Example Input: Question: What other songs were featured on the Spider-Man 2 soundtrack? Passage:In 1990 the band signed with EMI Records and released their debut album, Strings. Their initial experiments with synthesised sounds and rhythms were not immediately recognised, although Strings sold 20,000 copies during its first week after release. Two years later the band released their second album, 2, which included the critically acclaimed single "Sar Kiye Yeh Pahar". The song was first aired on MTV Asia, and led the band to widespread fame. After the release of 2, the quartet disbanded to focus on their studies and careers. In 2000 Maqsood and Kapadia released Duur, which revived the band's popularity, and followed it with Dhaani in 2003. This album included the single "Najane Kyun", which was part of the soundtrack for the Hollywood film Spider-Man 2. Following Junoon and Nusrat Fateh Ali Khan, Strings went to India (where they found remixes of one of their early songs playing in clubs). In 2008 Strings released their fifth album, Koi Aanay Wala Hai, with the singles "Yeh Hai Meri Kahani" and "Aakhri Alvida" (included on the soundtracks for Bollywood's Zinda and Shootout at Lokhandwala). The album was co-produced by Bollywood actor John Abraham, and was successful in Pakistan and India.

Example Input: Question: Did the trade affect the Aleut people negatively? Passage:The maritime fur trade brought the Pacific Northwest coast into a vast, new international trade network, centered on the north Pacific Ocean, global in scope, and based on capitalism, but not, for the most part, on colonialism. A triangular trade network emerged linking the Pacific Northwest coast, China, the Hawaiian Islands (only recently discovered by the Western world), Britain, and the United States (especially New England). The trade had a major effect on the indigenous people of the Pacific Northwest coast, especially the Aleut, Sugpiaq, Tlingit, Haida, Nuu-chah-nulth, and Chinook peoples. A rapid increase of wealth occurred among the Northwest Coast natives, along with increased warfare, potlatching, slaving, and depopulation due to epidemic disease. However, the indigenous culture was not overwhelmed by rapid change, but actually flourished. For instance, the importance of totems and traditional nobility crests increased, and the Chinook Jargon, which remains a distinctive aspect of Pacific Northwest culture, was developed during this era. Native Hawaiian society was similarly affected by the sudden influx of Western wealth and technology, as well as epidemic diseases. The trade's effect on China and Europe was minimal, but for New England, the maritime fur trade and the significant profits it made helped revitalize the region, contributing to its transformation from an agrarian to an industrial society. The wealth generated by the maritime fur trade was invested in industrial development, especially textile manufacturing.

Example Input: Question: Who won the World Cup where the Costa Rican team had a prominent performance? Passage:Since the late 1980s, the team has continuously been visible as a solidly competitive side, with a prominent performance in the 1990 FIFA World Cup in Italy, making it to the knockout stage in their debut after finishing second in their group during the first phase, below Brazil. They also managed to qualify for the 2002 and 2006 FIFA World Cups. In 2014, Costa Rica made their best performance in history by finishing first in their group that consisted of three former World Cup champions: Uruguay, Italy, and England. During the Round of 16 they defeated Greece 53 via a penalty shootout after a 11 draw. Moreover, during the match against a much better team, Navas saved more than 15 shots due to the Costa Rican very weak defense. The match was characterized as "Navas vs Greece". They reached the quarterfinals for the very first time as the Ticos were defeated by the Netherlands also in a penalty shootout (34) after a scoreless draw on 5 July. Their 2018 World Cup campaign ended in a 4th place group stage exit with their only point coming from a 2-2 draw vs Switzerland.
