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.

Q: Passage: Worlds End State Park is a 780-acre (316 ha) Pennsylvania state park in Sullivan County, Pennsylvania, in the United States. The park, nearly surrounded by Loyalsock State Forest, is in the Loyalsock Creek valley on Pennsylvania Route 154, in Forks and Shrewsbury Townships southeast of the borough of Forksville. The name Worlds End has been used since at least 1872, but its origins are uncertain. Although it was founded as Worlds End State Forest Park by Governor Gifford Pinchot in 1932, the park was officially known as Whirls End State Forest Park from 1936 to 1943.The park's land was once home to Native Americans, followed by settlers who cleared the forests for subsistence farming and later built sawmills. The second growth forests in and surrounding Worlds End State Park are partially a result of the efforts of the young men of the Civilian Conservation Corps during the Great Depression. They helped overcome the clearcutting of the early 20th century, and built many of the park's facilities, including the cabins that earned it a place on the National Register of Historic Places.
A wide variety of wildlife is found in the park, which is also part of an Important Bird Area. Located in the Endless Mountains region of the dissected Allegheny Plateau, Worlds End has a continental climate and rocks and fossils from the Carboniferous period. It is one of "Twenty Must-See Pennsylvania State Parks" named by the Pennsylvania Department of Conservation and Natural Resources, which describes it as "[v]irtually in a class by itself, this wild, rugged and rustic area seems almost untamed". The park offers year-round recreational opportunities, including environmental education, hiking, camping in tents and cabins, whitewater rafting, swimming, cross-country skiing, snowmobiling, hunting, and fishing.

A: What is the precise modern-day name of the park whose land was once home to Native Americans, followed by settlers who cleared the forests for subsistence farming and later built sawmills?

Q: Passage: The story is set in Rome the early 4th century AD, during the time of the persecution of Christians under the Roman Emperor Diocletian.
The heroine of the book is Fabiola, a young beauty from a noble Roman family. She is spoiled by her father Fabius, who cannot deny her anything. Fabiola seems to have everything, including a superior education in the philosophers, yet under the surface, she is not content with her life. One day, in a fit of rage, she attacks and wounds her slave girl Syra, who is a secret Christian. The proud, spoiled Roman girl is humbled by Syra's humility, maturity and devotion to her in this situation, and a slow transformation begins, which finally culminates in her conversion to Christianity, brought on by Syra and of her own cousin Agnes, whom she adores and dotes on.
Another thread of the story deals with the young boy Pancratius, a pious Christian and son of a martyr, who is himself preparing for martyrdom. Pancratius' nemesis is Corvinus, a bullying schoolmate who is irritated by the young Christian's saintliness. He does everything to bring him and the Christian community of the catacombs of Rome down. This includes the orchestrating of the lynching of their former teacher Cassianus, who is secretly Christian. Yet Pancratius shows his enemy the meaning of Christian forgiveness when he saves his life shortly after Corvinus had Cassianus killed.
Another major villain in the story is the enigmatic Fulvius, an apparently rich young man from the East who soon reveals himself to be a hunter of Christians who turns them in to the authorities for money. His aim on the one hand is to gain the hand of either Fabiola or Agnes, and on the other hand, to uproot the Christian community in Rome. After some dramatic events that reveal his surprising connections to Syra, who is his long-lost younger sister Myriam, Fulvius rejects his evil ways, converts to Christianity and becomes a hermit.

A: Whose life does Pancratius save?

Q: Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.  Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey.

A:
What are the types of whales that use throat pleats to expand the mouth?
