[单选题]Text 3 Economists across the political spectrum agree that the single biggest threat to future job growth is neither immigration nor trade-it's the artificial intel!igence revotution already underway.Studies by Oxford University,McKinsey and Pricewaterhouse Coopers forecast that up to 50%of current jobs could be replaced by smart machines within the next 20 years.Already,more than 5 million U.S.factory jobs have been lost to automation since 2000.It's become clear:If a job can be automated in the future,it will be.What's less clear is how educational institutions will respond to this sea change in the future of work.Despite belng the envy of the world,American universities have been slow to modernize-too often educating students for 20th century career fields that will be obsolete by the time they graduate.Beyond simply conferring degrees,the foundational purpose of colleges and universities must be to educate-and that means equipping people of all ages,at all stages of their careers,to build successful and fulfilling lives.This means we need to take several important steps to make our students robot-proof.First,we must design and implement a curriculum that empowers humans to do those jobs only humans can do.Call it humanics.This curriculum provides students with three literacies:technical literacy,data literacy and human literacy（such as teamwork,entrepreneurship,ethics and culrural agility）.Then it integrates them,allowing learners to develop a creative mindset and the mental elasticity to invent,discover and produce original ideas in the A.I.age.But a modernized curriculum will not be enough.Students must also gain workplace experience before fully entering the workforce-to deepen their understanding beyond"what"into"why"and"how."For example,an engineering student might exploit her classroom studies in circuitry design during an internship at Waymo,Google's autonomous vehicle project.By integrating firsthand experience with intelligent machines with her academic work,she learns agility and adaptability,and,most important,she learns how to continue learning.Lifelong learning must become a central component of what universities do,not an auxiliary endeavor.This means authentic,sustainable partnerships with industry to design courses that fill competency gaps employers actually need.It means going to where the learners are,providing them with an educational roadmap customized for every walk of life.And it likely means access to a multi-campus network,in which learners circulate among places across the country and around the globe-where they live and work.The economic stakes are high.The well-being of societies has long been tied to vigorous systems of higher education.By rising to the challenge of artificial intelligence,universities with the boldness to change represent humanity's best chance to win the jobs of the future. The Eteneral aim of humanics is to equip students with______
A.job-choosing ability
B.technical literacy
C.social skills
D.creative thinking
