问题 Text 3 In his book The Tipping Point,Malcolm Gladwell argues that social epidemics are driven in large part by the acting of a tiny minority of special individuals,often called influentials,who are unusually informed,persuasive,or well-connected.The idea is intuitively compelling,but it doesn't explain how ideas actually spread.The supposed importance of influentials derives from a plausible sounding but largely untested theory called the"two step flow of communication":Information flows from the media to the influentials and from them to everyone else.Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influentials,those selected people will do most of the work for them.The theory also seems to explain the sudden and unexpected popularity of certain looks,brands,or neighborhoods.In many such cases,a cursory search for causes finds that some small group of people was wearing,promoting,or developing whatever it is before anyone else paid attention.Anecdotal evidence of this kind fits nicely with the idea that only certain special people can drive trends In their recent work,however,some researchers have come up with the finding that influentials have far less impact on social epidemics than is generally supposed.In fact,they don't seem to be required of all.The researchers'argument stems from a simple observing about social influence,with the exception of a few celebrities like Oprah Winfrey—whose outsize presence is primarily a function of media,not interpersonal,influence—even the most influential members of a population simply don't interact with that many others.Yet it is precisely these non-celebrity influentials who,according to the two-step-flow theory,are supposed to drive social epidemics by influencing their friends and colleagues directly.For a social epidemic to occur,however,each person so affected,must then influence his or her own acquaintances,who must in turn influence theirs,and so on;and just how many others pay attention to each of these people has little to do with the initial influential.If people in the network just two degrees removed from the initial influential prove resistant,for example,the cascade of change won't propagate very far or affect many people.Building on the basic truth about interpersonal influence,the researchers studied the dynamics of populations manipulating a number of variables relating of populations,manipulating a number of variables relating to people's ability to influence others and their tendency to be influenced.Our work shows that the principal requirement for what we call"global cascades"–the widespread propagation of influence through networks–is the presence not of a few influentials but,rather,of a critical mass of easily influenced people.33.What the researchers have observed recently shows thatA.the power of influence goes with social interactionsB.interpersonal links can be enhanced through the mediaC.influentials have more channels to reach the publicD.most celebrities enjoy wide media attention

选项 A.the power of influence goes with social interactions
B.interpersonal links can be enhanced through the media
C.influentials have more channels to reach the public
D.most celebrities enjoy wide media attention

答案 A

解析根据题干，线索大致定位到第三四段，但是第三段并没有清晰的找到题解，而接下来的第四段，由该段最后一句清晰推理出了影响范围与社会互动的密切关系，影响能否传播下去，关键在于社会大众是否愿意互动，积极参与其中。A选项充分的表明了这一点。B、C、D三个选项的说法按照常识判断都可能正确，但是不是文章要阐述的内容，所以排除。【补充】本文并不是简单的考查研究人员观察到的事实，而是考查从事实中推出的结论，因此正确答案不容易直接选出，用排除法做题。
