Restricted mobility increasing overgrazing supports which wider conclusion?

Correct answer: Pastoralists' free movement was useful for ecological balance too

Pastoral mobility was not only a social or economic practice; it also helped manage natural resources. When herds moved seasonally, grazing pressure was distributed among different pastures. Areas used in one period could recover during another period, depending on rainfall and grass growth. If movement was restricted, many animals had to remain in fewer places for longer periods, making overgrazing more likely. This shows that mobility could support ecological balance.

Option A is correct because it recognizes this broader relationship without claiming that pastoralism was always harmless. The other choices are illogical or reverse the evidence. Pastoralists did not always destroy the environment, tax could not make grass grow, and closing forests did not increase available pasture. A balanced conclusion is that customary movement was an important adaptation and could reduce concentrated pressure on grasslands.
