Article: We live in a culture that sends out very mixed messages about mistakes: We're told we learn by making them, but we work hard to avoid them. So the result is that most of us know that we are going to make mistakes, but deep down, we feel we shouldn't. Experiments with schoolchildren who did well on a given test show that those who were praised for being smart and then offered a more challenging or less challenging task afterward usually chose the easier one. On the other hand, children praised for trying hard-- rather than being smart--far more often selected the more difficult task. If we try hard to avoid mistakes, we aren't open to getting the information we need in order to do better. In a writing study, experiments showed that those who are so scared to make mistakes perform worse in writing tasks than those who aren't as worried about being perfect. They fear receiving any kind of negative feedback, so they don't learn where they went wrong and how to get better. We don't just learn more when we're open to mistakes, we learn deeper. Research tells us that if we're only concerned about getting the right answer, we don't always learn the underlying concepts that help us truly understand whatever we're trying to figure out. Mistakes need to be seen not as a failure to learn, but as a guide to what still needs to be learned. As Thomas Edison said, "I am not discouraged, because every abandoned wrong attempt is another step forward." Furthermore, we often make mistakes because we try new things--we wander away from accepted paths. Teflon, penicillin--these are examples of great discoveries made by mistake. Take a page from Albert Einstein, who said, "Anyone who has never made a mistake has never tried anything new. "

Article: Catherine and I were on our way to our nephew's birthday party one rainy Saturday morning, driving along what some people call moose alley. It was early, there were few other cars on the road and we were looking forward to a good day with the family. Suddenly, a moose rushed across our path. Fortunately, a quick swerve to the other lane prevented a full impact, with only a small collision on the right side of our car ripping off the mirror and knocking the moose to the pavement. By the time I stopped and looked back in my rear view mirror, the moose was getting up. It ran into the bush. Shaken but unharmed, we both looked at each other shocked by what had happened. We knew that moose accidents had claimed many lives throughout the years, and that we had been very fortunate to escape with no personal injury or worse. After a quick check of our vehicle, we drove off. Even though the moose accident lasted just a few seconds, we still remember it to this day. Why? We had often talked about the frailty of life, the here today and gone tomorrow potential we all face, but it had never felt so real. And it wasn't that we hadn't had friends, relatives and colleagues die before, it was that this experience was much more personal. In a matter of seconds, lives can easily change. The effect of that one near miss with death has been positive, and made us appreciate life. Each one of us has only a limited time on this Earth; no one can predict when your time will end. We should give thanks for each day, to see the sun rise again, and to know that you can accomplish and assist others to appreciate their life if they are caught in the "poor-me" syndrome .
Question: What did the accident teach the author?
Options: (A) Being open to unexpected turns in life is important. (B) Life is long if you know how to use it. (C) Life is measured by thoughts and actions, not by time. (D) Life is unpredictable, so we should treasure every moment.
