(单选题)
Sweet potatoes are good to people because they are rich in ______.
A.fat
B.vitamin A
C.sugar
D.Beta-Carotene
参考答案:D
参考解析:
细节理解题。根据第十段“This powerful Beta-Carotene gives sweet potatoes their yellow, gold, or orange coloring and changes to vitamin A in your body. It’s thought to reduce the risk of certain types of cancer and provide protection against heart disease.”可知β-胡萝卜素可在人体中转化成维生素A,减少癌症危险,提供抗心脏病的物质,所以对身体有好处。fat意为“脂肪”;vitamin A意为“维生素A”;sugar意为“糖”;Beta-Carotene意为“β-胡萝卜素”。故选D。
