Explanation:

To determine the effective text structure, analyze each option:

• Option 1: The passage doesn't focus on expressing multiple scientists' views.
• Option 2: There's no problem - solution with claims and counterclaims.
• Option 3: The passage answers "why" questions (e.g., why are yawns contagious - related, why do most animals yawn) and supports these with reasons (like brain stem similarity) and evidence (examples of animals that yawn, expert quotes). This matches a why/because structure.
• Option 4: The passage uses information from a few experts, not a variety of sources.

Answer:

It establishes a why/because relationship that is supported with reasons and evidence.
