阅读下面短文,从每题所给的三个选项(A、B和C)中,选出最佳选项。

    Thousands of years ago, people only ate food that was grown near their homes. Some kinds of food were

only grown in one place, so people from other places didn't know about them. When Europeans first traveled

to Central and South America in the 1500s, they discovered strange kinds of food that they had never seen

before. Today, these are grown in a lot of different countries and they're sold in supermarkets all over the

world. They don't seem strange any more!

    Potatoes were first grown in the Andes in South America. In 1586, they were taken to Europe by explorers (探险家). In 1719, they were taken to North America. Before 1719, nobody in North America had ever seen

or eaten a potato. Today each American eats more than 60 kilos of potatoes a year.

    Tomatoes were also first grown by native (本地的) Americans. When European explorers visited the south

of America in 1500, they took tomato seeds (种子) back to Europe. Soon, tomatoes were grown in Europe,

but people in England didn't eat them. At that time, a lot of English people thought that tomatoes were

poisonous!

    Chilies (辣椒) have been eaten in Central and South America for more than 8,000 years! In the 1500s,
