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.

Example Input: Passage: The St. Johns River (Spanish: Río San Juan) is the longest river in the U.S. state of Florida and its most significant one for commercial and recreational use. At 310 miles (500 km) long, it flows north and winds through or borders twelve counties. The drop in elevation from headwaters to mouth is less than 30 feet (9 m); like most Florida waterways, the St. Johns has a very low flow rate 0.3 mph (0.13 m/s) and is often described as "lazy". Numerous lakes are formed by the river or flow into it, but as a river its widest point is nearly 3 miles (5 km) across. The narrowest point is in the headwaters, an unnavigable marsh in Indian River County. The St. Johns drainage basin of 8,840 square miles (22,900 km2) includes some of Florida's major wetlands. It is separated into three major basins and two associated watersheds for Lake George and the Ocklawaha River, all managed by the St. Johns River Water Management District.
A variety of people have lived on or near the St. Johns, including Paleo-indians, Archaic people, Timucua, Mocama, French and Spanish settlers, Seminoles, slaves and freemen, Florida crackers, land developers, tourists and retirees. It has been the subject of William Bartram's journals, Marjorie Kinnan Rawlings' books, and Harriet Beecher Stowe's letters home. Although Florida was the location of the first permanent European settlement in what would become the United States, it was the last U.S. territory on the east coast to be developed; it remained an undeveloped frontier into the 20th century. When attention was turned to the state, however, much of the land was rapidly overdeveloped in a national zeal for progress. The St. Johns, like many Florida rivers, was altered to make way for agricultural and residential centers. It suffered severe pollution and human interference that has diminished the natural order of life in and around the river. In all, 3.5 million people live within the various watersheds that feed into the St. Johns River. The St. Johns, named one of 14 American Heritage Rivers in 1998, was number 6 on a list of America's Ten Most Endangered Rivers in 2008. Restoration efforts are under way for the basins around the St. Johns as Florida continues to deal with population increases in the river's vicinity.
Example Output: What state remained an undeveloped frontier into the 20th century?

Example Input: Passage: Years ago, a mob boss named Lucio Malatesta pinned the murder of rival Sammy Carboni on another rival named Angelo Allieghieri, which led to Sammy's son Gianni vowing revenge.
Frankie Delano has spent his life safeguarding Angelo as well as Angelo's daughter, Jennifer Barrett, whose unsavory husband Kip Barrett has had their young son Rawley placed in a boarding school against Jennifer's wishes.
Jennifer was raised by her adoptive parents Whitney Towers and Peggy Towers and is not aware that Angelo is her father.
After Angelo is killed in a restaurant by a hit man named Bruno, Frankie introduces himself, tells Jennifer who he is and what he has been doing.
A neurotic mess, Jennifer can barely handle the news that Kip is a philanderer, let alone the revelation that she is a gangster's daughter. But a DVD prepared by Angelo in the case of just such an event convinces Jennifer that it's the truth.
Jennifer certainly doesn't want a full-time bodyguard, even Frankie. She ditches Kip and then falls for Italian romance novelist Marcello, who lectures at her book club. Frankie has suspicions about Marcello, but his job is to stay on the sidelines.
Frankie rescues Jennifer from a string of attacks. With many of Angelo's enemies, including Lucio Malatesta, terminated, Frankie allows her to visit Italy with Marcello. But it turns out that Marcello is actually Gianni Carboni, who had Angelo killed. And now Gianni plans to kill Jennifer.
It is up to Frankie to protect her one more time.
Example Output: What is the first name of the person that Frankie must protect one more time?

Example Input: Passage: During World War I, the wily and attractive French POW Sergeant Dumaine is sequestered in a prison camp near the castle of a prideful Prussian nobleman and military general, Count Reichendorf, who lives for the day that his four sons will march triumphantly into Paris. Having lost three sons to the French and English armies, and left with only one son, Dietrich, Reichendorf laments the days when his family made Prussia "the might of land." He is forced to recruit military men from the prison camp. Axelle, the daughter of one of the sons, who became his ward when her parents died, lives in the Reichendorf castle and makes periodic goodwill visits to the prison compound, where she first encounters Dumaine. Captain Ebbing, the martinet and disfigured prison commandant, develops an interest in Axtelle. He courts her, but Axelle shows little interest in him, and when he reminds her how he dazzled her before he went into battle, she rejects his affections and tells him that she is engaged to Dietrich. Ebbing pleads with her, insisting that his love for her is more intense and enduring than that of any other man, but she is not swayed.
Ebbing soon puts Dumaine and the other prisoners to work at the unpleasant task of burial detail. When Dumaine, Fichet and other prisoners escape by overpowering the guards, they break into the Reichendorf castle and take refuge there, but are soon discovered by Axelle and taken back to the prison. One day, after noticing billows of smoke coming from the castle, Dumaine heroically rushes into the castle and puts out a kitchen fire. In gratitude for his valor, Ebbing commissions Dumaine, an electrical engineer by profession, to wire the castle. Dumaine's new assignment puts him in close contact with Axelle, and they soon become friends. After one month, Axelle begins to trust Dumaine and suggests that he remove his prison number from his uniform.
Example Output:
Who does the Prussian nobleman want to march into Paris?
