(单选题)
According to the passage, what can explain the cats’ loss of ability to taste sweets?
A.Their genetic defect.
B.Their taste preference.
C.Their diet selection.
D.Their preference for meat.
参考答案:A
参考解析:
细节理解题。根据文章第三段第一句“One previous study found that cats, which must eat meat in order to survive, had lost the ability to taste sweets due to a genetic defect”可知,之前的一项研究发现,由于基因缺陷,必须吃肉才能生存的猫失去了品尝甜食的能力。A项意为“它们的基因缺陷”;B项意为“它们的口味偏好”;C项意为“它们的饮食选择”;D项意为“它们对肉的偏爱”。所以熊猫之所以是失去品尝甜食是因为基因缺陷。故选A。
