There is evidence that a certain ancient society burned large areas of land. Some suggest that this indicates the beginning of large-scale agriculture in that society—that the land was burned to clear ground for planting. But there is little evidence of cultivation that this society was still a hunter-gatherer society.
What this question is testing
Conclusion
This ancient society was probably still in the hunter-gatherer phase, not farming.
Evidence
They burned huge tracts of land. Some archaeologists said: "Agriculture! They were clearing fields!" But when you look at the ground after the fires, there is no evidence anyone planted anything. So probably not agriculture.
Evaluate
The "not agriculture" part is solid — no crops after the fire is a pretty good clue. But the argument still needs to explain what hunter-gatherers were doing with all that fire. Right now it is: That last step needs a reason. If hunter-gatherers had their own reasons for large-scale burning, the conclusion gets much stronger.
Goal
Find the answer that gives hunter-gatherers a reason to play with fire on a grand scale.
