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.

Passage: As three US servicemen – Marine Private First Class Ira Hayes, Private First Class Rene Gagnon, and Navy Corpsman John "Doc" Bradley – are feted as heroes in a war bond drive, they reflect on their experiences via flashback.
After training at Camp Tarawa in Hawaii, the 28th Marine Regiment 5th Marine Division sails to invade Iwo Jima. The Navy bombards suspected Japanese positions for three days. Sergeant Mike Strank is put in charge of Second Platoon.
The next day, February 19, 1945, the Marines land in Higgins boats and LVTs. The beaches are silent and Private First Class Ralph "Iggy" Ignatowski wonders if the defenders are all dead before Japanese heavy artillery and machine guns open fire on the advancing Marines and the Navy ships. Casualties are heavy, but the beaches are secured.
Two days later, the Marines attack Mount Suribachi under a rain of Japanese artillery and machine gun fire, as the Navy bombards the mountain. Doc saves the lives of several Marines under fire, which later earns him the Navy Cross. The mountain is eventually secured.
On February 23, the platoon under command of Sergeant Hank Hansen reaches the top of Mount Suribachi and hoists the United States flag to cheers from the beaches and the ships. Secretary of the Navy James Forrestal, who witnesses the flag raising as he lands on the beach, requests the flag for himself. Colonel Chandler Johnson decides his 2nd Battalion deserves the flag more. Rene is sent up with Second Platoon to replace the first flag with a second one for Forrestal to take. Mike, Doc, Ira, Rene, and two other Marines (Corporal Harlon Block and Private First Class Franklin Sousley) are photographed by Joe Rosenthal as they raise the second flag.
On March 1, the Second Platoon is ambushed from a Japanese machine gun nest. During the fight over the nest, Mike is hit by a U.S. Navy shell and dies from his wounds. Later that day, Hank is shot in the chest and dies, and Harlon is killed by machine gun fire.

Ex Output:

Passage: Set during the Middle Ages in Europe, a king is seeking a brave warrior to kill a giant which has been terrorizing the small kingdom. There is much discussion in the village, but no one is willing to take on the task. Nearby in the same village, a young peasant tailor kills seven flies at once while at his work, and accidentally interjects several other peasants' discussion of the problems with the giant to brag loudly about his accomplishment:

Peasant (to his friends): "Say, did you ever kill a giant?"
Mickey (interjecting unwittingly): "I killed seven with one blow!"Gossip that Mickey has killed seven giants with one blow quickly spreads around the kingdom. The king summons Mickey, and asks if he really "killed seven at one blow". Mickey goes into an elaborate re-telling of how he killed the seven (flies, not giants as the king believes), which impresses the king enough to appoint Mickey "Royal High Killer of the Giant". Upon learning the misunderstanding, all of Mickey's confidence disappears and he attempts to stammer his way out of the assignment. The king offers Mickey both vast riches and the hand of his only daughter, Princess Minnie, in marriage if he can kill (or at least subdue) the giant. Smitten with the princess, Mickey proclaims that he'll "cut [the giant] down to my size", and sets off for the giant's lair.
After only a few minutes, however, he is ready to turn back and give up, but the townspeople and Minnie are counting on him. "Gosh," Mickey sighs to himself, wondering what to do. "I dunno how to catch a giant.".

Ex Output:
Who kills seven flies at once while at work?

Passage: Manitoba ( (listen)) is a province at the longitudinal centre of Canada. It is often considered one of the three prairie provinces (with Alberta and Saskatchewan) and is Canada's fifth-most populous province with its estimated 1.3 million people. Manitoba covers 649,950 square kilometres (250,900 sq mi) with a widely varied landscape, stretching from the northern oceanic coastline to the southern border with the United States. The province is bordered by the provinces of Ontario to the east and Saskatchewan to the west, the territories of Nunavut to the north, and Northwest Territories to the northwest, and the U.S. states of North Dakota and Minnesota to the south.
Aboriginal peoples have inhabited what is now Manitoba for thousands of years. In the late 17th century, fur traders arrived on two major river systems, what is now called the Nelson in northern Manitoba and in the southeast along the Winnipeg River system. A Royal Charter in 1670 granted all the lands draining into Hudson's Bay to the British company and they administered trade in what was then called Rupert's Land. During the next 200 years, communities continued to grow and evolve, with a significant settlement of Michif in what is now Winnipeg. The assertion of Métis identity and self-rule culminated in negotiations for the creation of the province of Manitoba. There are many factors that led to an armed uprising of the Métis people against the Government of Canada, a conflict known as the Red River Rebellion. The resolution of the assertion of the right to representation led to the Parliament of Canada passing the Manitoba Act in 1870 that created the province.
Manitoba's capital and largest city, Winnipeg, is the eighth-largest census metropolitan area in Canada. Other census agglomerations in the province are Brandon, Steinbach, Portage la Prairie, and Thompson.
