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: What is the length of Interstate 380? Passage:On March 18, 1965, a 33-year-old truck driver, Eugene P. Sesky, was on his way to deliver a load of bananas to Scranton, Pennsylvania. Sesky, an employee of Fred Carpentier—operator of a small truck line in Scranton—was returning from the boat piers at Weehawken, New Jersey, where he had picked up his load. The load was destined for the locations in the "wholesale block" on the western edge of Lackawanna Avenue in Scranton—either the local A&P Warehouse or to Halem Hazzouri Bananas, the premier banana seller in the area at the time. Sesky was driving a 1950s Brockway diesel truck tractor with a semi-trailer and was headed down Rt. 307 when he suddenly lost control. That section of Rt. 307 contains a two-mile descent extending from Lake Scranton to the bottom of Moosic Street that includes a drop in elevation of more than in less than . Sesky was unable to control the truck's speed down the hill due to a mechanical failure, variously attributed to the truck's brake system or its clutch. As a result, the truck cruised into Scranton at approximately , sideswiping a number of cars before it crashed into a house at the southwest corner of Moosic St and S. Irving Ave (), close to the bottom of the hill. Witnesses reported that Sesky did everything possible to avoid pedestrians and other motorists, including climbing out onto the truck's running board to try to warn people, and some have suggested that he may have deliberately flipped the truck over to avoid striking either bystanders or an automotive service station on Moosic Street that could have exploded in flames, causing a greater loss of life. Sesky was thrown from the truck and killed and bananas were spilled and strewn when the rig came to rest; 15 others were injured but only Sesky died. The road was closed for cleanup as Johnson's Towing Company helped out in the recovery. Trucks over 21,000 lb (10.5 t) are no longer allowed to travel that route (they must use Interstate 380 via Dunmore.)

Example Input: Question: On what album was the Gerry Rafferty song from that is referenced in the show? Passage:While telling Bart and Lisa about 1990, Homer says, "Tracey Ullman was entertaining America with [...] crudely drawn filler material." This is a reference to The Simpsonss debut as "bumpers" airing before and after commercials on The Tracey Ullman Show. The song "Those Were the Days" parodies the opening credits of the television show All in the Family. One of the people who run over the saxophone is a man on a tricycle, who promptly falls over. This is a reference to the show Rowan & Martin's Laugh-In. At the beginning of the flashback, the song "Don't Worry, Be Happy" by Bobby McFerrin can be heard. In the flashback, Dr. Hibbert fashioned his hair and attire like Mr. T in The A-Team. Homer can be seen watching Twin Peaks and The Giant is then shown waltzing with the White Horse. In King Toot's music store, when Homer buys Lisa her first saxophone, there is a guitar in the background that is similar to Eddie Van Halen's "Frankenstrat" guitar. The photo beside Kent Brockman on the news has him modeled after the Coppertone Girl. At the end of the episode, Lisa performs a brief, cruder rendition of the hook of "Baker Street" by Gerry Rafferty on her new saxophone before the music segues into the original song.

Example Input: Question: Who is the current mayor of the town that was near  the spot where the Baldwin collided with Ellen Spry? Passage:In March of 1873 the Baldwin had a second deck added in Chicago, Illinois, this increased her gross tonnage to 634 tons, and is believed to have made her the first double decked steamer on the lakes. On April 30, 1876 she went ashore at North Point Reef on Lake Huron. On June 18, 1876 the Baldwin collided with the schooner Ellen Spry off Kewaunee, Wisconsin. At an unknown date in 1877, she went ashore near Alpena, Michigan, and was repaired afterwards in Detroit, Michigan. In 1879 the Baldwin was sold to the Inter Ocean Transportation Company of Milwaukee, Wisconsin. In April, 1882 she was sold to David Whitney Jr. of Detroit, Michigan, and her second deck was removed in order to refit her for the lumber trade. after the refit, the Baldwin gross tonnage was reevaluated to 412.5 tons. In 1884 it was reported that she was damaged near Ashland, Wisconsin. Following engine failure, and a storm near Port Colborne, Ontario. she was rebuilt with steel arches, and her original engine was replaced with a 450-horsepower Steeple compound engine that had a cylinder with a 37 x 32 inch bore and a stroke measuring 21 inches. On September, 1886 the Baldwin went aground in Lake George in the St. Marys River with the freighter R.J. Hackett; both of them were released by the tug Mystic. In 1891 she was sold to the Whitney Transportation Company of Hamtramck, Michigan. In 1892 the Baldwin was sold to S.R. MacLaren of Toledo, Ohio. On November 5, 1894 the Baldwin collided with the steamer Iron King off Marine City, Michigan, and sank in of water.
