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: Who won the Austrian Grand Prix in which Leclerc finished second? Passage:In China, Leclerc qualified 4th behind Vettel. After overtaking his teammate during the start, he was asked to yield and let Vettel pass. He eventually finished the Chinese Grand Prix in 5th. In Azerbaijan, he was the favourite for pole position until a crash in the second qualifying session ended his contention. He started 8th after penalties for the two Alfa Romeos and finished the race 5th with an extra point for the fastest lap of the race. At the following race in Monaco, he qualified 16th, as part of Ferrari's erroneous strategy that kept him in the garage to save tyres, underestimating track evolution at the end of the qualifying session. He was however promoted to 15th following Antonio Giovinazzi's grid penalty. He overtook Lando Norris and Romain Grosjean but suffered a puncture after a failed attempt to pass the Renault of Nico Hülkenberg. He also suffered severe floor damage to his car, leading to his second retirement at his home race. Leclerc qualified 3rd in Canada, ahead of Daniel Ricciardo in the Renault and behind Lewis Hamilton in the Mercedes. He would finish in the same position, his second podium finish of the season and of his career, behind the controversial 1-2 finish of Hamilton and teammate Sebastian Vettel. He would finish third again in France, having caught up to second-placed Bottas in the closing laps. At the Austrian Grand Prix, he qualified on pole position, the second pole of his Formula 1 career. He subsequently finished second after colliding with Red Bull's Max Verstappen, having led for the major part of the race. The incident was investigated by the stewards after the race, who called it 'a racing incident' and decided against taking action as neither of them was, wholly or predominantly, to blame for the incident.

Example Input: Question: How big is the National Park that the Yellowstone River flows northward through? Passage:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.

Example Input: Question: Which of Wolfgang's other Disney shorts had the longest air time? Passage:Reitherman was hired at Walt Disney Productions on May 21, 1933, and his first project was working as an animator on the Silly Symphonies cartoon, Funny Little Bunnies. Reitherman continued to work on a number of Disney shorts, including The Band Concert, Music Land, and Elmer Elephant. He animated the Slave in the Magic Mirror in Snow White and the Seven Dwarfs (1937). His next assignments was animating Monstro in Pinocchio (1940), the climactic dinosaur fight in Igor Stravinsky's The Rite of Spring in Fantasia (1940), and several scenes of Timothy Q. Mouse in Dumbo (1941). Starting in 1942, Reitherman had left Disney to serve in World War II for the United States Air Force, earning the Distinguished Flying Cross after serving in Africa, China, India and the South Pacific. He was discharged in February 1946 having earned the rank of Major. Reitherman rejoined Disney in April 1947, where he animated the Headless Horseman chase in "The Legend of Sleepy Hollow" section in The Adventures of Ichabod and Mr. Toad (1949). Around this same time, he had claimed he was instrumental in helping Walt Disney commit to producing Cinderella (1950). Reitherman recalled, "I just went in his office which I rarely did, and I said, 'Gee, that looks great. We ought to do do it.' It might have been a little nudge to say, 'Hey, let's get going again and let's do a feature'." On Cinderella, he was the directing animator of the sequence in which Jaq and Gus laboriously push and pull the key up the stairs to Cinderella. On Alice in Wonderland (1951), he animated the scene in which the White Rabbit's home is destroyed by an enlarged Alice. On Peter Pan (1953), he animated the scene of Captain Hook attempting to escape the crocodile. For Lady and the Tramp (1955), Reitherman animated the alley dog fight sequence and Tramp's fight with the rat in the nursery room.
