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: Who did Eintracht Frankfurt defeat in the 1959 German Championship? Passage:His club was Eintracht Frankfurt with whom he won the 1959 German Championship, and in 1960 reached the finals of Champion's Cup against Real Madrid. The left-footed Don Alfredo was the head of the team. Pfaff was a true playmaker with exceptionally good ball control and great skills at free kicks. Pfaff probably would have accumulated more than seven caps if Fritz Walter had not played the same role for West Germany as Pfaff played for Eintracht Frankfurt. In 1954, Atlético Madrid offered him 180,000 D-Mark but his wife Edith was against a move to Spain. Possibly Pfaff's greatest game was the 6–1 against Rangers F.C. in the 1959–60 semifinal first leg of the European Champion Clubs' Cup, which was followed by a 6–3 win of Eintracht Frankfurt in Glasgow in the second leg. He ended his career in 1962 at the age of 36.

Example Input: Question: Of the band Fanny's first two albums, which had the longer total run time? Passage:Perry produced the band's first three albums, beginning with Fanny in 1970. Because of the connection to Perry and Reprise Records, Barclay was invited to tour with Joe Cocker as a backing singer, and consequently appeared on the album Mad Dogs and Englishmen. The group's cover of Cream's "Badge" from the first album had significant radio airplay. The follow-up album, Charity Ball was released the following year, and its title track reached #40 on the Billboard Hot 100. The members of Fanny also worked as session musicians, and played on Barbra Streisand's 1971 album Barbra Joan Streisand, after Streisand had wanted to record with a small band. The group continued to pick up well-known fans; David Bowie sent the group a letter admiring their work and invited the band to a post-show party where he showed them mime techniques. With young engineer Leslie Ann Jones as their road manager and live sound mixer, Fanny toured worldwide, opening for Slade, Jethro Tull and Humble Pie, gaining widespread popularity in the United Kingdom. A 1971 article in Sounds remarked that the group "seems that they are the support group to everyone these days". The group made several live television appearances during tours, including The Sonny and Cher Show, American Bandstand, The Old Grey Whistle Test and Beat-Club.
