 The `useQuery` hooks always take the cache key argument as the first parameter, and if you need to provide hook options, that must always be the second parameter, like `useSomeQuery(cacheKey, options)`. In this case, the `getUsers` endpoint doesn't have any actual cache key argument. Semantically, this is the same as a cache key of `undefined`. So, in order to provide options to the hook, we have to call `useGetUsersQuery(undefined, options)`.
 
-We can use `selectFromResult` to have `<UserPage>` read just a filtered list of posts from the cache. However, in order for `selectFromResult` to avoid unnecessary re-renders, we need to ensure that whatever data we extract is memoized correctly. To do this, we should create a new selector instance that the `<UsersPage>` component can reuse every time it renders, so that the selector memoizes the result based on its inputs.
