OE

When this manager sees a messy desk, she forms a harshly negative opinion of the employee, and as a result ("therefore"), she "demands" that her staff keep their desks clean. Based on the sentence, you can conclude that the manager holds a "strong be-lief" on this subject. Answer choices (B) dogma and (E) tenet both mean an "idea held to be true" and are the correct answers. If someone is dogmatic, that person is very opinionated. Imagine someone refusing to let go of an idea like a dog refusing to let go of a bone! Tenet comes from the Latin word meaning "to hold" and shares its root with tenable ("can be held, defensible") and tenacity ("holding on persistently").
Choices (A) whim and (D)fancy both relate to a "passing thought." While these words can have similar meanings, they do not fit the context of this sentence. Choice (C) hypothesis is a "guess" or a starting point for exploring a problem, not a strongly held belief. Choice (F) polity means a "government" (think "politics") and does not fit the sentence.
