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: Ottavio's marriage troubled Alessandro; he struggled with the burden of chastity and entertained fantasies of marrying a princess. He resented his younger brother's arrangement; during the wedding ceremony he "became more deathly pale than death itself, and, so they say, is unable to bear this thing, that he, the first-born, should see himself deprived of such splendid status and of the daughter of an Emperor." In 1546 Paul gave Pier Luigi the duchies of Parma and Piacenza as papal fiefs, a highly political move by the pope: in doing so he gave titles and wealth to Pier and appointed a lord who was subservient and owed a debt of gratitude, guaranteeing that the duchies would remain under papal control. At the same time, Ottavio was posted to the North of Italy to support Charles. By 1546 Ottavio was 22 years old, married to Margaret of Austria and an accomplished and distinguished individual. In 1547 his father was assassinated and Ottavio claimed the dukedom of Parma and Piacenza against the express wishes of both Charles, his father-in-law, and Paul. In doing so, Ottavio acted in opposition to the pope's desire to maintain the duchies as papal fiefs, and to Charles, whom he believed responsible for the plot to assassinate Pier Luigi.Titian was a personal friend of Charles; the commissioning of the portrait was most likely intended by Paul as a signal of allegiance to the emperor. Pressure from reforming monarchs in France and Spain, coupled with a general shift of influence in France's favour, ended the Farnese hold on the papacy soon after Paul's death. Ottavio excelled as a military commander and was awarded the Golden Fleece by the emperor. While the post had been given as a means to strengthen the family position, it did not come without cost. His success bred resentment amongst his family, as he began to see himself unaccountable to Rome.At the time of the portrait Paul had convinced Alessandro to retain the post, hinting that he would later succeed him as pope – an aspiration that was ultimately frustrated. As Alessandro realised the emptiness of the promise he lost confidence in both his grandfather's word and political credibility.

[EX Q]: Passage: In the 1960s, in an undetermined place in the Alps, an eagle couple has two hatching eggs. When both eaglets are born, their mother knows that she must only raise one as their successor. In an ensuing fight with another eagle, the eaglets' father dies when he crashes to the ground. One of the eaglets shortly falls from the nest, and his mother, due by nature to maintain the survivor, ignores the eaglet's cry for help.
In the meantime, forester Danzer meets with a boy named Lukas and his father Keller. They both live in a new house in the mountains, after the death of Maria, mother of Lukas and Keller's wife, as a result of a fire. Keller, gravely afflicted by the death of his wife, fails to live in harmony and understanding with his son, who takes refuge more and more in nature, avoiding contact with his father. As a retreat Lukas constantly goes to the remains of his old house, where he often sees the photograph of his deceased mother.
As Lukas' dog Scout is taking a walk in the forrest, Lukas comes across the eaglet, and Lukas decides to raise him to full health. Lukas takes the eaglet to his old house to take care of him. Danzer also meets the eaglet, and decides to help Lukas for the affection he feels for him.
The forester tells Lukas that the food he has given the eaglet is not good. He also tells him to give sunlight to the eaglet. When a fox sneaks in and kills Keller's hens, he angrily chases Lukas. Lukas, fearful for the safety of the eaglet, goes to his family's hut. Lukas rescues the eaglet from the attacking foxes. As Lukas stays and reads his family's Bible, he comes across the story of Cain and Abel. Aptly fitting the eaglet's own story, Lukas names it Abel.
[EX A]: Who was married to the father of the boy that the forester meets?

[EX Q]: Passage: Ecosystems in the Everglades have been described as both fragile and resilient. Author Michael Grunwald wrote about the observations of the Everglades' first American visitors: "If the Grand Canyon was a breathtaking painting, the Everglades was a complex drama, and everything in it had a role." An estimated 11,000 species of seed-bearing plants and 400 species of land or water vertebrates live in the Everglades, but slight variations in water levels affect many organisms and reshape land formations. The health and productivity of any ecosystem relies on the number of species present: the loss of one species weakens the entire ecosystem.For example, Florida apple snails (Pomacea paludosa)  are an amphibious fresh water mollusk. They have a single gill and lung, and live on stalks of sawgrass in water depths no more than 20 inches (51 cm). They are the primary food of the endangered snail kite (Rostrhamus sociabilis) and limpkin (Aramus guarauna) as well as the raccoon, otter, and young alligator. Apple snails lay their eggs on sawgrass stalks about 6 inches (15 cm) above the water line, and they are intolerant of being submerged for long periods of time. When the eggs hatch, young snails must enter the water quickly or face death. When water levels are too low or rise too quickly while snail eggs are developing, apple snails do not flourish, affecting the many reptiles, mammals, and birds that feed on them. With regard to the ecology of trophic dynamics, or food chains, the 174 species of invertebrates play a vital role in the Everglades. Crayfish, insects, scorpions, and other invertebrates also support a web of animals.
[EX A]:
What is the scientific name of the specific mollusk species that are the primary food of the limpkin and the endangered snail kite?
