The complete question is :

The success of plants extending their range northward following glacial retreat is best determined by .

A) whether there is simultaneous migration of herbivores

B) their tolerance to shade

C) their seed dispersal rate

D) their size

The seed dispersal rate

Explanation:

The  seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.

Plants have very limited ability, they need vectors to carry its seed from one place to another.

The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.

hence, the correct answer is option C

b

is correct hope this   also i learnd this in middle school

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.
