Why is it incomplete to call grazing tax only a revenue policy?

Correct answer: Because it also monitored animal numbers and pastoralists

The direct answer is A. A grazing tax did raise revenue, but it also gave officials information and control over pastoral life. To collect the tax, authorities could count animals, identify herders, record their movements or routes, and regulate access to grazing grounds. Thus the tax was not merely a financial charge; it helped make mobile communities visible and administratively manageable. Option A is correct because it includes both animal-number monitoring and surveillance of pastoralists. Option B is wrong because a tax imposes a payment, not tax exemption. Option C is wrong because taxation did not increase pasture; other colonial policies often reduced access. Option D is wrong because tax rules did not automatically open forests. Memory cue: grazing tax means revenue plus records plus control.
