Priests,teachers and parents have for generations advised their wards io think twice before speaking,to count to ten when angry and to get a good night's sleep before making big decisions.Social networks care little for seconcl thoughts.Services such as Facebook and Twitter are built to maximise"virality",making it irresistible to share,like and retweet things.They are getting better at it:fully half of the 40 most-retweeted tweets clate from January last year.Starting this month,however,users of WhatsApp,a messaging service owned by Facebook,will find it harder to spread content.They will no longer be able to forward messages to more than 20 0thers in one go,down from more than 100.The goal is not to prevent people from sharing information-only to get users to think about what they are passing on.It Js an idea other platforms should consider copying.Skeptics point out that WhatsApp can afford to hinder the spread of information on its platform because it does not rely on the sale of adverrisements to make money.Slowing down sharing would be more damaging to social networks such as Facebook and Twitter,which make money by keeping users on their sites and showing them ads.Their shareholders would surely refuse anything that lessens engagement.Sure enough,Facebook's shares fell by 23%in after-hours trading,partly because Mark Zuckerberg,its boss,said that its priority would be to get users to interact more with each other,not to promote viral content.Yet the short-term pain caused by a decline in virality may be in the long-term interests of the social networks.Fake news and concerns about cligital addiction,among other things,have already damaged the reputations of tech platforms.Moves to slow sharing could lielp see off harsh action by regulators and lawmakers.They could also improve its service.Instagram,a photo-sharing social network also owned by Facebook,shows that you can be successful without resorting to virality.It offers no sharing options and does not allow links but boasts more than a billion monthly users.It has remained relatively free of misinformation.Facebook does not break out Instagram's revenues,but it is thought to make money.The need to constrain virality is becoming ever more urgent.About half the world uses the internet today.The next 3.8bn users to go online will be poorer and less familiar with media.The examples of deceptions,misinformation and violence in India suggest that the capacity to manipulate people online is even greater when they first gain access to cligital communications.Small changes can have big effects:social networks have become expert at making their services compulsive by adjusting shades of blue and the size of buttons.They have the knowledge and the tools to maximise the sharing of information.That gives them the power to limit its virality,too.
It can be inferred from Paragraphs 4 and 5 that controlling virality couldA.eliminate concerns about digital addiction.
B.keep a social network free of misinformation
C.contribute to the success of a social network.
D.exempt a social network from harsh regulation

Rats and other animals need to be highly at tuned to social signals from others so that can identify friends to cooperate with and enemies to avoid.To find out if this extends to non-living beings,Loleh Quinn at the University of California,San Diego,and her colleagues tested whether rats can detect social signals form robotic rats.They housed eight adult rats with two types of robotic rat-one social and one asocial一for 5 our days.The robots rats were quite minimalist,resembling a chunkier version of a computer mouse with wheels-to move around and colorful markings.During the experiment,the social robot rat followed the living rats around,played with the same toys,and opened caged doors to let trapped rats escape.Meanwhile,the asocial robot simply moved forwards and backwards and side to side Next,the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.Across 18 trials each,the living rats were 52 percent more likely on average to set the social robot free than the asocial one.This suggests that the rats perceived the social robot as a genuine social being.They may have bonded more with the social robot because it displayed behaviours like communal exploring and playing.This could lead to the rats better remembering having freed it earlier,and wanting the robot to return the favour when they get trapped,says Quinn.The readiness of the rats to befriend the social robot was surprising given its minimal design.The robot was the same size as a regular rat but resembled a simple plastic box on wheels.“We'd assumed we'd have to give it a moving head and tail,facial features,and put a scene on it to make it smell like a real rat,but that wasn’t necessary,”says Janet Wiles at the University of Queensland in Australia,who helped with the research.The finding shows how sensitive rats are to social cues,even when they come from basic robots.Similarly,children tend to treat robots as if they are fellow beings,even when they display only simple social signals.“We humans seem to be fascinated by robots,and it turns out other animals are too,”says Wiles.
It can be learned from the text that rats________A.appear to be adaptable to new surroundings
B.are more socially active than other animals
C.behave differently from children in socializing
D.are more sensitive to social cues than expected
