In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Where was the man born who had an accident on lap 70 of the race? Passage:Ten laps into the race, Michael Waltrip passed pole-sitter Jeff Gordon for the lead. On Lap 19, the caution flag was thrown after a multi-car accident. Waltrip continued leading until Lap 55, in which Dale Earnhardt Incorporated teammate Dale Earnhardt, Jr. After Bobby Hamilton, Jr. had an accident on Lap 70, Earnhardt led the race into pit road, but was pushed out by Gordon and Brian Vickers, and fell to fifteenth, giving Mike Wallace the lead entering Lap 74. Shepherd pitted on the following lap, and Morgan Shepherd took the lead. However, Shepherd would later pit, as Gordon regained the lead. Waltrip then retook the lead from Gordon on Lap 86, though Gordon then took the lead again 13 laps later. Ten laps later, Gordon pitted, and Waltrip was given the lead. On the ensuing lap, Earnhardt took the lead, though he later pitted, and Jimmy Spencer gained the lead. On Lap 113, Spencer lost the lead to Gordon when he pitted, who led the pit stops on Lap 139. Dave Blaney stayed out, and took the lead, though Ryan Newman gained first-place when Blaney went to pit road. Newman pitted on Lap 143, giving Tony Stewart the lead. With ten laps left in the race, Hendrick Motorsports teammates Jeff Gordon and Jimmie Johnson followed in third and fourth, respectively, behind Tony Stewart and Dale Earnhardt, Jr. Johnson then pushed Gordon past Stewart and Earnhardt, and Gordon subsequently won, his fourth of the season and second consecutive. The victory by Gordon made him the first driver since Cale Yarborough to win the Pepsi 400 from the pole. A version of the race's waning moments was included in the prologue of the video game , which involved Johnson pushing Gordon past Earnhardt.

Example Output: b

Example Input: Question: Who won the AFC West in the years that the Raiders went 8-8 under Gruden? Passage:Under Gruden, the Raiders posted consecutive 8–8 seasons in 1998 and 1999, and leapt out of last place in the AFC West. After uniting with journeyman quarterback Rich Gannon, Gruden led the Raiders to the top of the AFC West and they made the playoffs in three consecutive seasons from 2000 to 2002 (the third season was under head coach Bill Callahan). Oakland finished 12–4 in the 2000 season, the team's most successful season in a decade, and its first division title since 1990, ultimately reaching the , where they lost, 16–3, to the eventual Super Bowl champions Baltimore Ravens. In 2001, the Raiders would return to the postseason with a 10–6 record, but in the AFC Divisional Round a negated fumble proved costly as they were defeated, 16–13, in overtime by the eventual Super Bowl champions New England Patriots. While Gruden was with the Raiders, Gruden acquired his nickname "Chucky" from Raiders defensive lineman Grady Jackson, who thought that the coach looked like the fictional character "Chucky" in the 1988 slasher movie Child's Play.

Example Input: Question: Which Dynasty produced the most mathmaticians? Passage:Four outstanding mathematicians arose during the Song Dynasty and Yuan Dynasty, particularly in the twelfth and thirteenth centuries: Yang Hui, Qin Jiushao, Li Zhi (Li Ye), and Zhu Shijie. Yang Hui, Qin Jiushao, Zhu Shijie all used the Horner-Ruffini method six hundred years earlier to solve certain types of simultaneous equations, roots, quadratic, cubic, and quartic equations. Yang Hui was also the first person in history to discover and prove "Pascal's Triangle", along with its binomial proof (although the earliest mention of the Pascal's triangle in China exists before the eleventh century AD). Li Zhi on the other hand, investigated on a form of algebraic geometry based on tiān yuán shù. His book; Ceyuan haijing revolutionized the idea of inscribing a circle into triangles, by turning this geometry problem by algebra instead of the traditional method of using Pythagorean theorem. Guo Shoujing of this era also worked on spherical trigonometry for precise astronomical calculations. At this point of mathematical history, a lot of modern western mathematics were already discovered by Chinese mathematicians. Things grew quiet for a time until the thirteenth century Renaissance of Chinese math. This saw Chinese mathematicians solving equations with methods Europe would not know until the eighteenth century. The high point of this era came with Zhu Shijie's two books Suanxue qimeng and the Siyuan yujian. In one case he reportedly gave a method equivalent to Gauss's pivotal condensation.
