Taxonomy
brings order to understanding the immense diversity of life
is an unnecessary science
is a classification system
is the study of animal behavior

Option (3)

Explanation:

Taxonomy is usually defined as the classification scheme that is applied to all living organisms, including micro-organisms, plants, and animals. The scientists adopted the hierarchical classification method, which enabled them to study their characteristics and categorize the biological diversities on earth. The organisms are prominently and easily identified by comparing their existing characteristics with the different types of categorized species.

Thus, it is a classification system.

Hence, the correct answer is option (3).

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
