Passage A
For decades, deep-sea oceanography relied on tethered instruments and remote sensors, leaving the vast abyss largely abstract to human perception. The advent of crewed submersibles altered this paradigm by placing human observers directly inside the benthic environment. There is an irreplaceable cognitive advantage to direct human sight and real-time sensory processing. A researcher gazing through a pressure hull can perceive subtle shifts in bioluminescence, micro-topography, and organismal behavior that video feeds invariably flatten. Human presence allows for spontaneous decision-making—shifting a dive plan instantly when an unpredicted hydrothermal structure appears. While robotic probes have expanded data collection metrics, reducing ocean exploration to automated data points strips marine biology of the serendipitous discoveries that only an observant human mind, experiencing the deep environment firsthand, can achieve.
Passage B
The argument that deep-ocean science requires human presence inside submersibles is increasingly anachronistic and financially inefficient. Modern Autonomous Underwater Vehicles (AUVs) and remotely operated robotics can remain submerged for weeks, sampling environmental DNA, mapping bathymetry with high-resolution sonar, and collecting delicate biological specimens with sub-millimeter precision. Crewed dives, by contrast, consume exorbitant budgets, risk human lives, and restrict operational time to mere hours due to oxygen and power constraints. Furthermore, human sensory observation is inherently subjective and prone to observational bias, whereas calibrated sensors generate standardized, reproducible datasets essential for modern ecological modeling. Oceanography must transition away from romanticized human expeditions and allocate its limited funding toward scalable, long-duration robotic fleets that yield far greater empirical value.
Which statement best describes the difference in perspective between the author of Passage A and the author of Passage B regarding human presence in deep-sea exploration?
- The author of Passage A regards direct human observation as essential for spontaneous discovery, whereas the author of Passage B views human presence as inefficient and secondary to standardized robotic data collection.Cevap
- BThe author of Passage A advocates for abandoning robotic probes entirely, whereas the author of Passage B claims that robotic probes cannot collect delicate biological specimens.
- CBoth authors agree that human submersibles are overly expensive, but the author of Passage A urges private funding while the author of Passage B supports public grants.
- DThe author of Passage A dismisses technological instrumentation as useless, whereas the author of Passage B adopts a purely neutral, uncritical stance toward crewed submersibles.
