5. Passage SixteenJustin was always prepared.His motto was “Never throw anything out， you never know when it might come in handy.” His bedroom was so full of flat bicycle tires， bent tennis rackets， deflated basketballs， and games with missing pieces that you could barely get in the door.His parents pleaded him to clean out his room.“What use is a fish tank with a hole in the bottom?” his father asked.But Justin simply smiled and repeated his motto， “Never throw anything out， you never know when it might come in handy.”When Justin was away from home， he always carried his blue backpack.He liked to think of it as a smaller version of his bedroom——a place to store the many objects that he collected.It was so worn and stretched that it hardly resembled a backpack anymore.It was full of the kind of things that seemed unimportant， but when used with a little imagination， might come in handy.Justin had earned a reputation for figuring things out and getting people out of otherwise hopeless situations.Many of his classmates and neighbors sought him out when they needed help with a problem.On the first day of school， his friend Kenny， came looking for Justin.“Do you think you have something in your bag that could help me remember my locker combination?” he asked.“I lost the paper it was written on.I have science class in two minutes and if I’m late on the first day it’ll make me look bad for the rest of the year.” Kenny looked genuinely worried.“Relax，” Justin said， taking his backpack off and opened it.“Remember how you borrowed my notebook in homeroom to write the code down? Well， I know how we can recover what you wrote.”He took the notebook and a soft lead pencil out of his bag.The page that Kenny had written on had left faint indentations (旧凹痕)on another page in the notebook.Justin held the pencil on its side and rubbed it lightly over the indentations.Slowly but surely the numbers of the locker combination appeared in white， set off by the gray pencil rubbings.“That’s amazing!” Kenny said.“I owe you one.” And he dashed off to open his locker.The author’s purpose in writing this story is to ().

5. Passage FifteenBig data can be defined as information that is too big or complex to be contained or processed by any one machine or person.As a student at the University of Sussex， Julian Dailly had two majors——English and philosophy.When he completed his studies， Dailly wondered how he would ever earn a living in a world filled with machines and technology.Now， he is part of the big data industry that includes Google and Facebook.Dailly’s research company， Monar Consulting， started three years ago with five employees.The company’s earnings have increased by 25% each year.It now employs 90 people.“What we do here is we try to discover what’s meaningful for people and link that to their economic behavior，” Dailly said.He noted the importance of working with people with different skills.“We have people from traditional research backgrounds， in addition to some in social sciences， economics， people from tech backgrounds， and sales people，” Dailly said.Companies like Dailly’s employ recent college graduates.The industry profits from the ideas of these young men and women.New forms of data also make it possible for some observers to predict the future.They are more valuable to companies than the traditional forms of data recording or reporting.“We have access to the core information inside people’s heads，” Dailly said， “They tell you what people are going to do as opposed to what they’ve done.That helps people take proper action in advance.This makes it much more useful for strategy.”Julian Dailly dismisses concerns that computers have finally taken control of our daily lives.“Some may worry that humans will be allowed to be replaced by machines.I think it’s a fantasy.”According to Dailly， the idea that humans may be replaced by machines ().
