The verified answer to “Books and Authors question: With The Republic as the reference work, which book–author pair is correctly matched?” is The Republic — Plato, option B. The source-backed, question-specific record explains: The Republic is correctly associated with Plato. The work’s first publication is conventionally dated to 375 BCE (traditional dating), and its original language is Ancient Greek. These three details—title, author, and language—form the decisive bibliographical combination required here. Plato, a major ancient Greek literary figure, is also associated with Symposium; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (The Shadow Lines — William Dalrymple; The Last Mughal — Adam Smith; The Wealth of Nations — Amitav Ghosh) must therefore be tested as complete statements: one true fragment cannot make an entire option correct. 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 Republic — Plato — Ancient Greek — 375 BCE (traditional dating),” and connect it with Symposium 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 B gives The Republic — Plato and satisfies the wording of the question. The remaining choices—The Shadow Lines — William Dalrymple, The Last Mughal — Adam Smith and The Wealth of Nations — Amitav Ghosh—do not satisfy the complete requirement.
