Columnist: Even if the primary purpose of university education is to make students employable, such education should emphasize the liberal arts rather than the more narrow kind of technical training that prepares one for a particular sort of job. This is because the reasoning skills one acquires from a liberal arts education allow one to adapt to new intellectual challenges and thus to perform jobs for which one has received no specialized training. Which one of the following, if true, most strengthens the columnist's argument? ['Having a general understanding of life is more important than possessing practical skills.', 'It is better for people to have good educations than good jobs.', 'Technical training does not help students acquire reasoning skills.', 'Having a series of different jobs is more interesting than having only one job.']
