In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

[EX Q]: Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
Answer: 310
[EX A]: How many species of pigeons are there?

[EX Q]: Passage: The 1966 NASCAR season opened at Augusta Speedway on November 14, 1965, with Richard Petty winning the season opening event in a 1965 Plymouth. NASCAR then ventured to Riverside International Raceway where Dan Gurney took the checkered flag in a 1965 Ford. After the January 23rd Riverside event, the drivers and teams traveled to Daytona International Speedway in Florida for the 1966 Daytona 500. Paul Goldsmith and Early Balmer took the qualifying events, while Richard Petty notched his first and only Daytona 500 pole position. Petty came from two laps down during the competition to win by more than a full lap when the race was halted 2 laps shy of scheduled event due to thunderstorms. In March Paul Goldsmith won at Rockingham Speedway, Dick Hutcherson at Bristol, and Jim Hurtubise captured the checkered flag at Atlanta Motor Speedway. Hutcherson's victory at Bristol was by more than 4 laps over the closest competitor, Paul Lewis, when crashes and attrition left only seven cars of the 38 starters running at the end of the Southeastern 500 (now known as Food City 500). On April 3, Pearson finally found his way to victory lane in the first of four consecutive victories at Hickory Motor Speedway. He followed up with wins at Columbia Speedway, Greenville, and Winston-Salem, before Jim Paschal broke his streak at North Wilksboro and repeated at Martinsville Speedway. On May 7, Richard Petty started a string of three consecutive wins at Darlington Raceway, Hampton, and Macon. After Ford's announcement of their boycott of NASCAR on April 7, only 2.500 fans attend the May 13th event in which Darel Dieringer captures the win at Monroe in a contest.

[EX Q]: Passage: In 1889 de Mores joined La Ligue antisemitique de France (Antisemitic League of France) founded by Edouard Drumont. After more verbal attacks on Jews, he went to Algeria to strengthen the French hold there and stop British advances into the interior of Africa. He used anti-Semitic rhetoric to his advantage in Algeria, giving speeches claiming that French and African Jews and the British were conspiring to conquer the entire Sahara Desert. With the British in a difficult position in the Sudan after the death of General Charles George Gordon in the siege of Khartoum, de Mores planned a trip there to meet with the Mahdi, a powerful Muslim leader who was intent on undermining British hegemony in the region. He traveled to North Africa, selected Arabic men in Tunis to escort him, and set out his caravan towards Kebili.
Link Information: The failure to rescue General Gordon's force in Sudan was a major blow to Prime Minister Gladstone's popularity. Queen Victoria sent him a telegram of rebuke which found its way into the press. Victoria's telegram was not coded as usual which suggests she wanted it to appear in the press. Critics said Gladstone had neglected military affairs and had not acted promptly enough to save the besieged Gordon. Critics inverted his acronym, "G.O.M." (for "Grand Old Man"), to "M.O.G." (for "Murderer of Gordon"). Answer: Prime Minister Gladstone
[EX A]:
Who was held responsible for Charles George Gordon's death?
