Question: The 1469 marriage of Isabella I of Castile and Ferdinand II of Aragon and the 1479 death of John II of Aragon led to the creation of modern-day Spain. In 1492, Granada was captured from the Moors, thereby completing the Reconquista. Portugal had during the 15th century particularly under Henry the Navigator gradually explored the coast of Africa, and in 1498, Vasco da Gama found the sea route to India. The Spanish monarchs met the Portuguese challenge by financing the expedition of Christopher Columbus to find a western sea route to India, leading to the discovery of the Americas in 1492.

Question: Queen's last album featuring Mercury, titled Made in Heaven, was finally released in 1995, four years after his death. Featuring tracks such as "Too Much Love Will Kill You" and "Heaven for Everyone", it was constructed from Mercury's final recordings in 1991, material left over from their previous studio albums and re-worked material from May, Taylor, and Mercury's solo albums. The album also featured the song "Mother Love", the last vocal recording Mercury made prior to his death, which he completed using a drum machine, over which May, Taylor and Deacon later added the instrumental track. After completing the penultimate verse, Mercury had told the band he "wasn't feeling that great" and stated, "I will finish it when I come back, next time"; however, he never made it back into the studio, so May later recorded the final verse of the song. Both stages of recording, before and after Mercury's death, were completed at the band's studio in Montreux, Switzerland. The album reached No. 1 on the UK charts immediately following its release, and has sold 20 million copies worldwide. On 25 November 1996, a statue of Mercury was unveiled in Montreux overlooking Lake Geneva, almost five years to the day since his death.
