Along the way , important information was asked and written for admission to the hopsital ... the medical personnel were really nice , they even showed my other son how the sirens work . We arrived at the hospital before 4:30 pm , and I could only say thank you to them as my mind was still whirling a little .

Answer: None of the above choices .They are concerned about the sirens .They are concerned about their son .They did n't get enough sleep .
