The verified answer to “Books and Authors question: The Wealth of Nations first appeared in 1776. The source-backed, question-specific record explains: The Wealth of Nations is correctly associated with Adam Smith. The work’s first publication is conventionally dated to 1776, and its original language is English. These three details—title, author, and language—form the decisive bibliographical combination required here. Adam Smith, a major Scottish literary figure, is also associated with The Theory of Moral Sentiments; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (John Maynard Keynes; English; Plato; Ancient Greek; Yuval Noah Harari; Hebrew) must therefore be tested as complete statements: one true fragment cannot make an entire option correct. A candidate should first lock the title to its writer, then check the language, and finally use 1776 as a chronological cross-check. A common examination trap is to confuse an author’s nationality with the language of composition, or a translation date with first publication. Another is to treat a well-known adaptation or later edition as the original work. Revision takeaway: remember the compact chain “The Wealth of Nations — Adam Smith — English — 1776,” and connect it with The Theory of Moral Sentiments for stronger recall. This evidence establishes the bibliographic relationship required in this Books and Authors item. A correct solution must preserve the exact title, author, publication context, language, award or comparison requested by the stem. Similar periods, genres or national traditions do not make two book–author pairs interchangeable. Option D gives Adam Smith; English and satisfies the wording of the question. The remaining choices—John Maynard Keynes; English, Plato; Ancient Greek and Yuval Noah Harari; Hebrew—do not satisfy the complete requirement.
