The writer is considering deleting the underlined portion of sentence 1 (reproduced below), adjusting the punctuation as needed. Robots are no longer just the stuff of science fiction: increasingly intelligent and humanlike, they interact with people in new and surprising ways.

Should the writer keep or delete the underlined text?

A. Keep it, because it uses descriptive language to convey the writer’s perspective on advances in robotics and set up the topic of the passage.

B. Keep it, because it establishes an optimistic tone about robot intelligence that the writer will go on to undermine using irony.

C. Delete it, because it makes a claim about advances in technology that is not supported by evidence in the body of the passage.

D. Delete it, because it adds details that do not follow logically from the claim about robots that is made in the first part of the sentence.

E. Delete it, because it undermines the writer’s credibility by giving the impression that the writer is biased in favor of treating robots like humans.
