Teacher: Given a text, write a compressed version of it in a single sentence.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Except for this small vocal minority, we have just not gotten a lot of groundswell against this from members, " says APA president Philip G. Zimbardo of Stanford University.
Solution: "Except for this small vocal minority, we have not gotten a lot of groundswell against this," says APA president Zimbardo.
Reason: Both texts convey the same meaning that they have not gotten much groundswell against this except for small minority.

Now, solve this instance: Readers should be familiar with Robert Claiborne's earlier books, especially Our Marvelous Native Tongue: The Life and Times of the English Language. One might say that subtitling the present book A Book of Lost Metaphors is an example of a loose canon [ sic ] — unless metaphor is taken in its broadest sense—but one is unlikely to find red herrings here: the etymologies of a few hundred words and phrases are given, many not readily findable in standard works of reference.
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
