Thomas Edison is celebrated as the inventor of the light bulb, yet incandescent light was developed by multiple inventors across different countries. Edison's contribution was creating a practical, long-lasting bulb and the electrical distribution system to power it. His genius, some argue, was more entrepreneurial than inventive—integrating components, founding companies, and building markets. The 'lone inventor' narrative obscures collaborative and cumulative aspects of innovation.
The passage suggests that
Edison made no contribution to electric lighting
inventions typically emerge fully formed from single individuals
entrepreneurial work is completely separate from invention
popular narratives about invention may simplify more complex historical processes
Correct Answer: D
Choice D is the best answer. The 'lone inventor' narrative "obscures" the more complex reality.
- Context clues: Edison is celebrated as the inventor; but the bulb was developed by multiple inventors.
- Meaning: The simple story hides that invention is collaborative and cumulative.
- Verify: Edison's actual contribution (integration, commercialization) differs from the narrative.
💡 Strategy: When a well-known narrative is shown to omit complexity, infer simplification.
Choice A is incorrect because Edison contributed practical bulb and distribution system design. Choice B is incorrect because multiple inventors developed the technology. Choice C is incorrect because Edison's entrepreneurial work was his key contribution.
