In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: How many world championships have been won by the team that the Reds outscored 22-8? Passage:On the mound, the Reds relied on left-handers Don Gullett and Fred Norman to pacify the Yankee hitters in Games 1 and 2, respectively. Gullett had come back from a mid-season injury to start Game 1 but had to leave the game in the eighth inning due to a twisted ankle while Norman out-pitched ace Hunter in Game 2. Game 3 in New York pitted effective 1976 NL Rookie of the Year Pat Zachry for the Reds against newly acquired Yankee, Dock Ellis. Ellis only lasted innings, exiting in the fourth after a home run by Driessen. Game 4 was delayed a day due to rain, but the Reds were ready for the sweep. Bench's two-run home run gave the Reds a 3–1 lead. In the bottom of the eighth, a frustrated Billy Martin threw a baseball from the dugout onto the field towards home plate umpire Bill Deegan, causing his ejection from the game. In the ninth, Bench's second home run followed by back-to-back doubles by César Gerónimo and Dave Concepción made the score 7–2 and essentially blew the game open. The Cincinnati Reds outscored the New York Yankees, 22–8, and became the first NL team to repeat as World Champions since the 1921–1922 New York Giants. The Reds did not make a single offensive or defensive substitution (save pitching changes) during the entire series. Bench would claim the MVP of the series hitting .533 with two home runs and six runs batted in. His catching counterpart, Thurman Munson, had nine hits, all singles, and a .529 batting average.

Example Input: Question: Who were the crew members on the flight to the moon in 1972? Passage: are three views of Mare Tranquillitatis on the Moon, taken by the mapping camera of the Apollo 17 mission in 1972, facing south-southwest from an average altitude of 111 km on Revolution 36 of the mission. At the left is the east side of Mare Tranquillitatis, with the craters Franz (bottom right), Lyell (dark floor, right of center), and Taruntius (upper left). The "bay" of dark mare (basalt) at left is Sinus Concordiae, with "islands" of older, light highland material. At the right is the crater Cauchy, which lies between the Rupes Cauchy and Cauchy rille. The center photo shows the central mare with craters Vitruvius (lower right) and Gardner (bottom center). At the horizon are lighter highlands at the southern margin of the mare, near the Apollo 11 landing site. The crater Jansen is visible at the edges of both the center and right photos. The right photo shows the western mare, with the craters Dawes (lower left) and the large Plinius (43 km diameter), with the Plinius Rilles in the foreground. These photos were taken within minutes of each other as the command module America orbited the Moon. The Sun elevation drops from 46 degrees at left to 30 degrees at right.

Example Input: Question: Were either of the men that Slater accompanied aboard the  HMS Shearwater born in Scotland? Passage:In 1874 he accompanied the botanist Isaac Bayley Balfour and George Gulliver aboard HMS Shearwater on an expedition to observe the transit of Venus on Rodrigues. In addition to studies of the flora and fauna, Slater excavated the subfossil bones of extinct birds, including the Rodrigues solitaire (Pezophaps solitaria) and Rodrigues starling (Necropsar rodericanus). His records were used by the zoologists Albert Günther and Alfred Newton to write the first scientific description of the Rodrigues starling in 1879. During a stay in Mauritius in 1875 he and George Gulliver explored the flora, the herpetofauna, and the aquatic avifauna. In 1885 he traveled with Thomas Carter to Iceland. Based partly on his work there, he wrote the Manual of the Birds of Iceland, published in 1901. In 1897 Slater described the short-tailed parrotbill (Paradoxornis davidianus) and the sulphur-breasted warbler (Phylloscopus ricketti). Together with William Bernhardt Tegetmeier and Frederick William Frohawk, he wrote the fifth volume of British Birds With Their Nests and Eggs (1898). In 1877 Slater was elected a Fellow of the Zoological Society of London (FZS). He was also a member of the British Ornithologists' Union.
