Books and Authors question: In a comparison beginning with Capital, Volume I, which of the following book–author pairs is incorrectly matched?

The source-backed, question-specific record explains: Capital, Volume I is correctly associated with Karl Marx. These three details—title, author, and language—form the decisive bibliographical combination required here. The distractor set (The Republic — Plato; An Era of Darkness — Shashi Tharoor; On the Origin of Species — Charles Darwin) 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. Revision takeaway: remember the compact chain “Capital, Volume I — Karl Marx — German — 1867,” and connect it with The Communist Manifesto 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 A gives Capital, Volume I — Plato and satisfies the wording of the question. The remaining choices—The Republic — Plato, An Era of Darkness — Shashi Tharoor and On the Origin of Species — Charles Darwin—do not satisfy the complete requirement. Depending on the stem, a distractor may name a real writer but attach the wrong title, use a related work by another author, reverse a correct association, or present a correct pair when the question specifically asks for the incorrect match. The reliable checking method is to identify the reference title first, recall or verify its credited author, and then read qualifiers such as “both works,” “original language,”.
