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.

Question: How long had Jeffrey Ullman been teaching at Stanford the year Mairson got his B.A.? Passage:Mairson received a B.A. in Mathematics from Yale University in 1978 and a Ph.D. in Computer Science from Stanford University in 1984 under the supervision of Jeffrey Ullman. His Ph.D. thesis, The Program Complexity of Searching a Table, won the Machtey Award at the 1983 IEEE Symposium on Foundations of Computer Science (FOCS). Mairson was a Postdoctoral researcher at INRIA Rocqencourt from 1984 to 1985, at Stanford University in 1985, and at the University of Oxford in 1986. He held a Visiting Professor position from 1999 to 2001 at Boston University. From 2005 to 2007, Mairson has served as the Chair of the Faculty Senate at Brandeis.

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.

Question: What position did Richard Seymour play on the Patriots? Passage:Battling the Dolphins for the division lead, the Patriots erased a 13–6 gap with a Brady touchdown pass to David Givens in the third. The Dolphins marched down field late in the fourth; during this drive a Ricky Williams first down run was protested by the Patriots who felt Williams' knee touched the dirt infield at Pro Player Stadium, but the challenge was denied. The Dolphins attempted a 35-yard field goal at the two-minute warning, but the kick was blocked by Richard Seymour. The Dolphins smothered the Patriots' final drive attempt (the decisive play came when former Patriot Terrell Buckley stopped Kevin Faulk for a four-yard loss and the game went to overtime. Controversy ensued on the coin flip for overtime; referee Gerald Austin used a silver dollar; the coin came up Lady Columbia (which is "heads" on a silver dollar) but Patriot captains Brady and Seymour protested that it came up "tails." The Dolphins drove downfield but missed another 35-yard field goal try, in part because Olindo Mare couldn't plant his foot on the infield dirt, which was still in place because of the Florida Marlins' run towards their 2003 World Series victory; after forcing a Patriots punt Jay Fiedler was hit by Tedy Bruschi and lobbed a 60-yard pass picked off at the Patriots 18-yard line by Tyrone Poole. Brady then ended the game with a spectacular 82-yard touchdown strike to Troy Brown and a 19–13 final.
