单项选择题
All of the following are examples of commodity-linked equities EXCEPT:（）
A. a gold mining company
B. a supermarket operating company
C. an oil and gas exploration company
答案
参考答案：B
解析：
The stocks of a gold mining company, an oil and gas exploration company, and a timber company are highly correlated with commodities prices, because their values are closely linked to the price of the commodities they produce. A supermarket chain will be more diversified, and many other factors will contribute to the value of the company.
