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: How deep were their heavy infantry formations normally? Passage:Having recovered from their losses at Trebia (218 BC) and Lake Trasimene (217 BC), the Romans decided to engage Hannibal at Cannae, with approximately 86,000 Roman and allied troops. They massed their heavy infantry in a deeper formation than usual, while Hannibal used the double envelopment tactic and surrounded his enemy, trapping the majority of the Roman army, who were then slaughtered. The loss of life on the Roman side was one of the most lethal single day's fighting in history; Adrian Goldsworthy equates the death toll at Cannae to "the massed slaughter of the British Army on the first day of the Somme offensive in 1916." Only about 15,000 Romans, most of whom were from the garrisons of the camps and had not taken part in the battle, escaped death. Following the defeat, Capua and several other Italian city-states defected from the Roman Republic to Carthage.

Example Input: Question: How old is the person Smith got into an altercation with as a teenager? Passage:Smith was born and raised in Brooklyn, New York. He became a wrestling fan in the late 1950s. A childhood friend claimed that they were the first wrestling fans to bring signs to local World Wide Wrestling Federation house shows. Around 1971, Smith also co-founded an unofficial fan club for Freddie Blassie with members wearing homemade "Blassie's Army" T-shirts. As a teenager, Smith had an altercation with Kevin Sullivan while attending a live event at Sunnyside Gardens. Sullivan had been hit with an unknown object at the end of his bout against Davey O'Hannon. Smith, who often cheered for the "heel" wrestlers, had been heckling Sullivan (then a "babyface") throughout the night causing the wrestler to believe that Smith was responsible. The young wrestling fan was brought to the dressing room by building security after the match where he was confronted by Sullivan, Gorilla Monsoon and Arnold Skaaland. Smith denied any wrongdoing and was allowed to leave. Smith continued watching wrestling after moving to Knoxville, Tennessee in the mid-1970s. He eventually met Norvell Austin at a Southeastern Championship Wrestling. Austin later introduced Smith to Rick Conner who agreed to train him.

Example Input: Question: Were the two scientists who conducted survey that confirm the length of a metre both born in France? Passage:Bouguer, La Condamine, Godin and their colleagues measured arcs of the Earth's curvature on the Equator from the plains near Quito to the southern city of Cuenca. These measurements enabled the first accurate determination of the shape of the Earth, eventually leading to the establishment of the international metric system of measurement. When an International Commission for Weights and Measures was convened in Paris to settle the true length of the metre, it adopted on 22 June 1799 a standard metre based on the length of the half meridian connecting the North pole with the Equator. The French Academy of Sciences had commissioned an expedition led by Jean Baptiste Joseph Delambre and Pierre Méchain, lasting from 1792 to 1799, which attempted to accurately measure the distance between a belfry in Dunkerque and Montjuïc castle in Barcelona at the longitude of Paris Panthéon. This portion of the Paris meridian was to serve as the basis for the length of the half meridian connecting the North Pole with the Equator. The metre was defined as the ten-millionth of the half meridian's length extrapolated from a Earth's flattening of 1/334 obtained from the results of the survey by Delambre and Méchain combined with those of the Peru meridian arc as established by La Condamine and his colleagues.
