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 long was the reign of the pharaoh who  used 11,000 mercenaries during his battles? Passage:An early recorded use of foreign auxiliaries dates back to Ancient Egypt, the thirteenth century BC, when Pharaoh Ramesses II used 11,000 mercenaries during his battles. A long established foreign corps in the Egyptian forces were the Medjay—a generic term given to tribal scouts and light infantry recruited from Nubia serving from the late period of the Old Kingdom through that of the New Kingdom. Other warriors recruited from outside the borders of Egypt included Libyan, Syrian and Canaanite contingents under the New Kingdom and Sherdens from Sardinia who appear in their distinctive horned helmets on wall paintings as body guards for Ramesses II. Celtic mercenaries were greatly employed in the Greek world (leading to the sack of Delphi and the Celtic settlement of Galatia). The Greek rulers of Ptolemaic Egypt, too, used Celtic mercenaries. Carthage was unique for relying primarily on mercenaries to fight its wars, particularly Gaul and Spanish mercenaries.

Example Input: Question: Did Manchester United win the league the season that Humphreys was voted Player of the Year? Passage:At the end of the 2007–08 season, Humphreys was voted Player of the Year, Player of the 2000s and Hartlepool United's Player of the Century. He continued to be a key player in 2008–09, making a total of 54 appearances. He was a key figure once again in the 2009–10 season, missing just nine matches as a central midfielder. On 26 February 2011, Humphreys replaced Joe Gamble after 82 minutes to make his 473rd appearance for "Pools". This broke the record previously held by Watty Moore for over half a century. Over the course of the 2010–11 season he played 29 matches. On 2 August 2011, Humphreys was given a testimonial match against Premier League Sunderland to mark his ten years at Hartlepool United. Sunderland won 3–1, though the 5,757 fans present at the Victoria Park were reported to be very vocal in their appreciation of the veteran player. On 7 January 2012, Humphreys replaced Luke James 90 minutes into a 2–0 win over Rochdale to make his 500th appearance for "Pools". He signed an "undisclosed extension to his contract" in May 2012. He made 33 appearances in the 2012–13 campaign, as Hartlepool were relegated into League Two, though Humphreys was named on the League One team of the week after scoring in a 3–2 win at Sheffield United on 29 December.

Example Input: Question: How many years were there between the opening of Lawrence Livermore National Laboratory and the creation of metallic hydrogen by a group of scientists at the lab? Passage:In March 1996, a group of scientists at Lawrence Livermore National Laboratory reported that they had serendipitously produced the first identifiably metallic hydrogen for about a microsecond at temperatures of thousands of kelvins, pressures of over , and densities of approximately . The team did not expect to produce metallic hydrogen, as it was not using solid hydrogen, thought to be necessary, and was working at temperatures above those specified by metallization theory. Previous studies in which solid hydrogen was compressed inside diamond anvils to pressures of up to , did not confirm detectable metallization. The team had sought simply to measure the less extreme electrical conductivity changes they expected. The researchers used a 1960s-era light-gas gun, originally employed in guided missile studies, to shoot an impactor plate into a sealed container containing a half-millimeter thick sample of liquid hydrogen. The liquid hydrogen was in contact with wires leading to a device measuring electrical resistance. The scientists found that, as pressure rose to , the electronic energy band gap, a measure of electrical resistance, fell to almost zero. The band-gap of hydrogen in its uncompressed state is about , making it an insulator but, as the pressure increases significantly, the band-gap gradually fell to . Because the thermal energy of the fluid (the temperature became about due to compression of the sample) was above , the hydrogen might be considered metallic.
