 ### Behavior Specification
 
 - `balanceOf` **MUST** return the total balance of tokens held by an account that are still valid (i.e., have not expired). This includes any tokens associated with specific epochs, provided they remain within their validity duration. Expired tokens **MUST NOT** be included in the returned balance, ensuring that only actively usable tokens are reflected in the result.
-- `balanceOfAtEpoch` **MUST** returns the balance of tokens held by an account at the specified `epoch`, If the specified epoch is expired, this function **MUST** return `0`.
+- `balanceOfAtEpoch` **MUST** return the balance of tokens held by an account at the specified `epoch`. If the specified epoch is expired, this function **MUST** return `0`.
 For example, if `epoch` 5 has expired, calling `balanceOfByEpoch(5, address)` returns `0` even if there were tokens previously held in that epoch.
 - `currentEpoch` **MUST** return the current `epoch` of the contract.
 - `epochLength` **MUST** return duration between `epoch` in blocks or time in seconds.
