Read the following passage and answer the items that follow. Your answers to these items should be based on the passages only Nothing can exist in a natural state which can be called good or bad by common assent, since every man who is in a natural state consults only his own advantage, and determines what is good or bad according to his own fancy and insofar as he has regard for his own advantage alone, and holds himself responsible to no one save himself by any law; and therefore sin cannot be conceived in a natural state, but only in a civil state, which is decreed by common consent what is good or bad, and each one holds himself responsible to the state. Which one of the following statements best reflects the central idea of the passage given above?

The central idea of the passage is that the concepts of good, bad, right, or wrong (and sin) do not exist in a natural state but only arise within a civil state. In a natural state, individuals act solely for their own advantage without external laws or accountability. It is the civil state, formed by common consent, that defines these concepts and establishes responsibility.

Let's analyze the options:

A) The conceptions of what is right or wrong exist due to the formation of a state. This statement perfectly reflects the passage. The passage explicitly states, "sin cannot be conceived in a natural state, but only in a civil state, which is decreed by common consent what is good or bad." This directly links the existence of these moral concepts to the formation of a state.

B) Unless a ruling authority decides as to what is right or wrong, no man would be morally right. This option is too strong and slightly misinterprets the passage. The passage focuses on the conception and definition of good/bad by common assent within a state, not on whether an individual man can be "morally right" in an absolute sense without such an authority. It's about the framework, not individual moral status.

C) Man is inherently immoral and selfish in a natural state. While the passage states that man in a natural state "consults only his own advantage" and acts "according to his own fancy," it also explicitly says that "sin cannot be conceived in a natural state." This implies that the very concept of "immoral" does not apply in the natural state, as there is no moral framework. Therefore, man cannot be "inherently immoral" if immorality itself doesn't exist. Selfishness is described, but not immorality.

D) The idea of what is right or wrong is necessary for the survival of human species. The passage does not discuss the necessity of these ideas for the survival of the human species. It focuses solely on the origin and existence of these concepts in relation to the state versus the natural state. This is an external idea not supported by the text.

Therefore, option A best reflects the central idea by accurately capturing the passage's argument that the framework for right and wrong is a product of the civil state.
