Correct Option (D)
The passage explicitly states that nature made man's "natural wants greater than his individual powers" and that "No one man is capable, without the aid of society, of supplying his own wants". These unmet individual needs, acting upon every individual, "impel the whole of them into society". Therefore, the most logical inference is that diverse natural wants compelled individuals to form a social system to collectively address these needs.
Incorrect Options:
-
Option (A) Nature has created a great diversity- in human society: While human societies exhibit diversity, the passage primarily focuses on the fundamental reason for the formation of society itself, which is the inadequacy of individual powers to meet natural wants, rather than the resulting diversity.
-
Option (B) Any given human society is always short of its wants: The passage highlights that individual powers are insufficient to meet individual wants, leading to the formation of society. It does not assert that society, once formed, is perpetually short of its collective wants. Society is presented as a mechanism to overcome individual shortcomings.
-
Option (C) Social life is a specific characteristic of man: The passage indeed implies that man is suited for social life. However, it goes further by explaining the underlying cause for this characteristic – the necessity arising from individual limitations in fulfilling wants. This makes "Diverse natural wants forced man towards social system" a more comprehensive and logical inference that captures the causal relationship presented.
