The verified answer to “Books and Authors question: Which statement about Cosmos is accurate?” is It is a English-language work by Carl Sagan, first published in 1980., option B. The source-backed, question-specific record explains: Cosmos is correctly associated with Carl Sagan. The work’s first publication is conventionally dated to 1980, and its original language is English. These three details—title, author, and language—form the decisive bibliographical combination required here. Carl Sagan, a major American literary figure, is also associated with Pale Blue Dot; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (It is a English-language work by Jared Diamond, first published in 1997.; It is a French-language work by Simone de Beauvoir, first published in 1949.; It is a German-language work by Sigmund Freud, first published in 1899.) 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 1980 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 “Cosmos — Carl Sagan — English — 1980,” and connect it with Pale Blue Dot 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. Option B gives It is a English-language work by Carl Sagan, first published in 1980.
