问题 Text 2 An old saying has it that half of all advertising budgets are wasted-the trouble is,no one knows which half.In the internet age,at least in theory,this fraction can be much reduced.By watching what people search for,click on and say online,companies can aim“behavioural”ads at those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information:Should advertisers assume that people are happy to be tracked and sent behavioural ads?Or should they have explicit permission?In December 2010 America's Federal Trade Cornmission（FTC）proposed adding a"do not track"（DNT）option to internet browsers,so that users could tell adwertisers that they did not want to be followed.Microsoft's Internet Explorer and Apple's Safari both offer DNT;Google's Chrome is due to do so this year.In February the FTC and Digltal Adwertising Alliance（DAA）agreed that the industry would get cracking on responging to DNT requests.On May 31st Microsoft Set off the row:It said that Internet Explorer 10,the version due to appear windows 8,would have DNT as a default.It is not yet clear how advertisers will respond.Geting a DNT signal does not oblige anyone to stop tracking,although some companies have promised to do so.Unable to tell whether someone really objects to behavioural ads or whether they are sticking with Microsoft’s default,some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone.Atter all,it has an ad business too,which it says will comply with DNT requests,though it is still working out how.If it is trying to upset Google,which relies almost wholly on default will become the norm.DNT does not seem an obviously huge selling point for windows 8-though the firm has compared some of its other products favourably with Google's on that count before.Brendon Lynch,Microsoft's chief privacy officer,bloggde:"we believe consumers should have more control."Could it really be that simple?26.It is suggested in paragraph 1 that“behavioural”ads help advertisers to:A.ease competition among themselvesB.lower their operational costsC.avoid complaints from consumersD.provide better online services
选项 A.ease competition among themselves
B.lower their operational costs
C.avoid complaints from consumers
D.provide better online services
答案 B
解析 事实细节根据题干，首先定位到首段中的句子companies can aim“behavioral”ads at those most likely to buy.这段的大意是：在互联网时代，通过观察用户在线的搜索、点击和评论行为，公司能够向那些最可能买账的用户投放“behavioral”广告，使得广告更有针对性，从而降低预算成本，也就是“this fraction can be much reduced”，与答案B“lower their operational costs”是同意替
