The skill of Kalang people was in what work?

Correct answer: Forest cutting

The direct answer is B: the Kalangs were skilled in forest cutting. In the history of Java, the Kalangs were a forest community known for specialist work connected with forests, including cutting trees and supplying forest products. To solve the question, focus on the word “skill,” not merely on a general occupation. The lesson is that colonial forest policies often depended on communities that already understood trees, terrain, tools and forest labour. Step by step: the question names the Kalangs; the chapter links them with Java’s forest society; their recognized expertise was forest cutting; therefore option B is correct. Option A, sea dance, is wrong because it is not the historical occupation or skill associated with the Kalangs. Option B is correct because forest cutting was the specific work for which they were considered skilled. Option C, cotton weaving, is wrong because textile work is not the characteristic forest-related skill identified in this lesson. Option D, railway exam, is wrong because an examination is not a traditional occupation, and it has no connection with the Kalangs’ role in Java’s forests. The memory cue is “Kalangs = Java’s forest cutters.” Do not confuse them with every worker in the forest or with railway labourers; the important textbook association is their skill in cutting trees and working in forest areas.
