1.Excavation of the ancient city of Kourion on the island of Cyprus revealed a pattern of debris and collapsed buildings typical of towns devastated by earth-quakes. Archaeologists have hypothesized that the destruction was due to a major earthquake known to have occurred near the island in A.D.365. Which of the following， if true， most strongly supports the archaeologists hypothesis？

（A） Bronze ceremonial drinking vessels that are often found in graves dating from years preceding and following A.D.365 were also found in several graves near Kourion.

（B） No coins minted after A.D.365 were found in Kourion， but coins minted before that year were found in abundance.

（C） Most modern histories of Cyprus mention that an earthquake occurred near the island in A.D.365.

（D） Several small statues carved in styles current in Cyprus in the century between A.D.300 and 400 were found in Kourion.

（E） Stone inscriptions in a form of the Greek alphabet that was definitely used in Cyprus after A.D.365 were found in Kourion.

2.In Swartkans territory， archaeologists discovered charred bone fragments dating back 1 million years. Analysis of the fragments， which came from a variety of animals， showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white stink-wood， the most common tree around Swartkans.

Which of the following， if true， would， together with the information above， provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids？

（A） The white stinkwood tree is used for building material by the present day inhabitants of Swartkans.

（B） Forest fires can heat wood to a range of temperatures that occur in campfires.

（C） The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals.

（D） Apart from the Swartkans discovery， there is reliable evidence that early hominids used fire as many as 500 thousand years ago.

（E） The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.

3.Black Americans are， on the whole， about twice as likely as White Americans to develop high blood pressure. This likelihood also holds for westernized Black Africans when compared to White Africans. Researchers have hypothesized that this predisposition in westernized Blacks may reflect an interaction between western high-salt diets and genes that adapted to an environmental scarcity of salt.

Which of the following statements about present-day， westernized Black Africans， if true， would most tend to confirm the researchers hypothesis？

（A） The blood pressures of those descended from peoples situated throughout their history in Senegal and Gambia， where salt was always available， are low.

（B） The unusually high salt consumption in certain areas of Africa represents a serious health problem.

（C） Because of their blood pressure levels， most White Africans have markedly decreased their salt consumption.

（D） Blood pressures are low among the Yoruba， who， throughout their history， have been situated far inland from sources of sea salt and far south of Saharan salt mines.

（E） No significant differences in salt metabolism have been found between those people who have had salt available throughout their history and those who have not.

4.Two decades after the Emerald River Dam was built， none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees， scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.

Which of the following statements， if true， would most strengthen the scientists hypothesis？

（A） The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.

（B） Before the dam was built， the Emerald River annually overflowed its banks， creating backwaters that were critical breeding areas for the native species of fish.

（C） The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees， whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.

（D）Nonnative species of fish， introduced into the Emerald River after the dam was built， have begun competing with the declining native fish species for food and space.

（E） Five of the fish species native to the Emerald River are not native to any other river in North America.

5. An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Car Company cites as evidence the fact that over half of all automobiles built by the company since 1970 are still on the road today， compared to no more than a third for any other manufacturer.

Which of the following， if true， most strongly supports the advertisements argument？

（A） After taking inflation into account， a new Deluxe automobile costs only slightly more than a new model did in 1970.

（B） The number of automobiles built by Deluxe each year has not increased sharply since 1970.

（C） Owners of Deluxe automobiles typically keep their cars well maintained.

（D） Since 1970， Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.

（E） Deluxe automobiles have been selling at relatively stable prices in recent years.
