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.

Passage: Leonard Harrison State Park is a 585-acre (237 ha) Pennsylvania state park in Tioga County, Pennsylvania, in the United States. It is on the east rim of the Pine Creek Gorge, also known as the Grand Canyon of Pennsylvania, which is 800 feet (240 m) deep and nearly 4,000 feet (1,200 m) across here. It also serves as headquarters for the adjoining Colton Point State Park, its sister park on the west rim of the gorge. Leonard Harrison State Park is known for its views of the Pine Creek Gorge, and offers hiking, fishing and hunting, whitewater boating, and camping. The park is in Shippen and Delmar Townships, 10 miles (16 km) west of Wellsboro at the western terminus of Pennsylvania Route 660.
Pine Creek flows through the park and has carved the gorge through five major rock formations from the Devonian and Carboniferous periods. Native Americans once used the Pine Creek Path along the creek. The path was later used by lumbermen, and then became the course of a railroad from 1883 to 1988. Since 1996, the 63.4-mile (102.0 km) Pine Creek Rail Trail has followed the creek through the park. The Pine Creek Gorge was named a National Natural Landmark in 1968 and is also protected as a Pennsylvania State Natural Area and Important Bird Area, while Pine Creek is a Pennsylvania Scenic and Wild River. The gorge is home to many species of plants and animals, some of which have been reintroduced to the area.
Although the Pine Creek Gorge was clearcut in the 19th and early 20th centuries, it is now covered by second growth forest, thanks in part to the conservation efforts of the Civilian Conservation Corps (CCC) in the 1930s. The park is named for Leonard Harrison, a Wellsboro lumberman who cut the timber there, then established the park, which he donated to the state in 1922. The CCC improved the park and built many of its original facilities. Since a successful publicity campaign in 1936, the park has been a popular tourist destination and attracts hundreds of thousands of visitors each year. Leonard Harrison State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of Parks for its "25 Must-See Pennsylvania State Parks" list, which praised its "spectacular vistas and a fabulous view of Pine Creek Gorge, also known as Pennsylvania's Grand Canyon".
What is the name of the place whose sister park is on the west rim of the gorge?

Passage: One of Greenway's finest works, St James' is listed on the (now defunct) Register of the National Estate. It has been called an "architectural gem" and was featured by Dan Cruickshank in the BBC television series Around the World in 80 Treasures. From 1966 to 1993 the spire of St James' appeared on the Australian Australian ten-dollar note among other Greenway buildings. In 1973, the church appeared on a 50 cent postage stamp, one of four in a series illustrating Australian architecture issued to commemorate the opening of the Sydney Opera House. The Old Supreme Court building, also designed by Greenway with alternations by others, located next to the church is of the same date. Across the square is Greenway's "masterpiece", the UNESCO World Heritage listed-Hyde Park Barracks, designed to align with the church. Beside the barracks stands Sydney's oldest public building, part of the General Hospital built in 1811 and now known as the Mint Building. Separated from the Mint by the present-day Sydney Hospital is Parliament House, Sydney, of which the central section is a further part of the early hospital, and is now home to the New South Wales State Parliament.The church was constructed between 1820 and 1824 with later additions made in 1834 by John Verge who designed the vestries at the eastern end. Apart from these vestries, which retain the established style and proportions, the church externally remains "fine Georgian" much as Greenway conceived it. Relying on the "virtues of simplicity and proportion to achieve his end", Greenway maintained the classical tradition, unaffected by the Revivalist styles that were being promoted in London at the time he arrived in the colony. He planned the church to align with his earlier Hyde Park Barracks, constructed in 1817–19. The two buildings have similar proportions, pilasters and gables and together constitute an important example of town-planning. Before the advent of high-rise buildings, the 46-metre (150 ft) spire used to "serve as a guide for mariners coming up Port Jackson".St James' originally took the form of a simple rectangular block, without transepts or chancel, with a tower at the western end and a classical portico of the Doric order on either side. To this has been added Verge's vestry framed by two small porticos, and a similar portico as an entrance to the tower. The church is built of local brick, its walls divided by brick pilasters into a series of bays. The walls are pierced by large windows with round arched heads in a colour that separates and defines them against the walls. The roof carries over the end walls with the gable forming triangular pediments of classical proportions carrying a cornice across the eaves line. Thus the architectural treatment on the side walls is continued around the end walls.
What is the name of that which is called an architectural gem and was featured by Dan Cruickshank in a BBC television series?

Passage: The chain of craters has been the subject of several writers and naturalists. Mark Twain visited Mono Basin in the 1860s and wrote about Mono Lake, but did not mention any of the Mono–Inyo Craters except for the lake's two volcanic islands. He wrote in Roughing It (1872) that the lake was in a "lifeless, hideous desert ..." that was the "loneliest spot on earth ... little graced with the picturesque."
Naturalist John Muir explored the area in 1869. He described the "Mono Desert" as a "... country of wonderful contrasts. Hot deserts bounded by snow-laden mountains,—cinders and ashes scattered on glacier-polished pavements,—frost and fire working together in the making of beauty. In the lake are several volcanic islands, which show that the waters were once mingled with fire."  Muir described the Mono Craters as "... heaps of loose ashes that have never been blest by either rain or snow ..."In the spring of 1881 and the fall of 1882, geologist Israel Russell studied the area as a side-trip during his field research of Lake Lahontan, a now dry lake that covered much of nearby Nevada during the last glacial period. His Quaternary History of the Mono Valley (1889), which included a topographic survey by Willard D. Johnson, was the first thorough scientific description of Mono Lake and its volcanic features.
Russell named the Mono Craters and wrote: "The attention of every one who enters Mono Valley is at once attracted by the soft, pleasing colors of these craters as well as by the symmetry and beauty of their forms. They are exceptional features in the scenery of the region, and are rendered all the more striking by their proximity to the angular peaks and rugged outlines of the High Sierra.".

What is the name of the place that has two volcanic islands?
