Question
[4]. Passage: The deep sea remains the least mapped environment on Earth, darker, colder and under greater pressure than any place humans routinely visit. Submersibles have revealed hydrothermal vents where life thrives without sunlight, challenging textbook accounts that tied all food chains to photosynthesis. Yet each expedition also exposes how sampling bias distorts knowledge: vents and ridges are studied intensively while vast abyssal plains are barely sampled. Claims about mineral wealth or new species therefore rest on fragments. Honest exploration must report what was not seen, protect fragile vents from hasty extraction, and accept that the ocean floor will revise many confident generalisations. According to the passage, which statement is correct?
Option 2 : Life around hydrothermal vents thrives without sunlight, challenging accounts that tied all food chains to photosynthesis.
