Hoard

This is a synonym-matching item: it asks for the option closest in meaning and word class to hoard — not its opposite. First fix hoard's sense and part of speech, then match every option against it.

Hoard, used here as a verb, means to gather and store up a stock of something, typically in secret and for future use. Among the options, only Accumulate is a verb carrying that same sense — to collect or build up over time — so it matches both the meaning and the word class of hoard.

Why the other options don't match:

• Reservoir names a place or supply used for storage (for example, a reservoir of water) — a noun for a container or source, not the verb action of gathering and keeping that hoard describes.

• Aggregation names a mass or cluster that has come together — again a noun for the resulting collection, not the deliberate verb action hoard describes.

• Disperse means to scatter or spread out — the direct opposite of gathering and keeping, so it marks the antonym relationship rather than a matching one.

Cross-check from the opposite direction: since disperse is confirmed as hoard's antonym, the option that instead matches hoard in meaning must sit at the other pole of the same spectrum — accumulate — confirming the same conclusion.
