假日连锁店的住客们每年从它们的2638家分店中卷走50万条毛巾,酒店想知道这些毛巾后来的遭遇如何。不过,假日酒店并没有对顺手牵羊者兴师问罪的意思,只想让他们为一次全国性促销活动添砖加瓦。酒店宣布对这些客人实施特赦,条件是要他们讲出这些年中被拿走的那些毛巾都派上了什么用场。1.每收到一个故事,假日酒店就向一个慈善机构捐款1美元。这个机构是假日酒店在1986年成立的,目的就是帮助患有致命疾病的儿童。假日酒店品牌管理高级副总裁马克说:“这是件轻松愉快的事情,只不过是让人们站出来讲述自己的故事。如果他们心里因衣柜存有一条假日酒店毛巾而残留着些许愧疚感的话,这一来也就烟消云散了。”2.这家连锁店要求客人们将自己的故事放到酒店的网站上,然后评选出25个最佳故事,故事的主人将获得一条限量珍藏的假日酒店毛巾。网站已经收到了数百个故事。一名男子说他在墨西哥蒙特雷的假日酒店拿了一条毛巾作为蜜月夜晚的纪念,后来,伊人已去,毛巾犹存。3.其实,失去一条毛巾只会给酒店造成3美元的损失,但酒店并不介意客人拿走毛巾,而大多数客人也认为房价中已经包含了毛巾的费用。

The potential of computers for increasing the control of organizations or society over their members and for invading the privacy of those members has caused considerable concern.The privacy issue has been raised most insistently with respect to the creation and maintenance of data files that assemble information about persons from a multitude of sources. Files of this kind would be highly valuable for many kinds of economic and social research, but they are bought at too high a price if they endanger human freedom or seriously enhance the opportunities of black-mailers. While such dangers should not be ignored, it should be noted that the lack of comprehensive data files has never before been the limiting barrier to the suppression of human freedom.Making the computer the villain in the invasion of privacy or encroachment on civil liberties simply diverts attention from the real dangers. Computer data banks can and must be given the highest degree of protection from abuse. But we must be careful, also, that we do not employ such crude methods or protection as to deprive our society of important data it needs to understand its own social processes and to analyse its problems.Perhaps the most important question of all about the computer is what it has done and will do to man’s view of himself and his place in the universe. The most heated attacks on the computer are not focused on its possible economic effects, its presumed destruction of job satisfaction, or its threat to privacy and liberty, but upon the claim that it causes people to be viewed, and to view themselves, as "machines".What the computer and the progress in artificial intelligence challenge is an ethic that rests on man’s apartness from the rest of nature. An alternative ethic, of course, views man as a part of nature, governed by natural law, subject to the forces of gravity and the demands of his body. The debate about artificial intelligence and the simulation of man’s thinking is, in considerable part, a confrontation of these two views of man’s place in the universe. If you had to split this passage into two sections, where would be the best place to make the division().

A. after the first paragraph
B. after the second paragraph
C. after the third paragraph
D. after the fourth paragraph
