In a Copyright Ruling, the Legacy of the Betamax
Identify the 2013 Supreme Court case involving a Thai math student receiving textbooks from abroad, which legal analysts compared to the landmark 1984 Sony Betamax ruling that established the legal groundwork for the video rental industry (such as Blockbuster and Redbox). Provide the full name of the student defendant and the specific copyright doctrine upheld in this decision. Furthermore, quote the famous metaphor used by MPAA head Jack Valenti during the 1980s to describe the threat the VCR posed to the American film producer, and name the specific Massachusetts-based startup mentioned in 2013 analyses as a 'secondhand market for digital content' that was facing a lawsuit from Capitol Records despite this legal precedent.
Answer length: 200-300 words.

- Target Case: Kirtsaeng v. John Wiley & Sons
- Logic Validation: Intersects the 2013 textbook import case with the 1984 Betamax video rental case precedent.
- Student Name: Supap Kirtsaeng (or Kirtsaeng)
- Legal Doctrine: The 'First Sale' doctrine (or Right of First Sale)
- Jack Valenti Quote: 'The VCR is to the American film producer and the American public as the Boston strangler is to the woman home alone.'
- Digital Startup: ReDigi
The question requires Deep reasoning to identify a specific 2013 Supreme Court case (Kirtsaeng) based on its description and its analogical relationship to the 1984 Betamax case found in the source text. It requires Wide aggregation to retrieve specific unconnected details: the student's name, the legal doctrine ('First Sale'), a specific historical quote by Jack Valenti regarding VCRs, and the name of a specific digital startup (ReDigi) mentioned in the context of these legal arguments.
Judgment
Both agents correctly identified all the entities requested: the case (Kirtsaeng v. John Wiley & Sons), the student (Supap Kirtsaeng), the doctrine (First Sale), the Valenti quote, and the startup (ReDigi). Agent A is preferred primarily due to the quality of its citations and narrative flow. Agent A cites specific newspaper articles (NYT, Boston Globe) and the Supreme Court reporter, whereas Agent B cites Wikipedia and generic legal blogs. Agent A also provides slightly more context regarding the student's background (Cornell Ph.D.) which enhances the answer's depth without violating the word count constraint.
