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.

Question: Passage: Dr. John Harvey Kellogg opened a sanitarium in Battle Creek, Michigan, where he practiced his unusual methods for maintaining health, including colonic irrigation, electrical stimulus and sexual abstinence, vegetarianism and physical exercise. The sanitarium attracts well-to-do patients including William and Eleanor Lightbody, who are suffering from poor health following the death of their child. On their way to Battle Creek they meet Charles Ossining, hoping to make a fortune by exploiting the fad for health food cereals.
Ossining finds a partner in Goodloe Bender. Having enlisted the services of George Kellogg, the doctor's estranged adopted son, they attempt to produce "Kellogg's Perfo Flakes." 
In the sanitarium, Will Lightbody is separated from his wife, and is soon harboring lustful thoughts toward Nurse Graves and patient Ida Muntz. His wife Eleanor, meanwhile, befriends Virginia Cranehill, who has a modern attitude toward sexual pleasure, influenced by the works of Dr. Lionel Badger. Will eventually succumbs to Ida Muntz's charms. Later he learns that Ida has died during treatment. Following the death of a patient in the sinusoidal bath, and the discovery of yet another death, Will suffers a breakdown, flees the sanitarium, gets drunk and eats meat. At a restaurant, he meets Ossining, and agrees to invest $1,000 in his health food business. Will returns drunk to the sanitarium, where he is reprimanded by Dr. Kellogg and is abandoned by a distraught Eleanor.  
Ossining's business is a disaster, with no edible product. He and the partners resort to stealing Kellogg's cornflakes and repackaging them in their own boxes. Ossining meets his aunt, his sole investor, on visiting day at Kellogg's sanitarium, and is there exposed as a fraud and arrested.

Answer: What is the first real name of the person whose wife befriends Virginia Cranehill?


Question: Passage: In Western Europe, some of the older Roman elite families died out while others became more involved with ecclesiastical than secular affairs. Values attached to Latin scholarship and education mostly disappeared, and while literacy remained important, it became a practical skill rather than a sign of elite status. In the 4th century, Jerome (d. 420) dreamed that God rebuked him for spending more time reading Cicero than the Bible. By the 6th century, Gregory of Tours (d. 594) had a similar dream, but instead of being chastised for reading Cicero, he was chastised for learning shorthand. By the late 6th century, the principal means of religious instruction in the Church had become music and art rather than the book. Most intellectual efforts went towards imitating classical scholarship, but some original works were created, along with now-lost oral compositions. The writings of Sidonius Apollinaris (d. 489), Cassiodorus (d. c. 585), and Boethius (d. c. 525) were typical of the age.Changes also took place among laymen, as aristocratic culture focused on great feasts held in halls rather than on literary pursuits. Clothing for the elites was richly embellished with jewels and gold. Lords and kings supported entourages of fighters who formed the backbone of the military forces. Family ties within the elites were important, as were the virtues of loyalty, courage, and honour. These ties led to the prevalence of the feud in aristocratic society, examples of which included those related by Gregory of Tours that took place in Merovingian Gaul. Most feuds seem to have ended quickly with the payment of some sort of compensation. Women took part in aristocratic society mainly in their roles as wives and mothers of men, with the role of mother of a ruler being especially prominent in Merovingian Gaul. In Anglo-Saxon society the lack of many child rulers meant a lesser role for women as queen mothers, but this was compensated for by the increased role played by abbesses of monasteries. Only in Italy does it appear that women were always considered under the protection and control of a male relative.

Answer: What type of ties led to feuds in aristocratic society?


Question: 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.

Answer:
What is the scientific name of the specific mollusk species that are the primary food of the limpkin and the endangered snail kite?
