问题：

据测定，香水和化妆品中，有多种物质极易挥发。大多数芳香剂对神经系统有毒，少数还可导致造血系统损害，对皮肤黏膜有刺激作用等。对一般人来说，偶尔地使用芳香剂不至于造成危害，但它们化学成分复杂，且均系交叉使用，故会产生一些目前还无法预料的化学反应。应注意观察其长期积累所产生的后果。对于家庭内有哮喘、呼吸系统疾病、皮肤病、过敏等症状者，最好少用或不用芳香剂。
这段话支持的主要观点是( )。

A．含有芳香剂的香水和化妆品对所有人都有潜在的危害
B．对一般人来说，偶尔地使用芳香剂，不至于造成危害
C．对于家庭有哮喘等疾病的人最好不用芳香剂
D．并非所有的香水和化妆品对人都有毒

Passage Four

Adam Smith was the founder of economics as a distinct field of study. He wrote only one book on the subject — The Wealth of Nations, published in 1776. Smith was 53 years old at the time. His friend David Hume found the book such hard going that he doubted many people would read it. But Hume was wrong — people have been reading it for more than 200 years now.
The Wealth of Nations, in Smith’s view, was the result not of accumulating gold or silver, as many of that time believed, but of ordinary people working and trading in free markets. To Smith, the remarkable thing about the wealth produced by a market economy is that it does not result from any organized plan, rather, it is the unintended outcome of the actions of many people, each of whom is pursuing the incentives the market offers with his or her own interests in mind.
"It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest, every individual is continually exerting himself to find out the most advantageous employment for whatever capital he can command. By directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was a part of his intention".
Much of the discipline of economics as it has developed over two centuries consists of elaboration of ideas found in Smith’s work. The idea of the "invisible hand" of market incentives that channels people’s efforts in directions that are beneficial to their neighbors remains one of the most durable of Smith’s contributions.

In Smith’s view, in pursuing his own interest, one is held by ______.

A．a visible hand

B．an invisible hand

C．a profitable hand

D．a cold hand
