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: Three men rob a millionaire of diamonds aboard an airliner in flight. When Police Superintendent Benting tries to intervene, Jack Drake, another passenger, knocks him out to save him from being shot. The thieves force the pilot to land so they can dump the passengers. However, the men find the diamonds have already been stolen by someone else (Drake). 
Drake is a sort of modern-day Robin Hood. He donates the proceeds of his latest robbery to fund the stalled construction of the "New Social Institute". He even writes a book, "Crackerjack": The true story of my exploits., which becomes a bestseller. Everybody is reading it, including the people at Scotland Yard and Baroness Von Haltz, and wondering if it is fact or fiction. The baroness tells her maid Annie that certain passages somehow remind her of Drake, who broke her heart. 
By coincidence, she is residing in the same hotel as Drake. He goes to see her, but she does not forgive him for leaving her without a word in Berlin. He explains that he was forced to leave suddenly, but she is not mollified.
Meanwhile, Drake instructs Burdge, his secretary, to send a cheque for £10,000 to the Buckingham Hospital for a new wing, even though Burdge informs him he is overdrawn at the bank. Drake tells him that the wealthy Mrs. Humbold's pearls will provide ample funds. The Humbolds are hosting a masquerade ball that night, and the baroness will be there.
At the ball, part of the entertainment is a group called the "Four Gangsters", who have been tied up and replaced by a gang of real gangsters, the same thieves from the aeroplane caper. Sculpie, their leader, kills an unarmed man who foolishly tries to resist. Afterward, however, Sculpie is furious to learn that the pearls he took from Mrs. Humbold are fakes. Once again, Drake has the real ones.

Ex Output:

Passage: Although no new fighting techniques were introduced during the Texas Revolution, casualty figures were quite unusual for the time.  Generally in 19th-century warfare, the number of wounded outnumbered those killed by a factor of two or three.  From October 1835 through April 1836, approximately 1,000 Mexican and 700 Texian soldiers died, while the wounded numbered 500 Mexican and 100 Texian.  The deviation from the norm was due to Santa Anna's decision to label Texian rebels as traitors and to the Texian desire for revenge.During the revolution, Texian soldiers gained a reputation for courage and militance.   Lack points out that fewer than five percent of the Texian population enrolled in the army during the war, a fairly low rate of participation.  Texian soldiers recognized that the Mexican cavalry was far superior to their own.  Over the next decade, the Texas Rangers borrowed Mexican cavalry tactics and adopted the Spanish saddle and spurs, the riata, and the bandana.The Texas Veterans Association, composed solely of revolutionary veterans living in Texas, was active from 1873 through 1901 and played a key role in convincing the legislature to create a monument to honor the San Jacinto veterans.  In the late 19th century, the Texas Legislature purchased the San Jacinto battlesite, which is now home to the San Jacinto Monument, the tallest stone column monument in the world.  In the early 20th century, the Texas Legislature purchased the Alamo Mission, now an official state shrine. In front of the church, in the center of Alamo Plaza, stands a cenotaph designed by Pompeo Coppini which commemorates the defenders who died during the battle. More than 2.5 million people visit the Alamo every year.The Texas Revolution has been the subject of poetry and of many books, plays and films. Most English-language treatments reflect the perspectives of the Anglos and are centered primarily on the battle of the Alamo.  From the first novel depicting events of the revolution, 1838's Mexico versus Texas, through the mid-20th century, most works contained  themes of anticlericalism and racism, depicting the battle as a fight for freedom between good (Anglo Texian) and evil (Mexican). In both English- and Spanish-language literature, the Alamo is often compared to the battle of Thermopylae.  The 1950s Disney miniseries Davy Crockett, which was largely based on myth, created a worldwide craze for everything Alamo-related. Within several years, John Wayne directed and starred in one of the best-known and perhaps least historically accurate film versions, The Alamo (1960).  Notably, this version made the first attempt to leave behind racial stereotypes; it was still banned in Mexico.  In the late 1970s, works about the Alamo began to explore Tejano perspectives, which had been all but extinguished even from textbooks about the revolution, and to explore the revolution's links to slavery.

Passage: After Quiriguá's pivotal victory over Copán in 738, K'ak' Tiliw Chan Yopaat rebuilt the main group in the image of Copán itself. Thus, the acropolis, palace, and ballcourt all lie at the southern end of the Great Plaza. The ceremonial centre is laid out around three plazas, the northernmost is the Great Plaza. This plaza measures 325 m (1,066 ft) from north to south and is the largest plaza in the whole Maya region. At the southern end of the Great Plaza is the Ballcourt Plaza, surrounded on three sides by structures associated with the acropolis. The Acropolis Plaza is a fully enclosed plaza within the acropolis itself. The area to the west of the Ballcourt Plaza was probably the riverside docking area and there is evidence that the southern part of the Great Plaza was a marketplace. A number of ceramic-lined wells have been excavated close to the site core, these were all built in the 8th century and although some continued in use into the 9th century, none are known to have been built that late.
1A-1 is an enormous platform forming the northern part of the Great Plaza. It measures 100 by 85 metres (328 by 279 ft) and rises 0.5 metres (20 in) above the level of the southern part of the plaza. It forms the northern portion of the Great Plaza, being built by K'ak' Tiliw Chan Yopaat when he extended the plaza northward. The platform was built from river cobbles and was paved with stone slabs. Platform 1A-1 supported the stelae A, C, D, E and F and Zoomorph B. The platform was built in two phases over about 20 years.
1A-3 is a large mound marking the northern edge of the Great Plaza. It originally measured 82.5 by 20 metres (271 by 66 ft) and was 7 metres (23 ft) high. A 63-metre (207 ft) wide stairway climbed the southern face of the structure from the plaza. The structure was later extended to the north but this second phase of construction was never finished.
The acropolis is the largest architectural complex at Quiriguá, it lies at the southern limit of the ceremonial centre of the city. It is a complex construction, with new buildings and features being added over time. Construction of the acropolis began in 550 and continued through to 810 when the site was abandoned. The acropolis was a palace complex used primarily as an elite residence and for administrative purposes. The acropolis complex includes structures 1B-1, 1B-2, 1B-3, 1B-4, 1B-5 and 1B-6. Excavations of the acropolis encountered the fallen remains of corbel arches, but none are still standing.
