Science has long had an uneasy relationship with other aspects of culture. Think of Gallileo’s 17th-century trial for his rebelling belief before the Catholic Church or poet William Blake’’s harsh remarks against the mechanistic worldview of Isaac Newton. The schism between science and the humanities has, if anything, deepened in this century. Until recently, the scientific community was so powerful that it could afford to ignore its critics but no longer. As funding for science has declined, scientists have attacked "antiscience" in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl Sagan of Cornell University. Defenders of science have also voiced their concerns at meetings such as" The Flight from Science and Reason," held in New York City in 1995,and "Science in the Age of (Mis) information, "which assembled last June near Buffalo. Antiscience clearly means different things to different people. Gross and Levitt find fault primarily with sociologists, philosophers and other academics who have questioned science’’s objectivity. Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview. A survey of news stories in 1996 reveals that the antiscience tag has been attached to many other groups as well, from authorities who advocated the elimination of the last remaining stocks of smallpox virus to Republicans who advocated decreased funding for basic research. Few would dispute that the term applies to the Unabomber, whose manifesto published in 1995, scorns science and longs for return to a pretechnological Utopia. But surely that does not mean environmentalists concerned about uncontrolled industrial growth are antiscience, as an essay in US News & World Report last May seemed to suggest. The environmentalists, inevitably, respond to such critics. The true enemies of science, argues Paul Ehrtich of Stanford University, a pioneer of environmental studies, are those who question the evidence supporting global warming, the depletion of the ozone layer and other consequences of industrial growth. Indeed, some observers fear that the antiscience epithet is in danger of becoming meaningless. "The term ’’ antiscience’’ can lump together too many, quite different things, "notes Harvard University philosopher Gerald Holton in his 1993 work Science and Anti-Science. "They have in common only one thing that they tend to annoy or threaten those who regard themselves as more enlightened."

Water is the oldest form of transport. The original sailing vessels were replaced by steamboats in the early 1800s and by diesel power in the 1920s. A distinction is generally made between deepwater and navigable inland water transport. Domestic commerce centers on tile Great Lakes, canals, and navigable rivers. In 1975 water transport accounted for 22.6 percent of total intercity tonnage. Its relative share of intercity tonnage was 31.3 percent in 1947 and 31.7 percent in 1958. Tonnage declined to 27.9 percent in 1965 but increased by 1970 to 28.4 percent. This short-term increase did not stabilize. Market share dropped by 5.8 percent by 1975. Forecasted market share by 1985 is 18.4 percent of total intercity tonnage. The water transport share of revenue has been less than 2 percent of intercity freight revenue since 1955. The exact miles of improved waterways in operation depend in part on whether coastwise and intercostal shipping are included. Approximately 26,000 miles of improved inland waterways were operated in 1975. Fewer miles of improved inland waterways exist than of any other transportation mode. The main advantage of water transport is the capacity to move extremely large shipments. Deepwater vessels are restricted in operation, but diesel-towed barges have a fair degree of flexibility. In comparison to rail and highway, water transport ranks in the middle with respect to fixed cost. The fixed cost of operation is greater than that of motor carriers but less than that of railroads. The main disadvantage of water is the limited degree of flexibility and the low speeds of transport. Unless the source and destination of the movement are adjacent to a waterway, supplemental haul by rail or truck is required. The capability of water to transport large tonnage at low variable cost places this mode of transport in demand when low freight rates are desired and speed of transit is a secondary consideration. Freight transported by inland water leans heavily to mining and basic bulk commodities, such as chemicals, cement, and selected agricultural products. In addition to the restrictions of navigable waterways, terminal facilities for bulk arid dry cargo storage and load-unload devices limit the flexibility of water transport. Labor restrictions on loading and unloading at dock level create operational problems and tend to reduce the potential range of available traffic. Finally, a highly competitive situation has developed between railroads and inland water carriers in areas where parallel routings exist. Inland and Great Lakes water transport will continue to be a viable alternative for future logistical system design. The full potential of the St. Lawrence Seaway has not yet been realized with respect to domestic freight. The slow passage of inland river transport can provide a form of warehousing in transit if fully integrated into overall system design. Improvements in ice-breaking equipment appear on the verge of eliminating the seasonal limitations of water transport. Which of the following statements is true according to the article
A. Steamboats are the original sailing vessels.
B. Steam power followed diesel power.
C. Deepwater and navigable inland water transport are equivalents.
D. There is domestic commerce in the Atlantic Ocean.
