In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: Harry Glicken (March 7, 1958 – June 3, 1991) was an American volcanologist. He researched Mount St. Helens in the United States before and after its 1980 eruption, and was very distraught about the death of fellow volcanologist David A. Johnston, who had switched shifts with Glicken so that the latter could attend an interview. In 1991, while conducting avalanche research on Mount Unzen in Japan, Glicken and fellow volcanologists Katia and Maurice Krafft were killed by a pyroclastic flow. His remains were found four days later, and were cremated in accordance with his parents' request. Glicken and Johnston remain the only American volcanologists known to have died in volcanic eruptions.
Despite a long-term interest in working for the United States Geological Survey, Glicken never received a permanent post there because employees found him eccentric. Conducting independent research from sponsorships granted by the National Science Foundation and other organizations, Glicken accrued expertise in the field of volcanic debris avalanches. He also wrote several major publications on the topic, including his doctoral dissertation based on his research at St. Helens titled "Rockslide-debris Avalanche of May 18, 1980, Mount St. Helens Volcano, Washington" that initiated widespread interest in the phenomenon. Since being published posthumously by Glicken's colleagues in 1996, the report has been acknowledged by many other publications on debris avalanches. Following his death, Glicken was praised by associates for his love of volcanoes and commitment to his field. 
Question: What is the last name of the person who was regarded as eccentric?
[EX A]: Glicken.

[EX Q]: Passage: There are over 20 miles (32 km) of hiking trails at Worlds End State Park. Most of the trails are rocky and steep, so hikers are encouraged to wear proper footgear and to be prepared for icy conditions during the cold winter months. As John Young writes in Hike Pennsylvania, "If you want to do some hiking in the Worlds End region, you should know that hiking here means climbing". Worlds End State Park is open during the winter months for snow mobiling and cross-country skiing. Most of the trails are too steep or rugged for either activity, but the park roads are open, as are trails on surrounding state forest lands.
Loyalsock Trail, often abbreviated LT, is a rugged 59.28-mile (95.40 km) hiking trail that stretches from near Loyalsockville, in Lycoming County on Pennsylvania Route 87 to north of Laporte in Sullivan County, just off U.S. Route 220. This trail follows the ridges and streams of the Loyalsock Creek watershed. The trail is primarily within the boundaries of Loyalsock State Forest and uses some old logging roads and abandoned railroad grades. The Loyalsock Trail was originally blazed in a yellow rectangle with a red stripe, and red can lids with a yellow "LT". Recently, the trail markers have been changed to a yellow disc with a red "LT".
Link Trail is a moderate 8.5-mile (13.7 km) trail marked with a red X on a yellow circle blaze. The trail starts at the Cabin Bridge in the park and follows Loyalsock Creek before it branches off and follows Double Run. The trail then ascends to Canyon Vista and heads out into Loyalsock State Forest where it links up with the Loyalsock Trail at the 55.33-mile (89.05 km) post. The Loyalsock Trail can be followed back for a 17.62 miles (28.36 km) long loop.
Canyon Vista Trail is a 3.5-mile (5.6 km) loop trail with blue blazes that passes through the eastern portion of the park and a stand of ash, sugar maple, and black cherry trees. This trail passes a maze-like jumble of blocky Pottsville Formation rocks known as the Rock Garden, adjacent to Canyon Vista. The vista is at an elevation of 1,750 feet (530 m) and "rewards the hiker with a spectacular view of the Loyalsock Creek gorge".
Worlds End Trail is a 3.25-mile (5.23 km) trail with yellow blazes that begins at the park office and ascends to an overlook of the swimming area. It then crosses the old Pioneer Road, which was used by some of the first settlers to the area, and enters the Loyalsock State Forest, ending at the 37.77-mile (60.78 km) post of the Loyalsock Trail, which can be followed back to the park office to make a loop 11.5 miles (18.5 km) long.
Butternut Trail is a 2.5-mile (4.0 km) trail marked with orange blazes that loops through a hardwood forest and crosses over Butternut Run. Two side trails connect Butternut Trail with the Loyalsock Trail. 
Question: What is the name of the trail that crosses Pioneer Rock?
[EX A]: Worlds End Trail.

[EX Q]: Passage: The Catlins coast often hosts New Zealand fur seals and Hooker's sea lions, and occasionally southern elephant seals can be seen. Several species of penguin also nest along the coast, notably the rare yellow-eyed penguin (hoiho), as do other seabirds including mollymawks and Australasian gannets, and the estuaries of the rivers are home to herons, stilts, godwits and oystercatchers. Bitterns and the threatened fernbird (matata) can also occasionally be seen along the reedy riverbanks.In the forests, endangered birds such as the yellowhead (mohua) and kakariki (New Zealand parakeet) occur, as do other birds such as the tui, fantail (piwakawaka), and kereru (New Zealand pigeon). One of New Zealand's only two native species of non-marine mammal, the long-tailed bat, lives in small numbers within the forests, and several species of lizard are also found locally, including the southern forest gecko.Many species of fish, shellfish, and crustaceans frequent both the local rivers and sea, notably crayfish and paua. Nugget Point in the northern Catlins hosts a particularly rich variety of marine wildlife. The establishment of a marine reserve off the coast here, discussed in 1992, 2004 and 2015, has been controversial. Hector's dolphins can often be seen close to the Catlins coast, especially at Porpoise Bay near Waikawa, which is protected as part of the Catlins Coast Marine Mammal Sanctuary, established in 2008. Migratory southern right whales and humpback whales can be spotted along the coastline during winter. 
Question: What country can southern elephant seals be seen?
[EX A]:
New Zealand.
