[单选题]请阅读 Passage1，完成第 21~25小题。Passage 1Two years ago, Rupert Murdoch's daughter, Elisabeth, spoke of the"unsettling dearth of integrity across so many of our institutions". Integrity had collapsed, she argued, because of a collective acceptance that the only"sorting mechanism" in society should be profit and the market. But "it's us, human beings, we the people who create the society we want, not profit".Driving her point home, she continued: "It's increasingly apparent that the absence of purpose, of a moral language within government, media or business could become one of the most dangerous goals for capitalism and freedom." This same absence of moral purpose was wounding companies such as News International, she thought, making it more likely that it would lose its way as it had with widespread illegal telephone hacking.As the hacking trial concludes-finding guilty one ex-editor of the News of theWorld, Andy Coulson, for conspiring to hack phones, and finding his predecessor, Rebekah Brooks, innocent of the same charge-the wider issue of dearth ofintegrity still stands. Journalists are known to have hacked the phones of up to 5,500 people. This is hacking on an industrial scale, as was acknowledged by Glenn Mulcaire, the man hired by the News of the World in 2001 to be the point person for phone hacking. Others await trial. This long story still unfolds.In many respects, the dearth of moral purpose frames not only the fact of such widespread phone hacking but the terms on which the trial took place. One of the astonishing revelations was how little Rebekah Brooks knew of what went on in her newsroom, how little she thought to ask and the fact that she never inquired how the stories arrived. The core of her successful defence was that she knew nothing. In today's world, it has become normal that well-paid executives should not be accountable for what happens in the organisations that they run. Perhaps we should not be so surprised. For a generation, the collective doctrine has been that the sorting mechanism of society should be profit. The words that have mattered are efficiency, flexibility, shareholder value, business-friendly, wealth generation, sales, impact and, in newspapers, circulation. Words degraded to the margin have been justice, fairness, tolerance, proportionality and accountability.The purpose ofediting the News of the World was not to promote reader understanding, to be fair in what was written or to betray any common humanity. It was to nun lives in the quest for circulation and impact. Ms Brooks may or may not have had suspicions about how her journalists got their stories, but she asked no questions, gave no instruction-nor received traceable, recorded nswers.It can be inferred from Paragraph 3 that ____.
