Hey, guys! I'm having trouble understanding why B is incorrect. My reasoning for selecting B was that if the diseased male grouse were treated with antibiotics their sacs would show that they were infected and this strengthened the hypothesis because the females would see this on their sacs and would not select them because they were unhealthy. It looks like I've made some assumptions somewhere or am I even on the right path with my logic? I read two explanations that aren't close to mine.
