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: The Stooges are wannabe detectives who inadvertently get their chance to crack a case in Scotland. They manage to stumble on a lead concerning the priceless Punjab diamond being stolen by a crook named Dapper. With dreams of becoming genuine detectives, the trio head for Squid McGuffy's cafe asking for the whereabouts of Dapper. They manage to convince everyone at the restaurant that they are actually police.
While searching several rooms above the cafe, the Stooges stumble on Dapper's moll, who hastily hides the Punjab diamond in a candy dish. The boys refuse to leave, suspecting Dapper will eventually show his face. While killing time, Shemp starts to flirt with the moll, and manages to swallow the ice along with some mints from the candy dish. The gal nearly has a nervous breakdown but quickly discovers the Stooges are not actually real detectives. She calls in Dapper and his henchman Muscles and frantically try to pry the diamond out of frazzled Shemp.
After all else fails, Dapper decides to cut him open. Moe and Larry are locked in a closet by Muscles while Shemp is tied down on a close by desk-turned-operating table. As luck would have it, there happen to be a bag of tools in the closet, which Moe and Larry use to saw their way out of the closet, and right into a gorilla's cage on the other side of the wall. The gorilla knocks Moe, Larry, Dapper and Muscles cold. The beast, however, befriends Shemp, and helps him cough up the diamond. Moments later, Shemp explains how he managed to swallow the diamond by actually doing so again.

Ex Output:
Who swallows the Punjab diamond?

Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.

Ex Output:
What name did the company that was  titled "Sadler's Wells Opera" eventually change its name to?

Passage: Grand Teton National Park is located in the northwestern region of the U.S. state of Wyoming. To the north the park is bordered by the John D. Rockefeller, Jr. Memorial Parkway, which is administered by Grand Teton National Park. The scenic highway with the same name passes from the southern boundary of Grand Teton National Park to West Thumb in Yellowstone National Park. Grand Teton National Park covers approximately 310,000 acres (130,000 ha), while the John D. Rockefeller, Jr. Memorial Parkway includes 23,700 acres (9,600 ha).  Most of the Jackson Hole valley and virtually all the major mountain peaks of the Teton Range are within the park. The Jedediah Smith Wilderness of Caribou-Targhee National Forest lies along the western boundary and includes the western slopes of the Teton Range. To the northeast and east lie the Teton Wilderness and Gros Ventre Wilderness of Bridger-Teton National Forest. The National Elk Refuge is to the southeast, and migrating herds of elk winter there. Privately owned land borders the park to the south and southwest. Grand Teton National Park, along with Yellowstone National Park, surrounding National Forests and related protected areas constitute the 18,000,000-acre (7,300,000 ha) (28,000 sq mi (73,000 km2)) Greater Yellowstone Ecosystem. The Greater Yellowstone Ecosystem spans across portions of three states and is one of the largest intact mid-latitude ecosystems remaining on Earth. By road, Grand Teton National Park is 290 mi (470 km) from Salt Lake City, Utah and 550 mi (890 km) from Denver, Colorado.

Ex Output:

How many acres is the larger ecosystem that park located in the northwestern region is a part of?
