Article: My teenage son Karl became _ after his father died. As a single parent, I tried to do my best to talk to him. But the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from classes and had six failing grades for the year. In this way he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked. One night I was at work when I got a phone call. A man introduced himself as the headmaster. "I want to talk to you about Karl's absences." Before he could say another word I choked up and said sadly, "I love my son. I've tried everything to get Karl to go back to school and nothing has worked. It's out of my hands." For a moment there was silence on the other end of the line. The headmaster seriously said, "Thank you for your time." and hung up. Karl's next report card showed a marked improvement in his grades. He was even on the list of the best students at school. In his fourth year, I attended a parent-teacher meeting. I noticed that his teachers were surprised at the way he had turned himself around. On our way home, he said, "Mum, remember that call from the headmaster last year?" I nodded. "That was me. I thought I'd play a joke but when I heard what you said, it really hit me how much I was hurting you. That's when I knew I had to make you proud. Question: Who was it that telephoned Karl's mother that day? Yes or no, is the answer "Karl himself"?
No

The SUV had landed upside down in five feet of water. A woman's leg could be seen swinging out the driver's side window. "I have a fear of water," Kenny said now. "I almost drowned when I was nine." Even so, he and Taron hurried down the 50-foot embankment into the muddy water. "I couldn't just leave her," he adds. The men waded out to the car and saw that the woman, Cheryl Allison, 61, was partially in water. Kenny tried unsuccessfully to open the door. Then he broke the window. But when he reached in to pull out Cheryl, he found she was trapped by the seat belt. "Run back to the truck and grab a box cutter ," Kenny yelled to Taron. Meanwhile, Kenny tried in vain to push the car onto its side to create an air pocket for Cheryl. That's when mechanic Marcell Porter approached the site. "I flipped into rescue mode," he said. When Taron returned, Kenny cut through the seat belt with the box cutter. He and Marcell tried to pull Cheryl out, but she wouldn't come out. Marcell broke the rear window with a rock, hoping to rescue her from the back. Then he saw that she was still strapped in by her shoulder belt. Marcell reached for the box cutter and cut the remaining strap in two. Kenny leaned in, grabbed Cheryl by the waist, and pulled her out feet first. Marcell grasped Cheryl's legs, and they managed to drag her lifeless body onto a rock. "Give her CPR!" Pamela yelled down to them. But the two men had no...
