You can increase the strength of an electromagnet’s field by a. decreasing the current in the solenoid. b. decreasing the number of loops in the solenoid. c. using a stronger ferromagnetic material for the core. d. winding the coils more loosely.

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.
