Show answer & explanation

Correct answer: A

Answer: S2 = "You might assume that birds sing because they are happy." S3 = "Birds also sing to find a healthy mate."

Explanation:

  • The opening question asks why birds sing; the sentence "You might assume that birds sing because they are happy." acknowledges a likely assumption and so fits directly after the question.

  • The next sentence, "Birds also sing to find a healthy mate," gives a purpose (mate attraction) that logically leads to the final sentence: "The length and complexity of the song give information about the health of the bird."

  • Other orders fail because a territorial warning does not connect to the concluding point about health, or because the hypothetical assumption would be placed after an asserted fact, which breaks the logical flow.
