The Phantom Tollbooth Practice Test

In this story, places are built around ideas, and Dictionopolis is the city dedicated to language. It’s described as a bustling market where words and letters are treated as tangible goods you can trade—nouns, verbs, adjectives, and individual letters alike are bought and sold, with the ruler of the city overseeing this world of words. That focus on language—trading and manipulating words and letters—is what makes it the correct location for this question. The other places have different emphases: Digitopolis centers on numbers; the Valley of Sound deals with sounds; the Isle of Conclusions is about drawing conclusions.
