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.

Q: Question: Did the war that Hurst served in last longer than 2 years? Passage:Aurthur Frederick Hertz was born in Bradford to Fanny Mary and William Martin Hertz, a merchant of German Jewish descent. Hertz changed the spelling of his surname to Hurst in 1916. He attended Bradford Grammar School and Manchester Grammar School before graduating from Magdalene College, Oxford in 1904. He joined the staff of Guy's Hospital in 1906 and ran his own private practice before serving in World War I as a consulting physician stationed in Salonika. From 1916 to 1918, Hurst led the neurology department at Netley Hospital. Seale-Hayne College was repurposed as a military hospital that same year. Hurst moved there to help with treatment of shell shock, working at Netley until 1919. After the war, Hurst relocated his private practice to Windsor and retired in 1939. Upon his retirement, Hurst became a consulting physician and served on Guy's Hospital board of governors. Hurst was knighted in 1937 six years after his older brother Gerald Berkeley Hurst. He died in Birmingham in 1944, aged 65.

Q: Question: What is the population difference between the place where Atkinson visited his parents in 1975 and the place where he found a job with The Morning Sun Newspaper? Passage:While visiting his parents for Christmas at Fort Riley, Kansas, in 1975, Atkinson found a job as a newspaper reporter for The Morning Sun in Pittsburg, Kansas, covering crime, local government, and other topics in southeast Kansas, an area known as “the Little Balkans” for its ethnic diversity and fractious politics. In April 1977, he joined the staff of The Kansas City Times, working nights in suburban Johnson County, Kansas, before moving to the city desk and eventually serving as a national reporter; in 1981, he joined the newspaper's bureau in Washington, D.C. He won the Pulitzer Prize for national reporting in 1982 for a "body of work" that included a series about the West Point class of 1966, which lost more men in Vietnam than any other Military Academy class. He also contributed to the newspaper's coverage of the Hyatt Regency walkway collapse in Kansas City, Missouri, for which the paper's staff in 1982 was awarded a Pulitzer Prize for local spot news reporting.

Q: Question: Where was Charles Fritts living when he invented the first solar cell? Passage:A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide, although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost US$286/watt and reached efficiencies of 4.5–6%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
