What was the place of tax in pastoralists' problems?

Correct answer: Tax increased the cost of animal rearing

A grazing tax was a payment imposed on pastoralists for using grazing land or pasture routes. Pastoral families depended on common grazing areas to feed their animals. When colonial authorities introduced or increased such taxes, pastoralists had to spend more money or earn more to maintain their herds. The tax therefore added to the economic pressure already caused by restrictions on movement and shrinking pasture. It did not create new pastures or remove the need for animal rearing.

The question asks how tax fitted into pastoralists’ problems. Option B correctly explains that tax increased the cost of rearing animals. A denies the difficulty, C reverses the effect of taxation, and D is unrelated because the issue concerned pastoral use of land, not the sea. Thus B follows from the economic burden created by grazing taxes.
