Which word means to provide enough of what somebody/something needs in order to live or exist?

• A. Sustain
• B. Devastating
• C. Detergent
• D. Device

Answer: (A)

Sustain means providing ongoing support that lets someone or something continue to live or exist. It implies a steady, enough supply over time—like food, water, shelter, or resources—that keeps life or a system going rather than just a one-time act. That sense of continued adequacy is what links the word most directly to the idea of keeping life or existence going. The other words don’t fit: devastating describes something causing great damage; detergent is for cleaning; a device is a tool or gadget. Only sustain captures the idea of providing the ongoing support required to keep living or existing.
