(单选题)
Why smog has become a common concern?
A.Because we have to develop industry.
B.Because nobody can avoid it.
C.Because people have to pay higher prices.
D.Because a popular online-post discussed it.
参考答案:B
参考解析:
细节理解题。根据第四段第一句“Smog especially is a common concern. Like a popular online post said, air may be the only thing that is equal for everyone, despite your income or vocation. but they breathe the same air as everyone else”可知,尤其是烟雾是人们普遍关心的问题。就像一个流行的在线帖子说的,空气可能是唯一对每个人都公平的东西,不管你的收入或职业。但他们和其他人呼吸同样的空气。由此判断,烟雾问题受所有人关心,因为没有人可以避免它。故选B。
