A
In the last 500 years nothing about people-not their clothes, ideas, or languages has changed as much as what they eat. Chocolate drink was first made from the seeds of the cacao (可可) tree by South American Indians. The Spanish introduced it to the rest of the world during the 1500s. And although it was very expensive, it quickly became popular. In London, shops where chocolate drinks were served became important places. Some still exist today. The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the years of 1845-1846, and thousands more were forced to go to live in America.
