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.

[EX Q]: 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 A]: What are the full names of the men who raise the second flag on Mount Suribachi?

[EX Q]: Passage: Located on the Gulf of Antalya on the Anatolian coastal plain of Pamphylia, the town is situated between the Taurus Mountains to the north and the Mediterranean Sea, and is part of the Turkish riviera, occupying roughly 70 kilometres (43 mi) of coastline. From west to east, the Alanya district is bordered by the Manavgat district along the coast, the mountainous Gündoğmuş inland, Hadim and Taşkent in the Province of Konya, Sarıveliler in the Province of Karaman, and the coastal Gazipaşa district. Manavgat is home to the ancient cities of Side and Selge. East of the city, the Dim River flows from the mountains in Konya on a south-west route into the Mediterranean.
The Pamphylia plain between the sea and the mountains is an isolated example of an Eastern Mediterranean conifer-sclerophyllous-broadleaf forest, which include Lebanon Cedar, evergreen scrub, fig trees, and black pine. The Alanya Massif refers to the area of metamorphic rocks east of Antalya. This formation is divided into three nappes from lowest to highest, the Mahmutlar, the Sugözü, and the Yumrudağ. The similar lithology extends beneath the city in a tectonic window. Bauxite, an aluminum ore, is common to the area north of city, and can be mined.
The town is divided east–west by a rocky peninsula, which is the distinctive feature of the city. The harbor, city center, and Keykubat Beach, named after the Sultan Kayqubad I, are on the east side of the peninsula. Damlataş Beach, named for the famous "dripping caves", and Kleopatra Beach are to the west. The name "Cleopatra" possibly derives from either the Ptolemaic princess' visit here or the area's inclusion in her dowry to Mark Antony. Atatürk Bulvarı, the main boulevard, runs parallel to the sea, and divides the southern, much more touristic side of Alanya from the northern, more indigenous side that extends north into the mountains. Çevre Yolu Caddesi, another major road, encircles the main town to the north.
[EX A]: What is the aluminum ore that can be mined in the town on the Turkish riviera?

[EX Q]: Passage: In 1967, Pennsylvania leased the reactor complex to the Nuclear Materials and Equipment Corporation (NUMEC), which already had a federal license to work with nuclear materials. NUMEC, which soon became a subsidiary of Atlantic-Richfield Corporation (ARCO), set up a large irradiator in what had been the reactor pool. The irradiator contained over 1 million curies of cobalt-60 to produce intense gamma rays, which were used to sterilize medical equipment and irradiate food and wood. In the spring of 1967 the state had concluded that radiation contamination at the Quehanna site "could never be completely cleaned up", and so was glad to find a tenant with nuclear experience.
A group of NUMEC employees discovered that irradiating hardwood treated with plastics produced very durable flooring. In 1978 they formed PermaGrain Products, Inc. as a separate company from ARCO, and purchased the rights to the process as well as "the main irradiator, a smaller shielded irradiator and related equipment". PermaGrain sold the flooring for use in basketball courts and gymnasiums, and was the longest occupant of the Quehanna facility, operating there from 1978 to December 2002. PermaGrain also let Neutron Products, Inc., a Maryland company, do cobalt-60 work in its hot cells, which required an amendment of their license from the Nuclear Regulatory Commission (NRC, the successor to the AEC).In 1993, strontium-90 contamination in the reactor facility led the NRC to require PermaGrain to begin decontamination work, and the Pennsylvania DEP commissioned a "site characterization study". In 1998, a firm named NES began the cleanup work; they changed their name to Scientech in 1999 and to EnergySolutions in 2006. The cleanup was originally estimated to take six months; by 2006 it had taken 8 years and cost $30 million. According to the Pennsylvania Department of Environmental Protection's (DEP) Bureau of Radiation Protection: "Inadequate characterization of the site and the presence of ongoing industrial operations resulted in many project delays and increased costs." The hot cells proved to have more radioactive sources than originally thought. In October 1998 a Scientech worker doing decontamination cut a tube in hot cell number 4, which accidentally released strontium-90 into PermaGrain's work area. As a result, a robot had to be constructed to remove 3,000 curies of cobalt-60 in two of the hot cells, dismantle cell 4, and decontaminate the rest remotely.
[EX A]:
What was accidentally released in October 1998 in the facility that was owned by the company that sold flooring for use in basketball courts?
