In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: How many species of the Aru Flying fox are there? Passage:Of the 62 flying fox species evaluated by the IUCN as of 2018, 3 are considered critically endangered: the Aru flying fox, Livingstone's fruit bat, and the Vanikoro flying fox. Another 7 species are listed as endangered; 20 are listed as vulnerable, 6 as near threatened, 14 as least concern, and 8 as data deficient. A further 4 are listed as extinct: the dusky flying fox, the large Palau flying fox, the small Mauritian flying fox, and the Guam flying fox. Over half of the species are threatened today with extinction, and in particular in the Pacific, a number of species have died out as a result of hunting, deforestation, and predation by invasive species. Six flying fox species are believed to have gone extinct from 1864 to 2014: the Guam, large Palau, small Mauritian, dusky, large Samoan, and the small Samoan flying foxes.

Example Input: Question: Did Tyler Sheehan attend high school and college in the same state? Passage:Tyler Allen Sheehan is a former American football quarterback. Sheehan played collegiately at Bowling Green State University after a standout career at La Salle High School in Cincinnati, Ohio. After going undrafted in the 2010 NFL Draft, he signed with Houston Texans, where he was released after training camp. In 2011, he signed with the Cincinnati Commandos of the Continental Indoor Football League. Sheehan led the Commandos to a perfect 10-0 regular season, winning the league's MVP award. In the playoffs, Sheehan led the Commandos to the 2011 CIFL Championship Game, where they defeated the Marion Blue Racers 44-29. After the Commandos season ended, Sheehan signed with the Arizona Rattlers of the Arena Football League, but never appeared in a game. In 2012, Sheehan returned to the Commandos and led them to a 7-2 record, this time in the United Indoor Football League. The Commandos took the first place seed into the playoffs, and won Ultimate Bowl II 62-44 over the Florida Tarpons.

Example Input: Question: Where does Badd Company's reign as AWA World Tag Team Champions rank all-time? Passage:The team's first feud was against The Midnight Rockers, whom they defeated for the AWA World Tag Team Championship on March 19, 1988. During their year long title reign, Badd Company would feud heavily with Chavo and Mando Guerrero and the team known as the Top Guns (Ricky Rice and Derrick Dukes). They teamed with Madusa Miceli to face the team of the Top Guns and Wendi Richter at the first AWA PPV, SuperClash III. Both Badd Company's Tag Team Title and Wendi Richter's AWA World Women's Championship were on the line, but since Richter pinned Miceli, Badd Company remained the champions. Diamond and Tanaka's reign ended on March 25, 1989 as they lost to "the Olympians" (Brad Rheingans and Ken Patera). Shortly after losing their titles they split from Page, and had a short feud against each other before wrestling in singles competition until early 1990. Just before moving to the WWF, Diamond teamed with The Trooper Del Wilkes for a short run at the AWA Tag Team Titles against The Destruction Crew (Mike Enos and Wayne Bloom). Diamond and Trooper actually defeated The Destruction Crew, but were not awarded the titles when it was determined that Diamond pinned the wrong person.
