In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Passage: Cleveland's downtown architecture is diverse. Many of the city's government and civic buildings, including City Hall, the Cuyahoga County Courthouse, the Cleveland Public Library, and Public Auditorium, are clustered around an open mall and share a common neoclassical architecture. Built in the early 20th century, they are the result of the 1903 Group Plan. They constitute one of the most complete examples of City Beautiful design in the United States.The Terminal Tower, dedicated in 1930, was the tallest building in North America outside New York City until 1964 and the tallest in the city until 1991. It is a prototypical Beaux-Arts skyscraper. The two newer skyscrapers on Public Square, Key Tower (currently the tallest building in Ohio) and the 200 Public Square, combine elements of Art Deco architecture with postmodern designs. Another of Cleveland's architectural treasures is The Arcade (sometimes called the Old Arcade), a five-story arcade built in 1890 and renovated in 2001 as a Hyatt Regency Hotel.Cleveland's landmark ecclesiastical architecture includes the historic Old Stone Church in downtown Cleveland and the onion domed St. Theodosius Russian Orthodox Cathedral in Tremont, along with myriad ethnically inspired Roman Catholic churches.Running east from Public Square through University Circle is Euclid Avenue, which was known for its prestige and elegance as a residential street. In the late 1880s, writer Bayard Taylor described it as "the most beautiful street in the world". Known as "Millionaire's Row", Euclid Avenue was world-renowned as the home of such major figures as John D. Rockefeller, Mark Hanna, and John Hay.

What street did the writer Bayard Taylor described it as "the most beautiful street in the world"?
