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: Did Ivan's brother die in battle? Passage:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the BulgarianVlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.

Example Input: Question: Which of the battles La Hire fought with Dunois was the deadliest? Passage:La Hire joined Charles VII in 1418, when the English army invaded France. Although not a noble, La Hire was regarded a very capable military leader as well as an accomplished rider. Three years later, in 1421 he fought at the Battle of Bauge. Along with Jean de Dunois, La Hire was involved in scouting and skirmishing in the countryside as far north as Paris. In 1427, both La Hire and Dunois relieved the siege of Montargis. He was a close comrade of Joan of Arc. He was one of the few military leaders who believed in her and the inspiration she brought, and he fought alongside her at Orleans. At the Battle of Patay, La Hire commanded the vanguard and won a great victory for France. La Hire was also known for praying before going into battle, something that could be attributed to Joan's influence. In 1430, La Hire captured the English held fortification of Chateau Gaillard. He was imprisoned in Dourdan in the spring of 1431. He won the Battle of Gerberoy in 1435 and was made Captain General of Normandy in 1438. His last two major military engagements occurred in 1440 at Pontoise where he assisted Dunois to capture it from the English; and in 1442 he assisted Charles of Orleans in capturing La Reole. He died at Montauban on 11 January 1443, of an unknown illness.

Example Input: Question: How many songs on What To Do About Them had been previously unreleased? Passage:In 1992 the band signed to Taang! Records and released the eight-song mini-album What To Do About Them culled from a mix of previously available and unreleased home and studio recordings. Musician/cartoonist Ron Rege, Jr. contributed artwork to the album's cover as well as lo-fi recordings that were woven into the record's sequence. The band also set to work recording their first LP, around which time shifts in Swirlies' personnel began to occur. Ben Drucker only drummed on a third of the new album's studio tracks, and for the remaining songs his parts were handed over to a pair of session drummers. Andy Bernick departed to pursue ornithology for the academic year and Damon's former roommate Morgan Andrews filled in on bass guitar and other noises. It was this line-up that toured to support the new album, Blonder Tongue Audio Baton, and appeared in the video for its lead track, "Bell". Named for an obscure piece of vintage musical equipment, Blonder Tongue Audio Baton made use of Mellotron, Moog, and other analogue artifacts that the group had unearthed in the studio. During sequencing the band threw in numerous lo-fi compositions, soundbites, and rants, and collaged together an album jacket from arrays of found images and objects that matched the album's eclectic aesthetics. Hailed for melding "the high waters of shoegaze creativity and the mounting currents of indie rock", Blonder Tongue Audio Baton quickly rose to prominence in the American noise pop canon.
