单选题{{B}}Passage 4{{/B}} In the summer of 999, Leif Erikson voyaged to Norway and spent the following winter with King Olaf Tryggvason. Substantially the same account is given by both the Saga of Eric the Red and the Flat Island Book. The latter says nothing about Leif's return voyage to Greenland, but according to the former it was during this return voyage that Leif discovered America. The Flat Island Book, however, tells of another and earlier landfall by Biarni, the son of a prominent man named Heriulf, and makes that the inspiration for the voyage to the new land by Leif. In brief, like Leif, Biarni and his companion sight three countries in succession before reaching Greenland, and to come upon each new land takes 1 "doegr" more than the last until Biarni comes to land directly in front of his father's house in the last- mentioned country. This narrative has been rejected by most later writers, and they may be justified. Possibly, Biarni was a companion of Leif when he voyaged from Norway to Greenland via America, or it may he that the entire tale is But a garbled account of that voyage and Biarni another name for Leif. It should be noted, however, that the stories of Leif's visit to King Olaf and Biarni's to that king's predecessor are in the same narrative in the Flat Island Book, so there is less likelihood of duplication than if they were from different sources. Also, Biarni landed on none of the lands he passed, but Leif apparently landed on one, for he brought back specimens of wheat, vines, and timber. Nor is there any good reason to believe that the first land visited by Biarni was Wineland. The first land was "level and covered with woods", and "there were small hillocks upon it'. Of forests, later writers do not emphasize them particularly in connection with Wineland, though they are often noted incidentally. And of hills, the Saga says of Wineland only that "wherever there was hilly ground, there were vines". Additionally, if the two narratives were taken from the same source we should expect a closer resemblance of Helluland. The Saga says of it: "They found there hellus (large flat stones)." According to the Biarni narrative, however, "this land was high and mountainous." The intervals of 1, 2, 3, and 4 "doegr" in both narratives are suggestive, but mythic formulas of this kind may be introduced into narratives without altogether destroying their historicity. It is also held against the Biarni narrative that its hero is made to come upon the coast of Greenland exactly in front of his father's home. But it should be recalled that Heriufsness lay below two high mountains which served as landmarks for navigators. I would give up Biarni more readily were it not that the story of Leif's voyage contained in the supposedly more reliable Saga is almost as amazing. But Leif's voyage across the entire width of the North Atlantic is said to be "probable" because it is incorporated into the narrative of a preferred authority, while Biarni's is "improbable" or even "impossible" because the document containing it has been condemned.

单选题Science, in practice, depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets. What kept them in place? Why didn"t they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets. How many men would have considered the possibility of an apple falling up into the tree? Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research. If you don"t have unpredictable things, you don"t have research. Scientists tend to forget this when writing their cut and dried reports for the technical journals, but history is filled with examples of it. In talking to some scientists, particularly younger ones, you might gather the impression that they find the "scientific method"—a substitute for imaginative thought. I"ve attended research conferences where a scientist has been asked what he thinks about the advisability of continuing a certain experiment. The scientist has frowned, looked at the graphs, and said "the data are still inconclusive." "We know that," the men from the budget office have said, "but what do you think? Is it worthwhile going on? What do you think we might expect?" The scientist has been shocked at having even been asked to speculate. What this amounts to, of course, is that the scientist has become the victim of his own writings. He has put forward unquestioned claims so consistently that he not only believes them himself, but has convinced industrial and business management that they are true. If experiments are planned and carried out according to plan as faithfully as the reports in the science journals indicate, then it is perfectly logical for management to expect research to produce results measurable in dollars and cents. It is entirely reasonable for auditors to believe that scientists who know exactly where they are going and how they will get there should not be distracted by the necessity of keeping one eye on the cash register while the other eye is on the microscope. Nor, if regularity and conformity to a standard pattern are as desirable to the scientist as the writing of his papers would appear to reflect, is management to be blamed for discriminating against the "odd balls" among researchers in favor of more conventional thinkers who "work well with the team".
