The chapter says that the discovery of fire 'led to many other developments'. Which best captures the pattern this example illustrates?
ADiscoveries are random and unrelated
BEach major discovery or invention enables further discoveries — cumulatively expanding what humans can use as resources
CDiscoveries always reduce resource availability
DDiscoveries only matter if they are written down
Answer & Solution
Correct answer: B. Each major discovery or invention enables further discoveries — cumulatively expanding what humans can use as resources
The text uses fire and the wheel as examples of a deeper principle: discoveries enable further discoveries. Fire allowed cooking, smelting metals, glassmaking and many later technologies. The wheel led to carts, pulleys, gears, and ultimately to modern transport and machinery. Knowledge compounds across generations — each unlock multiplies what comes next.
