Deep within a sandstone mountain on the Norwegian island of Spitsbergen lies the Svalbard Global Seed Vault, often referred to as the "Doomsday Vault." Designed to withstand natural and man-made disasters, the facility serves as a safety net for the world's agricultural biodiversity. It stores millions of seed samples from across the globe, preserving them in sub-zero temperatures. In the event of a global catastrophe or localized crop failure, these seeds can be retrieved to restart agricultural production.
While some critics argue that the resources spent on the vault would be better utilized in supporting active farming communities, proponents emphasize its long-term security benefits. Indeed, the vault has already proved its value. In 2015, researchers from the Middle East withdrew seeds to replace a gene bank destroyed by conflict. __________
Which of the following sentences, if added at the placeholder, would provide the most effective conclusion to the passage by reinforcing its main theme?
- AThis successful retrieval showed the vault is a functional safety net, it highlighted the importance of preserving agricultural history.
- This successful retrieval demonstrated that the vault is not merely a precautionary concept, but a crucial safeguard for the future of global food security.Answer
- CBy restoring these lost crops, the researchers stabilize the local food supply and helped rebuild the region's agricultural economy.
- DUltimately, the vault is located in a permafrost zone that keeps the seeds frozen at a temperature of even if the electricity fails.
