Text 1 When I started my careef I was astonished by how superhuman some Fortune 500 executives were.It seemed they were magicians.Every decision they made based on deep market knowledge and up-to-date information.How did they do it?Thcy have marketing teams that can pull research together in hours.They have chiefs of staff who give them carefully crafied agendas for every day.These teams give Fortune 500 executives what appears to bc super-human knowledge.Foriunately for those of us who don't have Fortune 500 budgets at our disposal,it's getting easier and casier to build your own secret support staff.Within five years,most executives at any size company-and,indeed,most knowledge workers-will have tools that do much of the work of a CEO's private group.That is,"Cyborg systems,"or what I called"agents".It will make this possible,using a blend of learning algorithms and distributed labor to perform an ever-widening range of tasks at low cost.With help from these agents,we'II be able to look as smari as those CEOs do today.I got one taste of this when I started using Wonder.Wonder is like having a personal researcher,deploying a small army of experts,including trained librarians,to do small,defined research projects for me.I ask Wonder for help.For$30 to$60,Wonder saves me hours every week.More and more products and services will fuse machine intelligence with crowd work to help users get things done.To be clear,CEO support teams aren't going away.Top executives will continue to see benefits from dedicated,trusted support staff who can handle difficult,urgent,delicate work.But machine intelligence systems can take on elements of what these people do at a much lower cost,democratizing many of these capabilities.Granted,there is going to be a lot of garbage before we realize the full promise of these virtual support armies.Many ofthem fail to live up to even basic promises,like this weather bot that has trouble telling you about the weather.But if you can filter through the many new offerings to fmd valuable tools,your work will improve and you may even start to look like those CEOs with the seemingly.
Top executives will continue to benefit from support teams because________.

A.theyworkatamuchlowercost
B.theycanfulfilltheirpromise
C.theyaremoreintelligent

Text 1 The love of money ,St Paul memorably wrote to his protege Timothy, is the root of all evil. All may be putting it a bit strongly,but dozens of psychological studies have indeed shown that people primed to think about money before an experiment are more likely to lie,cheat and steal during the course of that experiment.Another well-known aphorism,ascribed to Benjamin Franklin,is time is money .If true,that suggests a syllogism:that the love of time is a root of evil,too.But a paperjust published in Psychological Science by Francesca Gino of Harvard and Cassie Mogilner of the University of Pennsylvania suggests precisely the opposite.Dr Gino and Dr Mogilner asked a group of volunteers to do a scries of what appeared to be aptitude tests.As is ofien the case in such experiments,though,what the voiunteers were told.and what the truth was,were rather different things.In the first test they were asked to make,within three minutes,as many coherent sentences as they could out of a set ofwords they had been presented with.What they were not told was that each of them had been assigned to one of three groups.Some volunteers'word sets were seeded with ones associated with money,such as dollars , financing and spend .Some were seeded with words associated with time（eg, clock , 'hours , moment ）.And some were seeded with neither.Thus unknowingly primed,the volunteers were ready for the second test.This was mathematical.They were given a sheet of paper with 20 matrices which each contained 12 numbers.two of which added up to ten（for example,3.81 and 6.19）.They had to write down,on a separate answer sheet,how many of these pairs they could manage to find in five minutes.They were also given a packet ofmoney and told they could reward themselves with a dollar for each pair they discovered.This led Dr Gino and Dr Mogilner to suspect that self-reflection played a part in controlling uncthical behaviour during the test.They therefore conducted a third test in which,for half the volunteers,there was a mirror in the cubicle they were sitting in when doing the experiment.Volunteers primed to think about money cheated 39%of the time when a mirror was present but 67%when it was not.Those primed to think about time cheated 32%of the time in the presence of the mirror and 36%in its absence-results that are statistically indistinguishable.Finally,a fourth experiment asked primed volunteers to fill in a questionnaire before tackling the matrix.In among filler questions intended to disguise what was happening this asked them to rate how they felt about self-reflective statements like, Right now,1 am thinking about who I am as a person. As in the previous tests,those primed with money words cheated more ofien than those primed with neutral words and far more ofien than those primed with time words.But whether someone cheated was also related to how strongly he felt about the self-reflective statements presented to him in the questionnaire.It seems,then,that thinking about time has the opposite effect on people from thinking about money.It makes them more honest than normal,rather than less so.Moreover,the more reflective they are,the more honest they become.There must be an aphorism in that.The author's attitude towards the conclusion of the experiment is——.

A.disapproval
B.suspicious
C.supportive
D.certain
