Why could wrong understanding of seasons become the gravest crisis on pastoral routes?

Correct answer: The herd could be trapped in unsuitable weather or empty pasture

The direct answer is A: the herd could be trapped in unsuitable weather or an empty pasture. Seasonal knowledge means understanding when rain, heat, cold, snow or dry periods occur and when particular grazing grounds will have water and grass. Pastoralists planned routes around this knowledge. Step by step: the wrong season may bring little grass or water; insufficient food weakens animals; extreme weather may cause illness or death; weak or dead animals reduce milk, wool, meat and other income; therefore the family’s livelihood is threatened. Option A correctly shows the chain from wrong timing to empty pasture, poor herd health and economic loss. Option B is wrong because unsuitable timing normally reduces, rather than immediately increases, animal productivity. Option C is wrong because a mistake about seasons cannot magically shorten a physical route. Option D is wrong because markets do not always close merely because seasonal knowledge is wrong. The key lesson is that timing was as important as distance. Memory cue: wrong season means wrong pasture, weak herd and lower income.
