Final answer:
The word 'replenished' in paragraph 2 means to be built up again. This is in relation to the Svalbard Global Seed Vault, which helps maintain crop diversity by storing a backup of seeds from around the world.
Step-by-step explanation:
In paragraph 2 of the passage, the word ‘replenished’, derived from Latin ‘plenus’ meaning “full”, most accurately means to be built up again. The construction of the Svalbard Global Seed Vault is a direct response to the concern for our decreasing plant diversity and represents an essential strategy in safeguarding our global food supply.
By storing seeds from around the world, the vault provides a way to maintain crop diversity and serves as an insurance policy against potential loss of varieties in regional seed banks due to accidents, natural disasters, and other unforeseen events.
