Answer:
B. The writer demonstrates that the researchers have never actually tested their robot.
Explanation:
It would be B because A says that the writer is a journalist who might lose his job for making false claims. We can tell right away that this is an outlier and is incorrect. C is incorrect because the paragraoh says nothing about the writer or anyone being the president of a university. D is incorrect because no where in the story, does the writer point out any errors in the researchers' method. I'm so sorry if I'm incorrect. I'm 99.999999% sure this is correct. I had this assignment yesterday.
