[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: The percentage of districts that require elementary schools to teach physical education increased, to 93% last year from 83% in 2000. But just 4% of elementary schools, 8% of middle schools and 2% of high schools provided physical education each school day, as is recommended by the disease control agency. One-fifth of schools did not require physical education at all. In 2004, Congress passed a law requiring each school district to develop a "wellness policy" to promote the students' health by setting goals for nutrition education and physical activity. Those policies are just now taking effect, and some school administrators predict that the next survey will show more marked improvements. Some schools have set out to place health education on the same requirement with academics. In Los Angeles County, Sepulveda Middle School has banned soft drinks and eliminated unhealthy snacks from the school store. Salad, fruit and yogurt are always available in the cafeteria, said Patricia J. Pelletier, the principal. Nearly an hour of physical education is required daily, the school offers after-hours training in distance running, and it has started a class on healthy cooking for parents. "If kids are healthy and have healthy lifestyles, they're going to be better students," Ms Pelletier said. "They're going to be in school, and they're going to be connected with the teachers in a better way." The survey found that nearly two-thirds of schools prohibited tobacco use at all places, including at off-campus functions, up from 46% in 2000. Another finding was that the proportion of states that require middle schools to teach human sexuality grew, to 59% from 46%. The report found a variety of indications of healthier cooking in school cafeterias. 55% reported that they had removed the skin from poultry before cooking, up from 40%, and 46% now use low-fat cheeses, up from 31%. But 12% of elementary schools, 19% of middle schools and 24% of high schools offer students brand-name fast food from businesses like Pizza Hut and Taco Bell.
Question: What is the best title for this passage?
Options: (A) How to change children's eating habits (B) Improve students' physical health by developing their nutrition education (C) Only a little percentage of students are taught physical education (D) Healthy habits should be taught in schools
