TASK 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.
PROBLEM: 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.

SOLUTION: What are the full names of the men who raise the second flag on Mount Suribachi?

PROBLEM: Passage: I was told that I did not learn respect at school. I learned one thing: I learned about self-respect and self-regard for Australia—not about some cultural cringe to a country which decided not to defend the Malayan peninsula, not to worry about Singapore and not to give us our troops back to keep ourselves free from Japanese domination. This was the country that you people wedded yourself to, and even as it walked out on you and joined the Common Market, you were still looking for your MBEs and your knighthoods, and all the rest of the regalia that comes with it.
A fleet was necessary for the defeat of Japan, and eventually a sizeable one, the British Pacific Fleet, did go to the Far East, where it fought alongside the United States Pacific Fleet. The closer relations that developed between the two navies prior to the outbreak of war with Japan, and the alliance that developed from it afterwards, became the most positive and enduring strategic legacy of the Singapore strategy.The Singapore Naval Base suffered little damage in the fighting and became the Imperial Japanese Navy's most important facility outside of the Japanese home islands. The 15-inch guns were sabotaged by the British before the fall of Singapore, and four of them were deemed beyond repair and scrapped by the Japanese. The floating dry dock was scuttled by the British, but raised by the Japanese. It was damaged beyond repair by a raid by Boeing B-29 Superfortresses in February 1945, and ultimately towed out to sea and dumped in 1946. The Royal Navy retook possession of the Singapore base in 1945.

SOLUTION: What did the Royal Navy retake possession of in 1945?

PROBLEM: Passage: After a tornado in Kansas causes a loose gate to knock Dorothy unconscious, she re-appears in the Land of Oz with Toto, and encounters a talking Signpost (voiced by Jack E. Leonard), whose three signs point in different directions, all marked "Emerald City". They later meet Pumpkinhead (voiced by Paul Lynde), the unwilling servant of antagonist Mombi - cousin of the deceased Wicked Witch of the West. Toto chases a cat to a small cottage where Dorothy is captured by Mombi's pet crow (voiced by Mel Blanc) and Mombi (voiced by Ethel Merman) herself. Pumpkinhead sneaks into the house in Mombi's absence, and discovers her creation of green elephants, to use as her army to conquer the Emerald City. Pumpkinhead frees Dorothy, and they flee. After finding Dorothy gone, Mombi threatens that their warning the Scarecrow will not help when her green elephants "come crashing through the gate".
Dorothy and Pumpkinhead acquire Woodenhead Stallion III (voiced by Herschel Bernardi), a former merry-go-round horse (a combination of the Sawhorse from The Marvelous Land of Oz and the title character of the last Oz book of all, Merry Go Round in Oz), who takes them to the Emerald City, where Dorothy warns the Scarecrow (voiced by Mickey Rooney) about Mombi's green elephants. Mombi arrives moments later, and Toto and the Scarecrow are captured. Dorothy, Pumpkinhead, and Woodenhead flee to Tinland to convince the Tin Man (voiced by Danny Thomas, who spoke, and Larry Storch, who sang) to help them. He declines upon being afraid of the green elephants and suggests that they ask the Cowardly Lion (voiced by Milton Berle), who promises to slay the elephants, but suggests consulting Glinda the Good Witch (voiced by Rise Stevens), who appears to them with a "Glinda Bird" that uses its Tattle Tail to show what is occurring at the palace. She then gives Dorothy a little silver box, to open only in the Emerald City, and only in a dire emergency.

SOLUTION:
Who gave Dorothy a little silver box?
