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: What year was the prize that the Assemble collective received first given out? Passage:Nottingham is a research-led institution, and two academics connected with the university were awarded Nobel Prizes in 2003. Clive Granger was jointly awarded the Nobel Prize in Economics. Much of the work on Magnetic Resonance Imaging (MRI) was carried out at Nottingham, work for which Sir Peter Mansfield received the Nobel Prize for Medicine in 2003. Nottingham remains a strong centre for research into MRI. The university has contributed to a number of other significant scientific advances. Frederick Kipping, Professor of Chemistry (1897–1936), made the discovery of silicone polymers at Nottingham. Major developments in the in vitro culture of plants and micropropogation techniques were made by plant scientists at Nottingham, along with the first production of transgenic tomatoes by Don Grierson in the 1980s. Other innovations at the university include cochlear implants for deaf children and the brace-for-impact position used in aircraft. In 2015, the Assemble collective, of which the part-time Architecture Department tutor Joseph Halligan is a member, won the Turner Prize, Europe's most prestigious art award. Other facilities at Nottingham include a 46 teraflop supercomputer.

Example Input: Question: How many total tracks were there on Born to Die? Passage:After uploading a few of her tracks to her YouTube channel, Del Rey was discovered and got signed by Stranger Records to release her debut single "Video Games". She told The Observer that "Video Games" was never intended to be a single, but she enjoyed the video and uploaded on the internet. The song earned her a Q Award for "Next Big Thing" in October 2011. Later that month, she signed a joint record deal with Interscope Records and Polydor to release her second studio album, Born to Die. Del Rey built anticipation to the album by doing a number of live appearances, such as promotional concerts at the Bowery Ballroom and at the Chateau Marmont, and with performances at television shows such as De Wereld Draait Door, and Later... with Jools Holland. To further promote the upcoming release of Born to Die, Interscope Records released the EP in the United States and Canada on January 10, 2012. The four tracks that appear on the EP ("Video Games", "Born to Die", "Blue Jeans", and "Off to the Races") were previously available for purchase as singles in international markets.

Example Input: Question: Which driver is younger between the nine-time world champion and the one who led him by 7.2 seconds after two days? Passage:Dani Sordo, who targeted himself for a podium finish, led nine-time world champion Sébastien Loeb by 7.2 seconds after two days. Both drivers benefited from low start positions in the sweltering mountain speed tests above León. Ott Tänak, 11 seconds off the pace in third, drove around overheating problems in his Toyota Yaris, ahead of last year winner Kris Meeke. Defending world champion Sébastien Ogier limited his losses from second in the start order in fifth place, despite a spin. Norwegian Andreas Mikkelsen was sixth, only 1.5 seconds behind the Frenchman. It was a nightmare catastrophe for championship leader Thierry Neuville. The road opener fared worst in the conditions and lost more than 20 seconds due to a fuel pressure problem and a power steering issue in his i20. He placed seventh overall when Jari-Matti Latvala retired with alternator problems before SS9. Elfyn Evans retired from the rally because of rolling out though he managed to reach the finish line, while teammate Teemu Suninen and Esapekka Lappi retired from the day due to hitting a barrier and crashing respectively. WRC 2 leader Pontus Tidemand, Gus Greensmith and Pedro Heller completed the top ten.
