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: Wyoming's territorial Governor Francis E. Warren visited Rock Springs on September 3, 1885, the day after the riot, to make a personal assessment. After his trip to Rock Springs, Warren traveled to Evanston, where he sent telegrams to U.S. President Grover Cleveland appealing for federal troops. Back in Rock Springs, the riot had calmed, but the situation was still unstable. Two companies of the United States Army's 7th Infantry arrived on September 5, 1885. One company, under the command of a Lieutenant Colonel Anderson, was stationed in Evanston, Wyoming; the other, under a Colonel Chipman, was stationed in Rock Springs. At Camp Murray, Utah Territory, Colonel Alexander McDowell McCook was ordered to augment the garrison sent to Wyoming with six more companies.On September 9, 1885, one week after the massacre, six companies of soldiers arrived in Wyoming. Four of the six companies then escorted the Chinese back to Rock Springs. Once back in Rock Springs, the Chinese laborers found scorched tracts of land where their homes once stood. The mining company had buried only a few dead; others remained lying in the open, mangled, decomposing, and partially eaten by dogs, hogs, or other animals.The situation in Rock Springs was stabilized as early as September 15, when Warren first requested the removal of federal troops, but the mines at Rock Springs remained closed for a time. On September 30, 1885, white miners, mostly Finnish immigrants who were members of the Knights of Labor, walked out of mines in Carbon County, Wyoming, in protest of the company's continued use of Chinese miners. In Rock Springs, the white miners were not back at work in late September, because the company still used Chinese labor. Rock Springs steadily became quieter, and, on October 5, 1885, emergency troops, except for two companies, were removed. However, the temporary posts of Camp Medicine Butte, established in Evanston, and of Camp Pilot Butte, in Rock Springs, remained long after the riot. Camp Pilot Butte closed in 1899 after the onset of the Spanish–American War.The labor strike was unsuccessful, and the miners went back to work within a couple of months. The national Knights of Labor organization refused to support the Carbon strike and the hold out by white miners in Rock Springs following the Rock Springs Riot. The organization avoided supporting the miners along the Union Pacific Railroad, because it did not want to be seen as condoning the violence at Rock Springs. When the Union Pacific Coal Department reopened the mines, it fired 45 white miners connected to the violence.
Output:
What is the full name of the person that contacted the U.S. President?
