Emergency<br>The sermon started, and everyone sat to hear it. During the sermon, a man fell asleep. His wife shook him, but he did not wake up. People in the church came to check on him, but he was unresponsive. The paramedics took him to the hospital, where he later died.
He was not unresponsive before he fell asleep.
Before falling asleep, the man and everyone else sat to hear a sermon. It makes no sense to say that he was unresponsive before falling asleep. The model doesn't understand common sense in this case.
