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.

[EX Q]: Question: What age was Pastornicky's replacement in 2012? Passage:Following the conclusion of the 2011 season, Braves general manager Frank Wren highlighted several important areas to improve during the offseason. Since most players were committed contractually to the team in 2012, Wren acknowledged that he would likely make few major changes. One spot that was mentioned for a major overhaul was the shortstop position, where Alex González had played since the Yunel Escobar trade with Toronto in July 2010. González entered the offseason as a free agent and proved too expensive for the team. Wren ultimately allowed prospect Tyler Pastornicky the starting duties in 2012, until he was replaced by Andrelton Simmons in mid-June. When Simmons was hurt in July, Jack Wilson, Paul Janish, and Martín Prado filled in for him. While center fielder Michael Bourn returned to his position in 2012, Wren also suggested that the corner outfield positions were areas of contention. In 2011, the Atlanta outfielders finished the season last in the National League in on-base plus slugging and slugging percentage. Wren stated that right fielder Jason Heyward and left fielder Martín Prado had no guarantee of getting the starting jobs in 2012. On the day after the Braves were eliminated from the playoffs in 2011, Wren said that veteran starter Derek Lowe was unlikely to have a spot in the starting rotation in 2012, due his poor performance in 2011 and a plethora of rookie pitching talent in the Braves farm system. With Lowe guaranteed $15 million in 2012, Wren projected that any of Lowe's salary picked up by another team would significantly assist his efforts to find a shortstop or outfielder. By the end of October, Lowe was traded to the Indians.

[EX Q]: Question: Were Caton and Beck both from Poland? Passage:From the bioelectricity of nerves, Marxow turned his attention, from 1876 on, to the global electrical activity of the cerebral hemispheres. Neuroanatomists had already determined at the time that its nervous tissue was also composed of cells (the neurons), with their bodies mainly located in the gray matter, and filamentary prolongations, the dendrites and the axons. Thus, it was only natural to assume that they would also display electrical activity. This important discovery, however, had not been made until that time, because many desynchronized electrical potentials with different polarities produce a cumulative global potential which is actually very small and difficult to detect with the sensitivity range of the measuring devices available at the time. Despite this, Marxow was able to prove for the first time that the peripheral stimulation of sensory organs, such as vision and hearing were able to provoke event-related small electrical potential swings on the surface of the cerebral cortex which was related to the projection of those senses. Strangely, however, Marxow did not publish his results, choosing instead to deposit them in a bank safe, with instructions to reveal them in 1883 only. Meanwhile, the first publications about what was later to be called the electroencephalogram came to light, independently demonstrated by Richard Caton (1842–1926), in Great Britain, and Adolf Beck (1863–1942) in Poland, both using laboratory animals.

[EX Q]: Question: Who was the winner of the Super Bowl when Reeves performed at the halftime show? Passage:Having moved to Los Angeles, Reeves took acting classes at the Lee Strasberg Institute, and appeared in the movie Fairy Tales, and on the television series Quincy, ME. Reeves also appeared on game shows such as Hollywood Squares. In 1977, with the help of former Motown producer Frank Wilson, Reeves became a born-again Christian, joining the Mt. Zion Missionary Baptist Church, pastored by Rev. EV Hill. She released one album on Arista, working with Clive Davis, the Chairmen of the Board's General Johnson and others, and two albums on the Fantasy label, working with other former Motown colleagues Hank Cosby and Holland, Dozier and Holland. In 1983, she performed solo on the famed Motown 25 special. She then performed in a Broadway production of Ain't Misbehavin' and reunited with original members of the Vandellas in 1989 both on record (recording for the London-based Motorcity Records that year issuing the single "Step into My Shoes") and on tour. In 1995, Reeves and the Vandellas were inducted to the Rock & Roll Hall of Fame and were inducted to the Vocal Group Hall of Fame in 2003. Martha performed as part of the halftime show of Super Bowl XXXII in 1998, with her sisters, and current Vandellas, Lois and Delphine Reeves. In 2004, Reeves released her first album in 24 years, Home to You, with songs she wrote and produced herself except for a Billie Holiday cover and an updated version of her big hit, "Jimmy Mack". Between leaving the Vandellas and her solo career, Martha served as an early contributor to the music newspaper, Soul, for which she was honored for by the Black Women in Publishing organization. She was also honored for her best-selling 1995 autobiography, Dancing in the Street.
