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.
Example solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: 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.

Problem: Passage: The rebellion changed the dynamic between settlers and local tribes.  Although the Cherokee repudiated the rebellion, their initial support caused many settlers to distrust the tribe. The rebellion and subsequent Mexican army response also changed the settlers' relationships with other tribes. In preceding years, the Tawakoni and Waco tribes, allied with various Comanche bands, had regularly raided Texas settlements.  Fearing that the tribes, like the Cherokee, could ally with other groups against Mexican control, Bustamante began preparations to attack and weaken all hostile tribes in East Texas. On learning of the imminent invasion, in April 1827 the Towakoni and Waco sued for peace. In June, the two tribes signed a peace treaty with Mexico, promising to halt all raids against Mexican settlers. The Towakoni then assisted their allies, the Penateka Comanche, in reaching a treaty with Mexico. When Bustamante's troops left Texas later that year, the Towakoni and Waco resumed their raiding. The Comanche tribe upheld their treaty for many years and often assisted Mexican soldiers in recovering livestock stolen by the other tribes.The failed rebellion also affected Mexican relations with the United States. Even before the revolt, many Mexican officials had worried that the United States was plotting to gain control of Texas. Once the rebellion came to light, officials suspected that Edwards had been an agent of the United States. To help protect the region, a new, larger, garrison was established in Nacogdoches, to be commanded by Colonel Jose de las Piedras. As a direct result of Edwards's actions, the Mexican government authorized an extensive expedition, conducted by General Manuel de Mier y Terán, to inspect the Texas settlements and to recommend a future course of action. Mier y Teran's reports led to the Law of April 6, 1830, which severely restricted immigration into Texas. Within Texas, the laws were widely denounced by both recent immigrants and native-born Mexicans and led to further armed conflict between Mexican soldiers and Texas residents.Some historians regard the Fredonian Rebellion as the beginning of the Texas Revolution.   Historian W.B. Bates remarked that the revolt was "premature, but it sparked the powder for later success." The people of Nacogdoches played instrumental roles in other rebellions in Texas over the next few years; in 1832, they expelled Piedras and his troops from Nacogdoches, and many Nacogdoches residents participated in the Texas Revolution.
Solution: Who expelled Piedras and his troops from Nacogdoches?
