Given the task definition, example input & output, solve the new input case.
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.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input case for you: Passage: On May 19, 1927, after waiting for a week for the rain to stop on Long Island, New York, pilot Charles A. "Slim" Lindbergh tries to sleep in a hotel near Roosevelt Field, before his transatlantic flight from New York to Paris. His friend Frank Mahoney guards his hotel room door from reporters. Unable to sleep, Lindbergh reminisces about his time as an airmail pilot.
Flying to Chicago in winter, "Slim" lands his old de Havilland biplane at a small airfield to refuel. Despite bad weather, he takes off, unaware that heavy snow has closed the Chicago landing field. Lindbergh bails out in a storm after running out of fuel. Recovering mail from his crashed DH-4, he continues to Chicago by train. A salesman tells him two airmen just died competing for the Orteig Prize for the first nonstop flight from New York City to Paris. Lindbergh calls Columbia Aircraft Corporation in New York from a small diner at the Lambert-St. Louis Flying Field. Quoted a price of $15,000 ($220,000 today) for a Bellanca high-wing monoplane, "Slim" lobbies St. Louis financiers with a plan to fly the Atlantic in 40 hours in a stripped-down, single-engine aircraft. The backers are excited by Lindbergh's vision and dub the venture Spirit of St. Louis.
When the Bellanca deal falls apart because Columbia insists on selecting the pilot, Lindbergh approaches Ryan Aeronautical Company, a small manufacturer in San Diego, California. Frank Mahoney, the company's owner and president, promises to build a suitable monoplane in just 90 days. With Ryan's chief engineer Donald Hall, a design takes shape. To decrease weight, "Slim" refuses to install a radio or other heavy equipment, even a parachute, and plans to navigate by "dead reckoning". With no autopilot function Lindbergh cannot sleep during the flight. Workers at the factory agree to work around-the-clock to complete the monoplane in less than 90 days.
Output:
What is the full name of the person whose friend guards their hotel room from reporters?
