[EX Q]: Article: When you make a mistake, big or small, cherish it like it's the most precious thing in the world, because in some ways, it is. Most of us feel bad when we make mistakes, beat ourselves up about it, feel like failures, get mad at ourselves. And that's only natural. Most of us have been taught from a young age that mistakes are bad, and we should try to avoid mistakes. We've been scolded when we make mistakes--at home, school and work. Maybe not always, but probably enough times to make feeling bad about mistakes an unconscious reaction. Yet without mistakes, we could not learn or grow. If you think about it that way, mistakes should be cherished and celebrated for being one of the most amazing things in the world. They make learning possible; they make growth and improvement possible. By trial and error--trying things, making mistakes, and learning from those mistakes--we have figured out how to make electric light, to paint the ceiling of the Sistine Chapel, to fly. Mistakes make walking possible for the smallest _ , make speech possible, and make works of genius possible. Think about how we learn:We don't just consume information about something and instantly know it or know how to do it. You don't just read about painting,or writing,or computer programming,or baking, or playing the piano, and know how to do them right away. Instead, you get information about something, from reading or from another person or from observing usually...then you construct a model in your mind...then you test it out by trying it in the real world...then you make mistakes...then you revise the model based on the results of your real world experimentation...and repeat, making mistakes, learning from those mistakes, until you've pretty much learned how to do something. That's how we learn as babies and toddlers, and how we learn as adults. Mistakes are how we learn to do something new--because if you succeed at something, it's probably something you already knew how to do. You haven't really grown much from that success--at most it's the last step on your journey, not the whole journey. Most of the journey is made up of mistakes, if it's a good journey. So if you value learning,if you value growing and improving,then you should value mistakes. They are amazing things that make a world of brilliance possible.
Question: Why do most of us feel bad about making mistakes?
Options: (A) Because mistakes make us suffer a lot. (B) Because it's a natural part in our life. (C) Because we've been taught so from a young age. (D) Because mistakes have ruined many people's careers.

[EX Q]: Article: Pierre is a 25-year-old penguin at the California Academy of Sciences.Due to his old age,he was going bald,which made him feel too cold to swim in the pool.Therefore,biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool. Unlike marine mammals,which have a layer of blubber to keep them warm,penguins depend on their waterproof feathers.Without them,Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water. "He was cold:he would shake,"said Pam Schaller,a senior biologist.Schaller first tried a heat lamp to keep Pierre warm.Then she got another idea:if wetsuits keep humans warm in the cold Pacific,why not make one for Pierre? Schaller designed the suit,which covered Pierre's body and had small openings for his flippers. "I would walk behind him and look at where there were any gaps.and cut and refit until it looked like it was extremely suitable."she said. One concern was that the other penguins would reject Pierre in his new suit,but in fact,they accepted his new look.He swam freely and got along with others well,although he was the only penguin with a black stomach. Schaller couldn't say for sure whether the wetsuit allowed Pierre to recover his fine feathers,but" certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable". Pierre will take off his suit after his new feathers grow back.
