Complete the passage logically by providing the missing conclusion.
Cevap:During the late nineteenth century, transoceanic telegraph cable networks relied on gutta-percha—a natural latex resin—for underwater insulation. Because gutta-percha harvested from tropical trees degraded rapidly when exposed to ambient air and sunlight, storing it in land-based facilities often rendered it unusable before manufacturing began. However, when continuously submerged in cold water, the material retained its chemical stability and structural flexibility indefinitely. Consequently, cable suppliers realized that rather than constructing costly climate-controlled land storage warehouses, they could preserve harvested resin prior to shipping simply by 【storing it underwater in local aquatic basins】.
Cevap
Submerging the harvested resin in cold water reservoirs or local aquatic basins prior to shipping.
The passage establishes two key facts: exposure to air and sunlight degrades harvested gutta-percha, whereas continuous submersion in cold water preserves it indefinitely. Therefore, to avoid the high cost of climate-controlled land warehouses, the most direct and logical solution is to store the harvested material submerged in cold water.
