/**
 * A hook for executing queries in an Apollo application.
 *
 * To run a query within a React component, call `useQuery` and pass it a GraphQL query document.
 *
 * When your component renders, `useQuery` returns an object from Apollo Client that contains `loading`, `error`, and `data` properties you can use to render your UI.
 *
 * > Refer to the [Queries](https://www.apollographql.com/docs/react/data/queries) section for a more in-depth overview of `useQuery`.
 *
 * @example
 * ```jsx
 * import { gql, useQuery } from '@apollo/client';
 *
 * const GET_GREETING = gql`
 *   query GetGreeting($language: String!) {
 *     greeting(language: $language) {
 *       message
 *     }
 *   }
 * `;
 *
 * function Hello() {
 *   const { loading, error, data } = useQuery(GET_GREETING, {
 *     variables: { language: 'english' },
 *   });
 *   if (loading) return <p>Loading ...</p>;
 *   return <h1>Hello {data.greeting.message}!</h1>;
 * }
 * ```
 * @since 3.0.0
 * @param query - A GraphQL query document parsed into an AST by `gql`.
 * @param options - Options to control how the query is executed.
 * @returns Query result object
