[单项选择]Most economists in the United States seem excited by the spell of the free market. Consequently, nothing seems good or normal that does not accord with the requirements of the free market. A price that is determined by the seller or, for that matter, established by anyone other than the aggregate of consumers seems harmful. Accordingly, it requires a major act of will to think of price-fixing (the determination of prices by the seller) as both "normal" and having a valuable economic function. In fact, price-fixing is normal in all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixing that it requires. Modern industrial planning requires and rewards great size. Hence, a comparatively small number of large firms will be competing for the same group of consumers. That each large firm will act with consideration of its own needs and thus avoid selling its products for more than its competitors charge is
A. refute the theory that the free market plays a useful role in the development of industrialized societies.
B. argue that price-fixing, in one form or another, is an inevitable part of and benefit to the economy of any industrialized society.
C. show that in industrialized societies price-fixing and the operation of the free market are not only compatible but also mutually beneficial.
D. explain the various ways in which industrialized societies can fix prices in order to stabilize the free market.

[单项选择]Anatomy
1. The term anatomy comes from Greek anatomy, "dissection". It is a branch of natural science dealing with the structural organization of living things. The proper understanding of structure, however, implies a knowledge of function in the living organism. Anatomy is therefore almost inseparable from physiology, which is sometimes called functional anatomy.
2. It is convenient to subdivide the study of anatomy in several different ways. One classification is based on the type of organisms studied, the major subdivisions being plant anatomy and animal anatomy. Animal anatomy is further subdivided into human anatomy and comparative anatomy, which seeks out similarities and differences among animal types. Anatomy can also be subdivided into biological processes, for example, developmental anatomy, the study of embryos, and pathological anatomy, the study of diseased organs.
3. The oldest known systematic study of anatomy is contained in an Egyptian papyrus dating from about
