Recent studies indicate that people who spend significant time browsing the World Wide Web do so at the expense of time spent in face-to-face interaction with other people. This has led some to fear that social isolation will greatly increase because of the popularity of browsing the Web. But, since browsing the Web is just one of many popular solitary activities, and any time spent on a solitary activity is time spent not interacting face-to-face with other people, such fears are unwarranted. Which one of the following most accurately describes the role played in the argument by the view that social isolation will greatly increase because of the popularity of browsing the Web? ['It is a premise that, together with another premise, is meant to support the conclusion of the argument.', 'It is the overall conclusion of the argument.', 'It is the claim that the argument attempts to undermine.', 'It is presented as evidence that independently supports the conclusion of the argument.']
