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: Consider 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.

Output: In what month is the flow of the WIllamette the lowest?


Input: Consider Input: Passage: In early 1900s Cincinnati, young and beautiful Ray Schmidt works in her father's shop by day and stays out late drinking beer and dancing with various men by night, although her stepmother disapproves. Ray dates for fun, mostly going out with traveling salesmen passing through town, and neither she nor her dates are interested in any permanent attachment. An exception is Kurt Shendler, who owns a bicycle shop near Mr. Schmidt's shop and aspires to get into the automobile business. Kurt is in love with Ray and asks her to marry him, but she refuses because while she likes Kurt, she doesn't return his romantic feelings.
While visiting the train station with Kurt, Ray meets Walter Saxel and the two fall for each other at first sight. Walter soon confesses to Ray that he is actually engaged to another woman in town, Corinne, who comes from a wealthy background and whose mother is friends with his own mother. Nevertheless he has fallen in love with Ray, and asks her to meet him at a local band concert that he will be attending with his mother. Walter hopes to introduce Ray to his mother and perhaps get her approval of the relationship. On the day of the concert, Ray is late arriving because her younger half-sister Freda is suicidal over her boyfriend, Hugo, leaving town. Freda begs Ray to go after Hugo and stop him, threatening to throw herself out a window if Ray does not help. By the time Ray has dealt with Freda's situation and gotten to the concert, it is over, and Ray cannot find Walter or his mother in the departing crowds. Walter, thinking she stood him up, writes her an angry letter and marries Corinne.

Output: What is the first name of the person who tends to her suicidal sister after her sister's boyfriend leaves town?


Input: Consider Input: Passage: In 1943, in preparation for overseas deployment, 400 pilots and 3,600 crewmen of the 351st Bombardment Group assemble at a Colorado air base. Arriving in England, as part of the Eighth Air Force, the 351st BG is welcomed by the Royal Air Force and begins training, attending daily lectures on security. Their first mission flying Boeing B-17 Flying Fortress bombers has the armada departing at 15-second intervals.
The first mission of the 351st on Fortress Europe, after fighting through Luftwaffe defenders, is a success, with all 20 B-17s returning safely back to base. The danger of flying in massed formation, however, is brought home in training, when a collision takes place over the home base. Missions are also not always without casualties and 351st bombers are shot down.  Wounded airmen who make it back to base, are cared for at a nearby hospital. When bombers are all shot up, the ground crew works up to 90-hour periods to put them back into service.
As the mission tallies build, the men partake in activities at the base, including games, socializing and worship. The U.S.O. brings entertainers such as Bob Hope while the Red Cross provides the men with rest and recreation. During special parades, commanders of the 8th Air Force bestow medals for exceptional service and sacrifice.
The 351st participates in a big mission into Germany and after flying for about three hours, the B-17s' fighter escort turns back. As the bombers near their target to drop incendiary and anti-personnel bombs, enemy fighter aircraft appear and intense flak comes up from the ground. After a long battle, the 351st returns to base, ready to fight again until the war is over.


Output: What is the formal name for the group that departs at 15-second intervals on their first mission?
