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: In which state did Don Cardwell no-hit the St. Louis Cardinals 4-0 in the second game of a doubleheader? Passage:Cardwell was traded to the Cubs on May 13, 1960, for Tony Taylor. Two days later, he no-hit the St. Louis Cardinals 4–0 in the second game of a doubleheader at Wrigley Field—the first no-hitter ever thrown by a pitcher in his first start with a new team. The lone baserunner for the Cardinals was by a walk from Cardwell to Alex Grammas with one out in the first inning; Cardwell then retired the next 26 batters. Two ninth-inning catches enabled Cardwell to secure the no-hitter: the first catch by Cubs right fielder George Altman on a Carl Sawatski line drive for the first out of the inning, and the second catch by Cubs left fielder Walt "Moose" Moryn on Joe Cunningham's sinking line drive to end the game, Moryn catching the ball just inches off the ground. Cardwell finished the season 9–16 and the Cubs 60–94 despite his no-hitter. Cardwell also showed his hitting ability in 1960, getting 16 hits including five home runs in 77 at bats for a .208 batting average.

Example Input: Question: How large is the lake that the trail passes south of? Passage:Reports from the fur trappers who first entered the mountains and those following mention the trail through the pass as being in long term us by the Shoshone, Bannack, Arapaho, Gros Ventre, Flat Head or Bitterroot Salish, Nez Perce, Crow and others. The pass provide access into three river sheds. An east-west route ran from the east up the Wind River valley and provided a western route by the Gros Ventre or Hoback Rivers to the Valley of the Snake River in Jackson's Hole. To go south, the traveler would follow the Green River. The Union Pass Route was an extension of a North South Route up the Valley of the Yellowstone. Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone. Crossing over Two Ocean Pass, the trail split east and west around Terrace Mountain into the Wind River Valley at DuNoir. From Union Pass south bound travelers could use the Green River Valley to connect east through South Pass or west toward the Snake River.

Example Input: Question: What part of England was the area that produced fustian located in? Passage:In the 18th century, England was famous for its woollen and worsted cloth. That industry, centred in the east and south in towns such as Norwich, jealously protected their product. Cotton processing was tiny: in 1701 only of cottonwool was imported into England, and by 1730 this had fallen to . This was due to commercial legislation to protect the woollen industry. Cheap calico prints, imported by the East India Company from Hindustān (India), had become popular. In 1700 an Act of Parliament passed to prevent the importation of dyed or printed calicoes from India, China or Persia. This caused demand to switch to imported grey cloth instead—calico that had not been finished—dyed or printed. These were printed with popular patterns in southern England. Also, Lancashire businessmen produced grey cloth with linen warp and cotton weft, known as fustian, which they sent to London for finishing. Cottonwool imports recovered though, and by 1720 were almost back to their 1701 levels. Again the woollen manufacturers, in true protectionist fashion, claimed that the imports were taking jobs away from workers in Coventry. The Woollen, etc., Manufactures Act 1720 was passed, enacting fines against anyone caught wearing printed or stained calico muslins. Neckcloths and fustians were exempted. The Lancashire manufacturers exploited this exemption; coloured cotton weft with linen warp were specifically permitted by the 1736 Manchester Act. There now was an artificial demand for woven cloth.
