【单选题】第二篇 Puerto Rican Cuisine（菜肴）who lived in Puerto Rico first（） A．the Africans B．the Spanish C．the Americans D．the Taino people
A.

B.
Puerto Rican Cuisine（菜肴）
C.
Puerto Rico, a Caribbean (加勒比海区) island rich in history and remarkable natural beauty, has a cuisine all its own. Immigration（移民） to the island has helped to shape its cuisine, with people from all over the world various contributions to it. However, before the arrival of these immigrants, the Taino people lived on the island of Puerto Rico. Taino cuisine included such foods as rodents (啮齿动物), fresh shellfish and fish fried in corn oil.
D.
Many aspects of Taino cuisine continue today in Puerto Rican cooking, but it has been heavily influenced by the Spanish, who invaded Puerto Rico in 1508, and Africans, who were initially brought to Puerto Rico to work as slaves. Taino cooking styles were mixed with ideas brought by the Spanish and Africans to create new dishes. The Spanish extended food choices by bringing cattle, pigs, goats, and sheep to the island.
E.
Africans also added to the island’s food culture by introducing powerful, contrasting tastes in dishes. In fact, much of the food Puerto Rico is now famous for - coffee, coconuts, and oranges - was actually imported by foreigners to the island. A common assumption many people make about Puerto Rican food is that it is very spicy(辛辣的). lt’s true that chili peppers are popular; aij caballero in particular is a very hot chili pepper that Puerto Ricans enjoy. However, milder(微辣的) tastes are popular too, such as sofrito. As the base of many Puerto Rican dishes, sofrito is a sauce made from chopped onions, green bell peppers, sweet chili peppers, and a handful of other spices. It is fried in oil and then added to other dishes.
