多选题A program instituted in a particular state allows parents to prepay their children's future college tuition at current rates. The program then pays the tuition annually for the child at any of the state's public colleges in which the child enrolls. Parents should participate in the program as a means of decreasing the cost for their children's college education. Which of the following, if true, is the most appropriate reason for parents not to participate in the program? A. The parents are unsure about which public college in the state the child will attend. B. The amount of money accumulated by putting the prepayment funds in an interest-bearing account today will be greater than the total cost of tuition for any of the public colleges when the child enrolls. C. The annual cost of tuition at the state's public colleges is expected to increase at a faster rate than the annual increase in the cost of living. D. Some of the state's public colleges are contemplating large increases in tuition next year. E. The prepayment plan would not cover the cost of room and board at any of the state's public colleges.

多选题Water beetles have a number of adaptations that make them able to live in water rather than on land as their countless beetle cousins do. Their spiracles open and close to take in air when they are on the surface and keep water out when they are underwater. Whirligig beetles have a clever division in their eyes that allows them to see above and below the surface at the same time. A number of water beetles, especially those that dive to find prey, trap and carry air bubbles with them on their abdomens, much as scuba divers carry air in their oxygen tanks. The legs of water beetles differ from those of their landlubber cousins. Often they are covered with fringelike hairs that help them speed across the water"s surface. Like all beetles, water beetles are capable of flight, but they usually use this skill only to escape predators or to move from puddle to pond.

多选题The pharmaceutical company insisted that its testing of new drugs was quite ______, more rigorous than the industry standard.

多选题The excessive number of safety regulations that the federal government has placed on industry poses more serious hardships for big businesses than for small ones. Since large companies do everything on a more massive scale, they must alter more complex operations and spend much more money to meet government requirements. Which of the following, if true, would most weaken the argtument above? A. Small companies are less likely than large companies to have the capital reserve for improvements. B. The operations of small companies frequently rely on the same technologies as the operations of large companies. C. Safety regulation codes are uniform, established without reference to size of company. D. Large companies typically have more of their profits invested in other business than do small companies. E. Large companies are in general more likely than small companies to diversity the markets and products.

多选题Analysis of prehistoric air trapped in tiny bubbles beneath the polar ice sheets and of the composition of ice surrounding those bubbles suggests a correlation between carbon dioxide levels in the Earth's atmosphere and global temperature over the last 160,000 years. Estimates of global temperature at the time air in the bubbles was trapped rely on measuring the relative abundances of hydrogen and its heavier isotope, deuterium, in the ice surrounding the bubbles. When global temperatures are relatively low, water containing deuterium tends to condense and precipitate before reaching the poles; thus, ice deposited at the poles when the global temperature was cooler contained relatively less deuterium than ice deposited at warmer global temperatures. {{U}}Estimates of{{/U}} global temperature based on this information, {{U}}combined with analysis of{{/U}} the carbon dioxide content of air trapped in ice deep beneath the polar surface, {{U}}suggest that during periods of postglacial warming carbon dioxide in the Earth's atmosphere increased by approximately 40 percent.{{/U}} The author states that {{U}}there is evidence to support{{/U}} which of the following assertions? A. Estimates of global temperature that rely on measurements of deuterium in ice deposited at the poles are more reliable than those based on the amount of carbon dioxide contained in air bubbles beneath the polar surface. B. The amount of deuterium in the Earth's atmosphere tends to increase as global temperature decreases. C. Periods of postglacial warming are characterized by the presence of increased levels of carbon dioxide in the Earth's atmosphere. D. Increases in global temperature over the last 160,000 years are largely the result of increases in the ratio of deuterium to hydrogen in the Earth's atmosphere. E. Increases in global temperature over the last 160,000 years have been accompanied by decreases in the amount of deuterium in the ice deposited at the poles.

多选题Some communities in Florida are populated almost exclusively by retired people and contain few, if any, families with small children. Yet these communities are home to thriving businesses specializing in the rental of furniture for infants and small children. Which of the following, if true, best reconciles the seeming discrepancy described above? A. The businesses specializing in the rental of children's furniture buy their furniture from distributors outside of Florida. B. The few children who do reside in these communities all know each other and often make overnight visits to one another's houses. C. Many residents of these communities who move frequently prefer renting their furniture to buying it outright. D. Many residents of these communities must provide for the needs of visiting grandchildren several weeks a year. E. Children's furniture available for rental is of the same quality as that available for sale in the stores.

多选题 Directions: The passage below is followed by questions based on its content. Once you have read the passage, select the answer choice that best answers each question. Answer all questions on the basis of what is stated or implied in the passage. For each of Questions 15-20, select one answer choice unless otherwise instructed. Questions 15-17 are based on the following passage. (The passage was written in the latter half of the 20th century.) The coastlines on the two sides of the Atlantic Ocean present a notable parallelism: the easternmost region of Brazil, inLine Pernambuco, has a convexity that corre- (5) sponds almost perfectly with the concavity of the African Gulf of Guinea, while the con- tours of the African coastline between Rio de Oro and Liberia would, by the same approx- imation, match those of the Caribbean Sea. (10) Similar correspondences are also observed in many other regions of the Earth. This observation began to awaken scientific inter- est about sixty years ago, when Alfred Wegener, a professor at the University of (15) Hamburg, used it as a basis for formulating a revolutionary theory in geological science. According to Wegener, there was origi- nally only one continent or land mass, which he called Pangaea. Inasmuch as continental (20) masses are lighter than the base on which they rest, he reasoned, they must float on the substratum of igneous rock, known as sima, as ice floes float on the sea. Then why, he asked, might continents not be subject to (25) drifting? The rotation of the globe and other forces, he thought, had caused the cracking and, finally, the breaking apart of the origi- nal Pangaea, along an extensive line repre- sented today by the longitudinal submerged (30) mountain range in the center of the Atlantic. While Africa seems to have remained static, the Americas apparently drifted toward the west until they reached their present position after more than 100 million years. Although (35) the phenomenon seems fantastic, accus- tomed as we are to the concept of the rigid- ity and immobility of the continents, on the basis of the distance that separates them it is possible to calculate that the continental (40) drift would have been no greater than two inches per year.
