Describe the idea of thinking of sentences as having both a ""surface structure"" and a ""deep structure"". also answer the following: does ""movement"" happen at surface or deep structure?

Deep structure is the underlying abstract structure that determines its semantic interpretation. Surface structure is the superficial organization of units that determines phonetic interpretation and relates to the physical form of actual oral expression, its perceived or intentional form. Important to remember that the deep and surface structure need not be identical. The underlying organization of a sentence, which is important for semantic interpretation, is not necessarily revealed by the actual arrangement and method of expression of its components.

The movement from the deep structure to the surface structure necessarily involves the process of deletion, generalization and distortion. Many important clues about the deep structure, however, are expressed and reflected in the structure of the verbal surface.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
