Slime molds — single-celled organisms that can aggregate into larger structures — are unusually good at solving certain optimization problems. In one famous experiment, a slime mold placed on a map of Tokyo, with food at locations of major train stations, grew connections that resembled the actual railway network. The result intrigues biologists less for its design parallels than for what it reveals about distributed decision-making in organisms without brains.
Which choice best states the main idea of the text?
- Acheck_circle
The slime-mold experiment illustrates how distributed, brainless organisms can perform sophisticated optimization.
- B
Slime molds can design train networks.
- C
Single-celled organisms are smarter than animals.
- D
Tokyo has the best train network.
Explanation
The passage's central point is what the result reveals about distributed decision-making — B. A overstates the design framing; C and D are unsupported.
