Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this instance: 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.
Student:
What are the full names of the men who raise the second flag on Mount Suribachi?
