[单选题]Text 2 In 1946,a 23-year-old Army veteran named John Goodenough headed to the University of Chicago with a dream of studying physics.When he arrived,a professor warned him that he was already too old to succeed in the field.But Dr.Goodenough ignored the professor's advice and today,at 94,has just set the tech industry abuzz with his blazing creativity.He and his team at the University of Texas at Austin filed a patent application on a new kind of battery that,if it works as promised,would be so cheap,lightweight and safe that it would revolutionize electric cars and kill off petroleum-fueled vehicles.We tend to assume that creativity fades with age.But Dr.Goodenough's story suggests that some people actually become more creative as they grow older.A 2016 Information Technology and Innovation Foundation study found that inventors peak in their late 40s and tend to be highly productive in the last half of their careers.Similarly,professors at the Georgia Institute of Technology,who studied data about patent holders,found that,in the United States,the average inventor sends in his or her application to the patent office at age 47,and that the highest-value patents ofien come from the oldest inventors-those over the age of 55.John P.Walsh,one of the professors,joked that the Patent Office should give a"senior discount"since"there's clear evidence that people with seniority are making important contributions to invention."A study ofNobel physics laureates found that,since the 1980s,they bave made their discoveries,on average,at age 50.The peak of creativity for Nobel winners is getting higher every year.For many years,oddsmakers have predicted that Dr.Goodenough would win the Nobel Prize,but so far the call from Stockholm has not come.You might call him the Susan Lucci of chemistry.If he finally does prevail,he could be the oldest person ever to receive the Nobel.The more I talked to Dr.Goodenough,the more I wondered if his brilliance was directly tied to his age.After all,he has been thinking about energy problems longer than just about anyone else on the planet.When I asked him about his late-life success,he said:"Some of us are turtles;we crawl and struggle along,and we haven't maybe figured it out by the time we're 30.But the turtles have to keep on walking."27.What does the phrase"senior discount"in Paragraph 2 most probably convey?
A.Lower standard should be set for senior people.
B.Massive achievements from senior people deserve more awards.
C.What senior people contribute is oflower quality.
D.Senior people need to be charged less.
