Diffusion will continue to occur between the inside and the outside of a cell until what is reached?
a. active transport
b. equilibrium
c. osmosis
d. passive transport

The correct answer is B (Equilibrium).

Diffusion will continue to occur until a state of equilibrium is attained.

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. The molecules will tend to move into any space available until they are evenly distributed  throughout this space.

When there is no longer a concentration gradient, there will be no net movement of molecules from one area to another. This state is known as dynamic equilibrium. 

i don't know what the picture looks like but i can take a guess and say maybe basidiomycetes?

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.
