OE


B, E The straight-ahead road sign "upon" reveals how the class president reacted to the "incendiary" article. The word "incendiary" literally means "designed to cause fires." When used metaphorically, however, it means "tending to cause conflict." After reading the conflict-causing article, the class president "felt compelled" to respond and "voice his objections." Predict something that follows from the adjective "incendiary": what would someone write to "voice his objections" in response to such an article? It could be something neutral like "response" or something more charged, like "protest" or "complaint." There is an additional clue in the word "harangue," which means "rant," so "protest" is a good prediction. (B) and (E) match nicely and are correct: they both mean "a verbal attack."
(A) missive means "letter." A person could certainly write a letter to an editor, but this has no match among the answer choices, nor is it as charged as the word "harangue" would lead you to expect. (C) tome ("a book, especially a long one") is not supported by the clues in the sentence. It's possible the response was long, but the sentence does not indicate that. Additionally, tome has no match among the other choices. A quandary (D) is a "dilemma," and while a protest or complaint might create a quandary, they are not the same thing. Finally, (F) hypothesis, "an explanation proposed for a given phenomenon," does not match the context of the sentence, which gives no hint that the class president seeks to explain anything.
