Definition: 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.
Input: Passage: Prior to settlement by Europeans, the area where the city developed, at the forks of the Red River  and Red Lake River, for thousands of years had been an important meeting and trading point for Native Americans. Early French explorers, fur trappers, and traders called the area Les Grandes Fourches, meaning "The Grand Forks". By the 1740s, French fur trappers relied on Les Grandes Fourches as an important trading post. This was French colonial territory.The United States acquired the territory from British Rupert's Land with the Treaty of 1818, but indigenous tribes dominated the area until the late 19th century. After years of warfare, the United States made treaties to extinguish the land claims of the Ojibwe and other Native American peoples. When a U.S. post office was established on the site on June 15, 1870, the name was changed to the English "Grand Forks". Alexander Griggs, a steamboat captain, is regarded as "The Father of Grand Forks". Griggs' steamboat froze in the Red River on a voyage in late 1870, forcing the captain and his crew to spend the winter camping at Grand Forks. Griggs platted a community in 1875, and Grand Forks was officially incorporated on February 22, 1881.Thousands of settlers were attracted to the Dakota Territory in the 1870s and 1880s for its cheap land, and the population began to rise. Many established small family farms, but some investors bought thousands of acres for bonanza farms, where they supervised the cultivation and harvesting of wheat as a commodity crop. The city grew quickly after the arrival of the Great Northern Railway in 1880 and the Northern Pacific Railway in 1887. In 1883, the University of North Dakota was established, six years before North Dakota was admitted as an independent state born from the Dakota Territory.
