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: In the early 1660s, a building program was initiated to expand the fleet and replace old capital ships. A new flagship was needed to replace the old Kronan from 1632. The felling of vast quantities of timber that were required for the new admiral's ship had already begun in the winter of 1664–65. Swedish historian Kurt Lundgren has estimated that 7–10 hectares (17–25 acres) of hundred-year-old oak forest was required for the hull and several tall, stout pines for the masts and bowsprit.The construction of Kronan began in October 1665, and the hull was launched on 31 July 1668. The English shipwright Francis Sheldon frequently came in conflict with the admiralty over the project. The navy administrators complained that he was unduly delaying the project and was spending too much time on his own private business ventures. The most aggravating contention was Sheldon's extensive and lucrative export of mast timber to England. Sheldon in turn complained about constant delays on the navy's part and lack of funds. When the ship was launched, the slipway turned out to be too small and the rear section of the keel broke off during the launching. The admiralty demanded an explanation, but Sheldon's reply was that the damage was easily mended and that the problem was that the timber had been left to dry too long. The conflict between the Admiralty and Sheldon dragged on for several years and caused constant delays. The sculptures were finished in 1669, but the rigging, tackling, and arming was drawn out a further three years, to 1672. The first occasion that the ship sailed was during the celebrations of Charles XI's accession as monarch in December 1672.
Example Output: What was the shipwright's other business?

Example Input: Passage: The United States Exploring Expedition led by Lieutenant Charles Wilkes was tasked with a vast survey of the Pacific Ocean starting in 1838. In September 1840 they arrived in Honolulu, where repairs to the ships took longer than expected. Wilkes decided to spend the winter in Hawaii and take the opportunity to explore its volcanoes while waiting for better weather to continue the expedition. King Kamehameha III assigned American medical missionary Dr. Gerrit P. Judd to the expedition as a translator.Wilkes sailed to Hilo on the island of Hawaiʻi and decided to climb Mauna Loa first, since it looked easier than Mauna Kea. On December 14 he hired about 200 porters, but after he left he realized only about half the equipment had been taken, so he had to hire more Hawaiians at higher pay. When they reached Kīlauea after two days, their guide Puhano headed off to the established ʻAinapō Trail. Wilkes did not want to head back downhill so he blazed his own way through dense forest directed by a compass. The Hawaiians were offended by the waste of sacred trees which did not help morale. At about 6,000 feet (1,800 m) elevation they established a camp called "Sunday Station" at the edge of the forest.
Two guides joined them at Sunday Station: Keaweehu, "the bird-catcher" and another whose Hawaiian name is not recorded, called "ragsdale". Although Wilkes thought he was almost to the summit, the guides knew they were less than halfway up. Since there was no water at Sunday Station, porters had to be sent back ten miles (16 km) to a lava tube on ʻAinapō Trail which had a known supply. After an entire day replenishing stocks, they continued up to a second camp they called "Recruiting Station" at about 9,000 feet (2,700 m) elevation. After another full day's hike they established "Flag Station" on December 22, and by this time were on the ʻAinapō Trail. Most of the porters were sent back down to get another load.
Example Output: What is the full name of the man that offended native Hawaiians by wasting sacred trees?

Example Input: Passage: While on a hunting trip on Loyalsock Creek north of the park in 1850, brothers Elijah and Clemuel Ricketts were frustrated at having to spend the night on a hotel's parlor floor. In 1851 or 1853 they bought 5,000 acres (2,000 ha), including what is now Lake Ganoga and some of the park, as their own hunting preserve, and built a stone house on the lake shore by 1852 or 1855. The stone house served as their lodge and as a tavern; it was known as "Ricketts Folly" for its isolated location in the wilderness. Clemuel died in 1858 and Elijah bought his share of the land and house. The Ricketts family was not aware of the glens and their waterfalls until about 1865, when they were discovered by two guests from the stone house who went fishing and wandered down Kitchen Creek.Elijah's son Robert Bruce Ricketts, for whom the park is named, joined the Union Army as a private at the outbreak of the American Civil War and rose through the ranks to become a colonel in the artillery. After the war, R. Bruce Ricketts returned to Pennsylvania and in 1869 began purchasing the land around the lake from his father. By 1873 he controlled or owned 66,000 acres (27,000 ha), and eventually this grew to more than 80,000 acres (32,000 ha), including the glens and waterfalls and most of the park.While the stone house had served as a home and inn since its construction, in 1872 R. Bruce Ricketts built a three-story wooden addition north of the house. The addition used lumber from a sawmill Ricketts and his partners operated from 1872 to 1875, about 0.5 miles (0.8 km) southeast of the stone house. The North Mountain House hotel opened in 1873; Ricketts' brother Frank, for whom a park waterfall is named, managed it from then until 1898. Many of the hotel's guests were Ricketts' friends and relations, who arrived after school let out in June and stayed all summer until school resumed in September. In 1876 and 1877, Ricketts ran the first summer school in the United States at his house and hotel; one of the teachers was Joseph Rothrock, later known as the "Father of Forestry" in Pennsylvania.

What is the last name of the person who died in 1858?
