Example Input: Passage: Salvatore di Pietro was born in Palermo, Italy, on 15 June 1830. He entered the Society of Jesus (Jesuits) in October 1845 and was ordained a priest on 2 June 1859. He arrived in British Honduras (now known as "Belize") on 22 March 1869. On May 12 he suffered an attack of yellow fever. His superiors transferred him to Guatemala, where he preached missions to the Garifuna. He was appointed head of the missions in northern Guatemala, but along with 80 other Jesuits fled the country in September 1871 when the Liberals gained control and persecuted the Catholic Church. In 1872 president Jose Maria Medina invited him to Spanish Honduras to found a college in the capital Comayagua. He began by preaching missions in Omoa and San Pedro Sula. However, the Liberals took control of Spanish Honduras also and he returned to Belize.

Example Input: Passage: "Look Out Cleveland" is the title of the Robbie Robertson-written song on The Band's self-titled album, also known as The Brown Album. The song begins with a boogie-woogie blues riff by pianist Richard Manuel followed by lead singer Rick Danko warning -- "Look out Cleveland, storm is coming through, And it’s runnin’ right up on you". However the Cleveland referenced in the song is not Cleveland, Ohio but likely Cleveland, Texas, a suburb of Houston which is also mentioned in the chorus -- "Look out, Houston, there’ll be thunder on the hill...". "Look Out Cleveland" differs from most of the songs on The Band's first two albums in that is more influenced by urban blues music than by rural music. According to music critic Nick DeRiso, Elton John's early song "Take Me to the Pilot" appears to be influenced by this song.
 Link Information: Richard Clare Danko (December 29, 1943 – December 10, 1999) Question: Who is older between the lead singer and pianist on the song?
Example Output: Answer: Richard Manuel

He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaúlza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation.
