Q: Article: The rain had continued for a week and the flood had created a big river which were running by Nancy Brown's farm. As she tried to gather her cows to a higher ground, she slipped and hit her head on a fallen tree trunk. The fall made her unconscious for a moment or two. When she came to, Lizzie, one of her oldest and favorite cows, was licking her face. At that time, the water level on the farm was still rising. Nancy gathered all her strength to get up and began walking slowly with Lizzie. The rain had become much heavier, and the water in the field was now waist high. Nancy's pace got slower and slower because she felt a great pain in her head. Finally, all she could do was to throw her arm around Lizzie's neck and try to hang on. About 20 minutes later, Lizzie managed to pull herself and Nancy out of the rising water and onto a bit of high land, which seemed like a small island in the middle of a lake of white water. Even though it was about noon, the sky was so dark and the rain and lightning was so bad that it took rescuers more than two hours to discover Nancy. A man from a helicopter lowered a rope, but Nancy couldn't catch it. A moment later, two men landed on the small island from a ladder in the helicopter. They raised her into the helicopter and took her to the school gym, where the Red Cross had set up an emergency shelter. When the flood disappeared two days later, Nancy immediately went back to the "island." Lizzie was gone. She was one of 19 cows that Nancy had lost in the flood. "I owe my life to her," said Nancy with tears.
