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: The term "Gadget" was a laboratory euphemism for a bomb, from which the laboratory's weapon physics division, "G Division", took its name in August 1944. At that time it did not refer specifically to the Trinity Test device as it had yet to be developed, but once it was, it became the laboratory code name. The Trinity Gadget was officially a Y-1561 device, as was the Fat Man used a few weeks later in the bombing of Nagasaki. The two were very similar, with only minor differences, the most obvious being the absence of fuzing and the external ballistic casing. The bombs were still under development, and small changes continued to be made to the Fat Man design.To keep the design as simple as possible, a near solid spherical core was chosen rather than a hollow one, although calculations showed that a hollow core would be more efficient in its use of plutonium. The core was compressed to prompt super-criticality by the implosion generated by the high explosive lens. This design became known as a "Christy Core" or "Christy pit" after physicist Robert F. Christy, who made the solid pit design a reality after it was initially proposed by Edward Teller. Along with the pit, the whole physics package was also informally nicknamed "Christy['s] Gadget".Of the several allotropes of plutonium, the metallurgists preferred the malleable δ phase. This was stabilized at room temperature by alloying it with gallium. Two equal hemispheres of plutonium-gallium alloy were plated with silver, and designated by serial numbers HS-1 and HS-2. The 6.19-kilogram (13.6 lb) radioactive core generated 15 W of heat, which warmed it up to about 100 to 110 °F (38 to 43 °C), and the silver plating developed blisters that had to be filed down and covered with gold foil; later cores were plated with nickel instead. The Trinity core consisted of just these two hemispheres. Later cores also included a ring with a triangular cross-section to prevent jets forming in the gap between them.

A: What is the code name of the device that was developed after it had a code name?

Q: Passage: On 21 January 1818, Friedrich married Caroline Bommer, the twenty-five-year-old daughter of a dyer from Dresden. The couple had three children, with their first, Emma, arriving in 1820.  Physiologist and painter Carl Gustav Carus notes in his biographical essays that marriage did not impact significantly on either Friedrich's life or personality, yet his canvasses from this period, including Chalk Cliffs on Rügen—painted after his honeymoon—display a new sense of levity, while his palette is brighter and less austere. Human figures appear with increasing frequency in the paintings of this period, which Siegel interprets as a reflection that "the importance of human life, particularly his family, now occupies his thoughts more and more, and his friends, his wife, and his townspeople appear as frequent subjects in his art."Around this time, he found support from two sources in Russia. In 1820, the Grand Duke Nikolai Pavlovich, at the behest of his wife Alexandra Feodorovna, visited Friedrich's studio and returned to Saint Petersburg with a number of his paintings, an exchange that began a patronage that continued for many years. Not long thereafter, the poet Vasily Zhukovsky, tutor to Alexander II, met Friedrich in 1821 and found in him a kindred spirit. For decades Zhukovsky helped Friedrich both by purchasing his work himself and by recommending his art to the royal family; his assistance toward the end of Friedrich's career proved invaluable to the ailing and impoverished artist. Zhukovsky remarked that his friend's paintings "please us by their precision, each of them awakening a memory in our mind."Friedrich was acquainted with Philipp Otto Runge, another leading German painter of the Romantic period. He was also a friend of Georg Friedrich Kersting, and painted him at work in his unadorned studio, and of the Norwegian painter Johan Christian Clausen Dahl (1788–1857). Dahl was close to Friedrich during the artist's final years, and he expressed dismay that to the art-buying public, Friedrich's pictures were only "curiosities". While the poet Zhukovsky appreciated Friedrich's psychological themes, Dahl praised the descriptive quality of Friedrich's landscapes, commenting that "artists and connoisseurs saw in Friedrich's art only a kind of mystic, because they themselves were only looking out for the mystic... They did not see Friedrich's faithful and conscientious study of nature in everything he represented".During this period Friedrich frequently sketched memorial monuments and sculptures for mausoleums, reflecting his obsession with death and the afterlife; he even created designs for some of the funerary art in Dresden's cemeteries. Some of these works were lost in the fire that destroyed Munich's Glass Palace (1931) and later in the 1945 bombing of Dresden.

A: What is the full name of the person whose assistance toward the end of Friedrich's career proved invaluable to the ailing and impoverished artist?

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?
