Read each short passage below carefully. Match each passage with the unstated central claim (implicit main idea) it best supports.
- Inside long-term agricultural vaults, stored seeds are kept at sub-zero temperatures with oxygen levels lowered to a minimum. Technicians strictly monitor relative humidity to prevent mold and halt cellular metabolism before storage containers are sealed.Preserving seed dormancy over long periods depends on tightly regulated environmental conditions.
- A woodworker begins restoring a dull hand plane by rubbing the steel blade across a coarse whetstone. Once the basic edge is shaped, the craftsman transitions to medium and ultra-fine polishing stones with light oil to remove microscopic metal burrs.Achieving a precision cutting edge requires a progressive, multi-stage sharpening process.
- The desert kangaroo rat survives in arid regions without access to open water. It extracts all required moisture from the carbohydrates inside dry seeds and produces highly concentrated waste to prevent any internal fluid loss.Biological adaptations enable certain desert animals to meet all hydration needs without drinking water.
Cevap
Passage 1 matches the claim regarding environmental controls for preserving seed dormancy; Passage 2 matches the claim regarding the progressive process of sharpening; Passage 3 matches the claim regarding physiological adaptations for survival without liquid water.
Each passage provides a coherent set of factual details that lead to an unstated overarching conclusion: the seed vault passage points to controlled environmental preservation, the tool passage points to graduated sharpening, and the kangaroo rat passage points to hydration adaptations.
