Which main freedom of African pastoralists did colonial rule restrict?

Correct answer: Freedom to move in search of pastures

Direct answer: Option A is correct. Pastoralism requires movement because grass and water are not available in the same place throughout the year. African pastoralists traditionally moved their herds to seasonal pastures and water sources. Colonial governments introduced fixed borders, reserves, private land rules and permits. These controls stopped or restricted movement across old grazing routes. Option A correctly identifies the freedom that was limited: moving in search of pasture. Option B is wrong because sailing ships was not the central freedom on which pastoral livestock production depended. Option C is wrong because building factories was unrelated to pastoral mobility. Option D is wrong because colonial mining laws were not the main freedom described here; pastoralists were primarily affected by restrictions on land use and movement. The reasoning is: livestock need changing resources; pastoralists therefore move; colonial boundaries and reserves blocked movement; access to pasture and water became harder. A weak student should distinguish mobility from unrelated industrial or maritime activities. Memory cue: colonial rule often changed mobile pastoral life into restricted movement.
