Answer

Brief Explanations:

  • Option A: Text 2 says robins use song for mate selection AND territory, so modern ornithologists don't "highlight only" mate selection. Eliminate A.
  • Option B: Text 1 focuses on song's role in territoriality, not "historical significance", and Text 2 focuses on its complexity, not "modern applications". Eliminate B.
  • Option C: Text 1 emphasizes song for territorial defense (a simple marker), Text 2 shows song is multifaceted (territory, mate, rivals, context - dependent). This matches.
  • Option D: Text 2 says new tech uncovered more complexities, so modern ornithologists don't say "no additional complexities". Eliminate D.

Answer:

C. John Legg (Text 1) believes that the robin's song is a simple territorial marker, whereas modern ornithologists (Text 2) also view it as a multifaceted communication tool.
