Read the excerpt from "Home Front Diary." I was helping Mom clean the dishes from Sunday dinner, and Dad had the radio tuned in to "The Great Inspector" as usual. Midway through the program the announcer broke in with the news that Pearl Harbor had been attacked, and I felt my heart sink to my shoes. It was like time stopped as I stood there staring at the soap bubbles. I don't even remember how the rest of the cleanup got finished.

Which word best describes the mood of this excerpt?

anticipation
disbelief
joy
fear
