OFFICIAL EXPLANATION

C


The author of this passage makes the claim that most humans shouldn't worry about losing their jobs to robots or computers in the future because, so far, robots have replaced them only in repetitive jobs. Note that the claim is about the future, while the evidence is about the present; as is common when an argument makes a prediction, the author assumes that the future will be similar to the present. Look for a choice indicating that the capability of computers and robots will change, allowing them to do more kinds of jobs. That's what (C) does. It shows that an artificial intelligence may be able to succeed in artistic endeavors, an ability that would potentially allow technology to compete with humans for more jobs. This is the correct answer.
(A), if anything, strengthens the argument; if robots are more expensive than people, it may be somewhat less likely that companies will use them. (B) is incorrect because who conducts the research is irrelevant; whether created by a business or a university, a robot or computer may be able to take over a human job. (D) can be eliminated because it deals only with the past; so far, people have been able to get new jobs, but there's no guarantee that this will hold true in the future. Finally, (E) may be tempting because it seems to show an advantage of robots over humans: they're more productive than humans in an assembly line. The author, however, already concedes that robots do this job well; her argument is that they won't be able to expand into other fields.
