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.

Input: Consider Input: Question: Is the bridge that was slated to begin reconstruction in 2014 complete? Passage:SR 162 was codified as SSH 5E during the creation of the primary and secondary state highways in 1937, beginning at Primary State Highway 5 (PSH 5) and U.S. Route 410 in Puyallup, traveling through Orting and South Prairie to end at an intersection with a branch of PSH 5 southwest of Buckley. SSH 5E had a branch that traveled south from Orting to Electron that was removed from the state highway system in 1955. The highway traveled across the Puyallup River into Orting on the McMillin Bridge, which opened in 1934 as a concrete half-through truss bridge to save the Department of Highways a total of $826. SR 165 was established during the 1964 highway renumbering and was codified in 1970 as the replacement to SSH 5E. The western terminus, now at SR 410, was moved east to an interchange in Sumner after the completion of the Sumner Freeway in 1972. The McMillin Bridge was added to the National Register of Historic Places in 1982 as an example of a half-through truss bridge built with concrete instead of steel. The route of the highway has not seen a major revision since 1972; however, WSDOT repaved the roadway and added guardrails between Orting and Buckley in 2008. The deteriorating McMillin Bridge is being replaced by WSDOT with a newer, wider span over the Puyallup River scheduled to begin construction in 2014.

Input: Consider Input: Question: Is the political party that held a Second Congress in Brussels still active? Passage:Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.

Input: Consider Input: Question: What is the differnce in mass of the two planets that Kepler claimed to have had an epiphany after demonstrating their periodic conjunction in the zodiac? Passage:Kepler's first major astronomical work, Mysterium Cosmographicum (The Cosmographic Mystery, 1596), was the first published defense of the Copernican system. Kepler claimed to have had an epiphany on July 19, 1595, while teaching in Graz, demonstrating the periodic conjunction of Saturn and Jupiter in the zodiac: he realized that regular polygons bound one inscribed and one circumscribed circle at definite ratios, which, he reasoned, might be the geometrical basis of the universe. After failing to find a unique arrangement of polygons that fit known astronomical observations (even with extra planets added to the system), Kepler began experimenting with 3-dimensional polyhedra. He found that each of the five Platonic solids could be inscribed and circumscribed by spherical orbs; nesting these solids, each encased in a sphere, within one another would produce six layers, corresponding to the six known planets—Mercury, Venus, Earth, Mars, Jupiter, and Saturn. By ordering the solids selectively—octahedron, icosahedron, dodecahedron, tetrahedron, cube—Kepler found that the spheres could be placed at intervals corresponding to the relative sizes of each planet's path, assuming the planets circle the Sun. Kepler also found a formula relating the size of each planet's orb to the length of its orbital period: from inner to outer planets, the ratio of increase in orbital period is twice the difference in orb radius. However, Kepler later rejected this formula, because it was not precise enough.
