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

Correct answer: Because it also enabled monitoring of animal numbers and grazing activity

The direct answer is A: grazing tax was not only a way to collect money; it also helped the colonial state monitor animal numbers and grazing activity. First, officials required pastoralists to pay for access to grazing areas. To calculate or collect that tax, they needed information about herders, herds and the places where animals grazed. This gave the state greater knowledge and control over mobile communities. Option A is correct because it shows both functions: revenue collection and administrative surveillance. Option B is wrong because a tax does not make pastoralists tax-free; it creates a financial obligation. Option C is wrong because grazing tax did not end forest control. In many cases, taxes worked alongside forest restrictions. Option D is wrong because paying a tax could not automatically create more pastures; the amount of land depends on policy, ecology and land use. The important idea is that colonial taxes were often instruments of control as well as sources of income. Memory cue: tax means money plus information and supervision.
