instruction:
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.
question:
Question: What were the combined ages of Joseph Urban and Benjamin Wistar Morris the year that they were both hired to come up with blueprints for the house? Passage:The construction of Rockefeller Center occurred between 1932 and 1940 on land that John D. Rockefeller Jr. leased from Columbia University. The Rockefeller Center site was originally supposed to be occupied by a new opera house for the Metropolitan Opera. By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house. However, the new building was too expensive for the opera to fund by itself, and it needed an endowment, and the project ultimately gained the support of John D. Rockefeller Jr. The planned opera house was canceled in December 1929 due to various issues, with the new opera house eventually being built at Lincoln Center, opening in 1966.

question:
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.

question:
Question: What is the current enrollment of the school where Cissé studied physics?  Passage:Cissé was born in Niamey, Niger. As a child he assumed that he would work in his father's law firm. He became interested in science through Hollywood films. In Niamey there were few opportunities to practise science as his school did not have a laboratory. He was keen to move to America to study, and completed high school two years early. He moved to the United States at the age of 17 to attend college. Cissé studied physics at the North Carolina Central University and graduated in 2004. During his undergraduate degree he was encouraged by Carl Wieman to apply for a fellowship, and spent a summer at Princeton University working in condensed matter physics. During this summer project he looked at jammed disordered packings, investigating how M&M's arrange in a small volume with Paul Chaikin. Cissé used various techniques to study jammed packings, including magnetic resonance imaging, but in the end used a much simpler approach - painting M&M's and analysing how many times they knocked into each other. The result was published in Science. He moved to Urbana for his graduate studies, and earned his PhD under the supervision of single molecule biophysicist Taekjip Ha at the University of Illinois at Urbana–Champaign in 2009. After completing his doctorate, Cissé joined the École Normale Supérieure in Paris. He worked as a Pierre Gilles de Gennes Fellow in the joint labs of a physicist, Maxime Dahan, and a biologist, Xavier Darzacq. He also held a long-term fellowship with the European Molecular Biology Organization. In Paris, Cissé developed the single-cell microscopy technique time-correlated photoactivated localization microscopy (tcPALM), allowing for time resolved measurements in vitro. Cissé used transient-PALM to demonstrated that RNA polymerase II forms clusters that deconstruct after their work is done. Until Cissé made this discovery it was assumed that RNA polymerases were stable.
