Octopuses have long fascinated biologists because they solve complex puzzles, recognize individual humans, and even use coconut shells as portable shelters. Recent neurological studies suggest that much of this intelligence is distributed throughout their eight arms, each of which contains a dense cluster of neurons capable of processing information independently of the central brain.
Which choice best states the main idea of the text?
- A
Neurological studies of octopuses are a recent development.
- B
Octopuses are smarter than most other invertebrates.
- C
Coconut shells are commonly used by octopuses as shelters.
- Dcheck_circle
Octopus intelligence appears to be partly distributed across their arms rather than centralized.
Explanation
The passage opens with examples of octopus intelligence and then narrows to the recent finding that this intelligence is distributed in the arms. Choice B captures that central claim. A overstates; C and D are supporting details.
