23、Societies in which value is measured primarily in financial terms invariably fragment into isolated social units. But since money is not the main measure of value in nonindustrial societies, they must tend in contrast to be socially unified.

The flawed reasoning in which one of the following is most similar to that in the argument above?

(A) Animals of different genera cannot interbreed. But that does not prove that jackals and wolves cannot interbreed, for they belong to the same genus.

(B) Ecosystems close to the equator usually have more species than those closer to the poles. Thus, the Sahara Desert must contain more species than Siberia does, since the latter is farther from the equator.

(C) Insects pass through several stages of maturation: egg, larva, pupa, and adult. Since insect are arthropods, all arthropods probably undergo similar maturation processes.

(D) Poets frequently convey their thoughts via nonliteral uses of language such as metaphors and analogies. But journalists are not poets, so surely journalists always use language literally.（D）

(E) Technologically sophisticated machines often cause us more trouble than simpler devices serving the same function. Since computers are more technologically sophisticated than pencils, they must tend to be more troublesome.

Societies in which value is measured primarily in financial terms invariably fragment into isolated social units. But since money is not the main measure of value in nonindustrial societies, they must tend in contrast to be socially unified.

A  → B (A is societies in which value is measured by money, B is isolated social units)

C is not A (C is that, money is not the main measure)

Therefore, C  → B negative (B negative is that, the society is socially unified as opposed to isolated social units)

Only D mataches this structure.
