Which problem could increase when grazing tax collection was given to contractors?

Correct answer: Possibility of harsh and excessive collection increased

The direct answer is C: the possibility of harsh and excessive collection increased. A contractor collected grazing tax for the government, usually with an interest in earning profit. The reasoning is: the contractor had to recover the amount expected by the government; profit could come from collecting extra money or using pressure; pastoralists might face higher demands, threats or little flexibility; therefore tax collection could become harsh and exploitative. Option A is wrong because giving collection to contractors did not end the tax. Option B is wrong because tax collection cannot automatically create more pasture. Option C is correct because the profit motive and delegated authority could encourage excessive collection. Option D is wrong because pastoralists remained taxpayers, not tax collectors. Memory cue: contractor plus profit motive can mean stricter collection and greater exploitation.
