Ask AZBlog. From a Stanford student who’s worked with me, a query on behalf of her mother and her brother, who was confronted by this item on a PSAT exam:
31. Viewing it (A) from Earth, the planet Mars seems to be rushing (B) eastward through the constellations, as if (C) in a futile (D) effort to escape from the Sun. No error (E)
In this sort of question, the student’s task is to identify one of the four underlined expressions (labeled A through D) as an error in grammar, or to answer E if there’s no error in the sentence. There are not many such questions, so that getting just one answer “wrong” affects the student’s score significantly.
In this case, my friend’s brother answered E (as I would have), and that was marked wrong. What’s going on here?
