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 Input: Passage: With an average flow at the mouth of about 37,400 cubic feet per second (1,060 m3/s), the Willamette ranks 19th in volume among rivers in the United States and contributes 12 to 15 percent of the total flow of the Columbia River. The Willamette's flow varies considerably season to season, averaging about 8,200 cubic feet per second (230 m3/s) in August to more than 79,000 cubic feet per second (2,200 m3/s) in December.
The U.S. Geological Survey (USGS) operates five stream gauges along the river, at Harrisburg, Corvallis, Albany, Salem, and Portland. The average discharge at the lowermost gauge, near the Morrison Bridge in Portland, was 33,220 cubic feet per second (941 m3/s) between 1972 and 2013. Located at river mile (RM) 12.8 or river kilometer (RK) 20.6, the gauge measures the flow from an area of 11,200 square miles (29,000 km2), roughly 97 percent of the Willamette basin. The highest flow recorded at this station was 420,000 cubic feet per second (11,893 m3/s) on February 9, 1996, during the Willamette Valley Flood of 1996, and the minimum was 4,200 cubic feet per second (120 m3/s) on July 10, 1978. The highest recorded flow of 635,000 cubic feet per second (18,000 m3/s) for the Willamette at a different gauge in Portland occurred during a flood in 1861. This and many other large flows preceded the Flood Control Act of 1936 and dam construction on the Willamette's major tributaries.The river below Willamette Falls, 26.5 miles (42.6 km) from the mouth, is affected by semidiurnal tides, and gauges have detected reverse flows (backwards river flows) upstream from Ross Island at RM 15 (RK 24). The National Weather Service issues tide forecasts for the river at the Morrison Bridge.
Example Output: In what month is the flow of the WIllamette the lowest?

Example Input: Passage: A 11-year-old orphan, Anne Shirley, is living in servitude with the cruel Hammond family in Nova Scotia. However, when Mr. Hammond dies, Anne is sent to an orphanage where she eventually receives the wonderful news that she has been adopted by a couple on Prince Edward Island. Upon arriving in P.E.I, Anne is met at the train station by an elderly Matthew Cuthbert who is surprised to find a girl there instead of a boy.
Matthew and his sister Marilla had requested a boy to help them with the farm chores. He decides that he couldn't very well just leave the girl at the train station. Matthew takes Anne to meet Marilla, and on the buggy ride home, becomes completely smitten with the red-haired orphan girl.
When Anne Shirley arrives at the Cuthberts' farm, called "Green Gables", she is a precocious, romantic child desperate to be loved and highly sensitive about her red hair and homely looks. In her own unique headstrong manner, Anne manages to insult the town gossip, Rachel Lynde, in a dispute over her looks; smash her slate over Gilbert Blythe's head when he calls her "Carrots" on her first day of school; and accidentally dyes her hair green in an effort to turn her red hair black and salvage her wounded pride.
Marilla Cuthbert is shocked and beside herself to know how she will ever cope with this sensitive, headstrong child so desperate to fit in. But shy, gentle Matthew is always there to defend Anne and hold her up on a pedestal.
It seems like Anne is destined to cultivate disaster. She becomes "bosom" friends with Diana Barry from across the pond and succeeds in getting Diana drunk by accidentally serving currant wine instead of raspberry cordial at a tea party. Diana's mother and Rachel Lynde turn on Marilla for making wine in the first place. Anne moves from one mishap to the next as her wild imagination and far-fetched antics combine to constantly land her in trouble.
Example Output: What are the first names of the two people who requested a boy to help them with farm chores?

Example Input: Passage: Human habitation in the Sierra Nevada region of California reaches back 8,000 to 10,000 years ago. Historically attested Native American populations, such as the Sierra Miwok, Mono and Paiute, belong to the Uto-Aztecan and Utian phyla.
In the mid-19th century, a band of Native Americans called the Ahwahnechee lived in Yosemite Valley. The California Gold Rush greatly increased the number of non-indigenous people in the region. Tensions between Native Americans and white settlers escalated into the Mariposa War. As part of this conflict, settler James Savage led the Mariposa Battalion into Yosemite Valley in 1851, in pursuit of Ahwaneechees led by Chief Tenaya. Accounts from the battalion, especially from Dr. Lafayette Bunnell, popularized Yosemite Valley as a scenic wonder.
In 1864, Yosemite Valley and the Mariposa Grove of giant sequoia trees were transferred from federal to state ownership. Yosemite pioneer Galen Clark became the park's first guardian. Conditions in Yosemite Valley were made more hospitable to people and access to the park was improved in the late 19th century. Naturalist John Muir and others became increasingly alarmed about the excessive exploitation of the area. Their efforts helped establish Yosemite National Park in 1890. Yosemite Valley and the Mariposa Grove were added to the national park in 1906.
The United States Army had jurisdiction over the national park from 1891 to 1914, followed by a brief period of civilian stewardship. The newly formed National Park Service took over the park's administration in 1916. Improvements to the park helped to increase visitation during this time. Preservationists led by Muir and the Sierra Club failed to save Hetch Hetchy Valley from becoming a reservoir in 1923. In 1964, 89 percent of the park was set aside in a highly protected wilderness area, and other protected areas were added adjacent to the park. The once-famous Yosemite Firefall, created by pushing red hot embers off a cliff near Glacier Point at night, was discontinued in the mid-to-late 20th century along with other activities that were deemed to be inconsistent with protection of the national park.
Example Output:
What event happened because to the California Gold Rush?
