The verified answer to “Books and Authors question: With The Second Sex as the reference work, which book–author pair is correctly matched?” is The Second Sex — Simone de Beauvoir, option B. The source-backed, question-specific record explains: The Second Sex is correctly associated with Simone de Beauvoir. The work’s first publication is conventionally dated to 1949, and its original language is French. These three details—title, author, and language—form the decisive bibliographical combination required here. Simone de Beauvoir, a major French literary figure, is also associated with The Ethics of Ambiguity; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (The Prince — Jean-Jacques Rousseau; The Social Contract — Carl Sagan; Cosmos — Niccolò Machiavelli) 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 Second Sex — Simone de Beauvoir — French — 1949,” and connect it with The Ethics of Ambiguity 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 Second Sex — Simone de Beauvoir and satisfies the wording of the question. The remaining choices—The Prince — Jean-Jacques Rousseau, The Social Contract — Carl Sagan and Cosmos — Niccolò Machiavelli—do not satisfy the complete requirement.
