PROBLEM: Advances were made in irrigation and farming, using new technology such as the windmill. Crops such as almonds and citrus fruit were brought to Europe through al-Andalus, and sugar cultivation was gradually adopted by the Europeans. Arab merchants dominated trade in the Indian Ocean until the arrival of the Portuguese in the 16th century. Hormuz was an important center for this trade. There was also a dense network of trade routes in the Mediterranean, along which Muslim countries traded with each other and with European powers such as Venice, Genoa and Catalonia. The Silk Road crossing Central Asia passed through Muslim states between China and Europe.

SOLUTION: which crops were brought to europe from the Muslim World?

PROBLEM: In 2005, Argentina's indigenous population (known as pueblos originarios) numbered about 600,329 (1.6% of total population); this figure includes 457,363 people who self-identified as belonging to an indigenous ethnic group and 142,966 who identified themselves as first-generation descendants of an indigenous people. The ten most populous indigenous peoples are the Mapuche (113,680 people), the Kolla (70,505), the Toba (69,452), the Guaraní (68,454), the Wichi (40,036), the Diaguita-Calchaquí (31,753), the Mocoví (15,837), the Huarpe (14,633), the Comechingón (10,863) and the Tehuelche (10,590). Minor but important peoples are the Quechua (6,739), the Charrúa (4,511), the Pilagá (4,465), the Chané (4,376), and the Chorote (2,613). The Selknam (Ona) people are now virtually extinct in its pure form. The languages of the Diaguita, Tehuelche, and Selknam nations have become extinct or virtually extinct: the Cacán language (spoken by Diaguitas) in the 18th century and the Selknam language in the 20th century; one Tehuelche language (Southern Tehuelche) is still spoken by a handful of elderly people.
