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 was the New York giants regular season record the year Wally Pipp hit .296, and the Yankees lost to them that same year in the World Series? Passage:In 1918, Pipp hit only two home runs, but batted .304. He missed playing time under the nation's "work or fight" rule during World War I; he worked as a naval aviation cadet at the Massachusetts Institute of Technology. He batted .275 with seven home runs in 1919, as Babe Ruth surpassed him as the best power hitter in the American League. The Yankees moved to strengthen their team after the 1919 season, adding Ruth and fellow outfielder Bob Meusel and third baseman Joe Dugan. Between 1920 and 1924, Pipp had a .301 average, with season averages of 29 doubles, 94 runs scored, and 97 runs batted in (RBI) per season. Led by their strong lineup and additions to the pitching staff, such as Waite Hoyt, the Yankees finished in second place in 1920. Pipp became the cleanup hitter, behind Ruth in the batting order. Pipp hit .296 in 1921, and the Yankees won the American League pennant. However, they lost the 1921 World Series to the crosstown rival New York Giants of the National League.

Example Input: Question: How many terms as a senator did  Robert Kean's father serve? Passage:Kean was born September 28, 1893, in Elberon, New Jersey. His father, Hamilton Fish Kean (1862–1941), was a United States Senator from New Jersey and his son, Thomas Kean, served two terms as the Governor of New Jersey. Robert Kean was the great-great-grandson of John Kean, a Delegate to the Continental Congress from South Carolina (1756–1795). His uncle, John Kean (1852–1914), was also a United States Senator from New Jersey. His grandson, Thomas Kean, Jr., is presently the Minority Leader of the New Jersey State Senate. His mother, Katherine Taylor Winthrop (1866–1943), was a descendant of John Winthrop, a wealthy English Puritan lawyer and one of the leading figures in the founding of the Massachusetts Bay Colony, the first major settlement in what is now New England after Plymouth Colony.

Example Input: Question: How old was Portnoy when he began playing drums from Dream Theater? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.
