eye to grow to a length that matches flawlessly the eye's optics. It takes work to see at varying distances, even when vision is "perfect." Reading, for instance, requires tiny muscles in the eye to accommodate for the short focus by making the lens rounder. When this retina, whether as the result of myopia or hyperopia, corrective lenses can be recruited to do the work. Increasingly, people in developed countries have come to rely on corrective lenses. Sometime between starting school with perfect vision and beginning high school, up to 50 percent of kids in the United States become myopic. In places like Taiwan and Hong Kong, where kids typically study 10 to 12 hours per day. 70 percent of older students need to squint to see the blackboard. 31. The condition called myopia develops when . . .
a. the distance between the lens and the retina is increased. b. the lens of the eye can no longer focus. c. light is unable to pass through the corneal lens. d. light focuses on the retina.
32. The process called emmetropization . . .
a. eventually produces myopia in first graders. b. produces blurry images on the retina. c. slowly corrects the initial condition of hyperopia which most newborn babies have. d. corrects the myopia that most newborn babies have.

a. are perfectly understood. b. remain a mystery. c. have been fully explained. d. have never concerned researchers.
34. A corrective lens is used to ensure that . . .
a. images fall in focus on the retina. b. the corneal lens becomes rounder. c. distances do not vary. d. tiny muscles in the eye work.
35. Indications are that myopia among high school students . . .
