Problem: Background: Rouvas was born on 5 January 1972 in the village of Mandoukion, near Corfu City on the island of Corfu, the eldest of four sons of Konstantinos "Kostas" Rouvas (an ambulance driver) and the teenaged Anna-Maria Panaretou (a duty-free shop clerk at the local airport). He has three brothers: Billy (b. Vasilios), Tolis (b. Apostolos, 1975) and Nikos (b. Nikolaos, 1991). The family was poor, and Rouvas began taking care of his brothers at age five. At age four, he exhibited athletic ability and took ballet classes as a child.
Context: In December 1998 Rouvas released his sixth album (the first with his new label): Kati Apo Mena (Something From Me), written by Giorgos Theofanous. "Den Ehi Sidera I Kardia Sou" ("Your Heart Doesn't Have Steel Rails") was a hit, and remains one of his most-popular songs. To promote the album Rouvas performed at the Virgin Megastore in Athens, where thousands of fans created a traffic jam. The next year, Rouvas records "Oso Exo Esena" ("As Long As I Have You"), a duet with singer Stelios Rokkos. The two artists work and perform together at Bio Bio in Athens during the summer.  In March 2000 Rouvas released his seventh album, 21os Akatallilos (21+ X-Rated), and performed with Katy Garbi at Pili Axiou in Thessaloniki. The album and its first single, "Andexa" ("I Held Out"), reached number one on the charts. During May rehearsals for summer performances Rouvas was hospitalized with abdominal pain, which was diagnosed as peritonitis and required an appendectomy. On 25 October 2000, he began appearing with Antonis Remos and Peggy Zina at Apollonas for the winter season. That year Rouvas became the Pepsi spokesperson for the company's Greek summer campaign making a first television ad, a first for a Greek entertainer. His collaboration with Pepsi continued into 2001, with a May television ad. The advertisement, featuring a semi-nude Rouvas holding a Pepsi bottle in front of his genitals, was controversial among women's rights and parental associations. Calling it "unsightly, vulgar and unacceptable", they tried to have the ad blocked as "disgrac[ing] childhood innocence and dignity." The Pepsi Tour 2001, of seven Greek cities, followed.  During summer 2000 Rouvas, Psinakis and a number of other celebrities visited Mykonos on a yacht borrowed from a local physician. They were accused of drug possession, since the yacht contained narcotics. The incident was publicized amid speculation that Rouvas might have a drug addiction. Although the doctor admitted that the narcotics were his, his guests were questioned. Wishing to avoid court, Rouvas paid a fine and minimized the incident. However, thousands of T-shirts were printed which read: "Imoun ki ego sto kotero!" ("I was on the yacht, too!").
Question: is there anything else interesting about the 21os Akatallilos?
Answer: They were accused of drug possession, since the yacht contained narcotics.

Problem: Background: Vasco da Gama was born in 1460 or 1469 in Sines, on the southwest coast of Portugal, probably in a house near the church of Nossa Senhora das Salas. Sines, one of the few seaports on the Alentejo coast, consisted of little more than a cluster of whitewashed, red-tiled cottages, occupied chiefly by fisherfolk. Vasco da Gama's father was Estevao da Gama, who had served in the 1460s as a knight of the household of Infante Ferdinand, Duke of Viseu. He rose in the ranks of the military Order of Santiago.
Context: From the earlier part of the 15th century, Portuguese expeditions organized by Prince Henry the Navigator had been reaching down the African coastline, principally in search of west African riches (notably, gold). They had greatly extended Portuguese maritime knowledge, but had little profit to show for the effort. After Henry's death in 1460, the Portuguese Crown showed little interest in continuing this effort and, in 1469, sold off the neglected African enterprise to a private Lisbon merchant consortium led by Fernao Gomes. Within a few years, Gomes' captains expanded Portuguese knowledge across the Gulf of Guinea, doing business in gold dust, Melegueta pepper, ivory and sub-Saharan slaves. When Gomes' charter came up for renewal in 1474, Prince John (future John II), asked his father Afonso V of Portugal to pass the African charter to him.  Upon becoming king in 1481, John II of Portugal set out on many long reforms. To break the monarch's dependence on the feudal nobility, John II needed to build up the royal treasury; he considered royal commerce to be the key to achieving that. Under John II's watch, the gold and slave trade in west Africa was greatly expanded. He was eager to break into the highly profitable spice trade between Europe and Asia, which was conducted chiefly by land. At the time, this was virtually monopolized by the Republic of Venice, who operated overland routes via Levantine and Egyptian ports, through the Red Sea across to the spice markets of India. John II set a new objective for his captains: to find a sea route to Asia by sailing around the African continent.  By the time Vasco da Gama was in his 20s, the king's plans were coming to fruition. In 1487, John II dispatched two spies, Pero da Covilha and Afonso de Paiva, overland via Egypt to East Africa and India, to scout the details of the spice markets and trade routes. The breakthrough came soon after, when John II's captain Bartolomeu Dias returned from rounding the Cape of Good Hope in 1488, having explored as far as the Fish River (Rio do Infante) in modern-day South Africa and having verified that the unknown coast stretched away to the northeast.  An explorer was needed who could prove the link between the findings of Dias and those of da Covilha and de Paiva, and connect these separate segments into a potentially lucrative trade route across the Indian Ocean.
Question: Who headed the explorations?
Answer:
John II set a new objective for his captains: to find a sea route to Asia by sailing around the African continent.
