Solution
The correct answer is option 3. The passage portrays the British-era forestry system as one that usurped villagers' rights, prioritized revenue and commercial exploitation, and was driven by railway timber needs. Stating that the German experts brought in to manage Indian forests were themselves known for violating indigenous communities' rights would actually reinforce, not weaken, the passage's narrative of colonial forestry harming local populations. Because this claim aligns with the passage's critical stance toward the colonial forest apparatus, it does not weaken the narrative and is therefore the correct choice for the EXCEPT question.
Option 1 is wrong as a choice for EXCEPT (it weakens the narrative). The passage depicts tribals as victims with longstanding claims on forests. If tribals were actually responsible for mass-scale deforestation contributing to climate change, it would undermine the passage's portrayal of them as rightful, sustainable users of forest resources.
Option 2 is wrong as a choice for EXCEPT (it weakens the narrative). The passage argues that colonial usurpation of forest rights had "little precedent in precolonial history." If precolonial Indian rulers also denied peasants and tribals access, this would directly contradict that claim and weaken the narrative.
Option 4 is wrong as a choice for EXCEPT (it weakens the narrative). The passage attributes the origin of the Indian Forest Department and the 1878 Act to massive deforestation caused by railway timber needs. If that timber was actually imported from China, the entire causal chain linking railways to domestic deforestation to the creation of the forest bureaucracy would collapse, significantly weakening the narrative.
