In the past few decades, remarkable findings have been made in ethology, the study of animal social behavior. Earlier scientists had (21) that nonhuman social life was almost totally instinctive or fixed by genetics. Much more careful observation has shown that (22) variation occurs among the social ties of most species, showing that learning is a part of social life. That is, the (23) are not solely fixed by the genes (24) , the learn ing that occurs is often at an early age in a process that is called imprinting. Imprinting is clearly (25) instinctive, but it is not quite like the learning of humans; it is something in between the two. An illustration best (26) the nature of imprinting. Once, biologists thought that ducklings followed the mother duck because of instincts. Now we know that, shortly (27) they hatch, ducklings fix (28) any object about the size of a duck and will henceforth follow it. So ducklings may follow a basketball or a briefcase if these are (29) for the mother duck at the time when imprinting occurs. Thus, social ties can be considera bly (30) , even ones that have a considerable base (31) by genetics.Even among the social insects something like imprinting (32) influence social behav ior. For example, biologists once thought bees communicated with others purely (33) in stinct. But, in examining a "dance" that bees do to indicate the distance and direction of a pollen source, observers found that bees raised in isolation could not communicate effec tively. At a higher level, the genetic base seems to be much more for an all-purpose learn ing rather than the more specific responses of imprinting. Chimpanzees, for instance, gen erally (34) very good mother but Jane Goodali reports that some chimps carry the infant upside down or (35) fail to nurture the young. 33()

U.S. airlines could slash 70,000 more jobs if there were war with Iraq and the U.S. government did not give the industry, more help, the biggest domestic carriers said on Tuesday.The Air Transport Association, which represents major airlines, said in a report on airline finances that its members would take aggressive steps to counter any sharp drop in travel demand and an increase in costs caused by an Iraqi war.Big airlines are seeking government assistance to stem rising fuel costs and ease taxes that are contributing to losses that soared to more than $10 billion in 2002.The industry outlined a "most likely" scenario if war broke out, saying that reduced demand and higher costs due to a conflict lasting 90 days would cost it $4 billion in lost revenue. Without a conflict, losses would still be expected to reach almost $7 billion for the year."The nation’s air carders will continue to do all we can, but we fear that the consequences of this war will be severe," James May, president and chief executive of the air transport group, told a news conference.May restated the industry’s belief that war could prompt more bankruptcies or force some financially fragile carders into liquidation. Recovery would take several years and ticket prices would have to fall further to spur demand.US Airways Group Inc. and UAL Corp’s United Airlines are in Chapter 11 bankruptcy protection, and some industry experts believe that AMR Corp’s American Airlines, the world’s biggest carrier could follow later this year.Airlines expect overall traffic volume during a second Gulf conflict would fall more sharply than it did during the 1991 war, when it declined 8 percent after fighting began.The airlines based their assessment on a slide of more than 20 percent in advance bookings for overseas travel after the U. S. government elevated its domestic terror alert status from yellow to orange in early February.Jet fuel has more than doubled in price from a year ago to, $1.30 a gallon recently. Fuel is the second-largest expense after labor for an airline. An increase of one penny a gallon costs the industry an estimated $180 million annually. The sentence "... AMR, Corp’s American Airlines, the world’s biggest carder, could follow later this year" ( Paragraph 7) can best be restated as ()

A. it would also seek bankruptcy protection
B. it would have to spur its passengers’ demand for tickets
C. it would have to take aggressive steps to avoid bankruptcy
D. it would call for more financial subsidy from the government for its survival
