Article: For the kids in Matt Marciano's sixth-grade social studies class, Thanks-giving is a time for great ideas. "We look at different foods that people eat around the world," says Marciano. "The lesson," he explains, "teaches students to admit that some people are unlucky. And it also gets them thinking about Thanksgiving, about their lives, and about their biggest homework of the year--to find a way they can change the world." Last year, 12-year-old Christian D. taught basic soccer skills to 63 kids with cancer. Christian's classmate Brianna used the money she had raised to buy 56 teddy bears. She donated them to a woman's shelter. Both students say the experience taught them something they'll never forget: When we give something to others, we're really giving thanks. And giving thanks feels good. "Helping the woman smile, if just for a day, made me feel like I could make a difference," Brianna says. "And it taught me that I should always be thankful for what I have." Brianna's happiness is something Jeffrey Froh knows about. Froh studies how gratitude affects a person's mind and attitudes. Those who are thankful are more likely to help others. Grateful people and kids in particular are healthier and happier than those who are not. "Grateful kids tend to be happier and more satisfied with their lives," Froh says. "Kids who give thanks are happier with school, their families and their friends. Grateful children also feel less envy toward others, are less likely to be depressed and even do better in school." "To experience gratitude," says Froh, "a couple of things have to happen. First you have to notice that there is goodness in your life. Then you have to admit that the reason for that goodness lies partially outside of yourself." Question: What's the main idea of the passage? Yes or no, is the answer "Expressing gratitude makes you happier and healthier."?
Yes

Article: If you really want to go green, here's good news: eating green is good for you. The very foods with a high carbon cost---meat, pork, dairy products, processed snacks---also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruits, whole grains, fish and lean meats like chicken---a diet that's eco- and waistline-friendly. Eating green can be healthier and beneficial to the climate. It may be hard to believe that a meal at McDonald's produces more carbon than your trip to a far away place. More than 37% of the world's land is used for agriculture, much of which was once forested. Deforestation is a major source of carbon. The fertilizer and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate. The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent amount of grains, fruits or vegetables. What's more, the majority of cattle in the U.S. are fed on grain and loads of it---670 million tons in 2002---and the fertilizer used to feed that creates separate environmental problems. Focus on eating lower on the food chain, with more plants and fruits and less meat and dairy. It's simple. We can change today what goes into our bodies for the health of our planet and ourselves. Question: In the author's opinion, the most efficient way to reduce carbon is to _ . Yes or no, is the answer "eat more vegetables than meat"?
No

Article: What a Scientist Is Like If you were asked to imagine a scientist, what image would come to your mind? The common idea that most kids from kindergarten through college have of a scientist is a man wearing a white lab coat with messy hair, big glasses, and several glass cups of mysterious color1ful liquids giving off clouds of smoke. As for adults, the majority view scientists as strange people who spend 100 hours a week slaving away in a lonely laboratory. However, the reality is quite different. Recently I've had a chance to take part in a scientific experience far from my laboratory and into Costa Rica. It supports a huge amount of wildlife due to its geographical placement between North and South America. It is home to more than 500,000 species ,which represents nearly 4% of the total species worldwide! First we worked alongside conservationists to preserve wildlife at a leatherback turtle ( )rescue center. We helped the volunteers preserve turtle populations by removing rubbish from the shoreline to create a safe environment for turtle eggs to come out. After that we stayed at Mount Arenal where we studied seismic activity relating to earthquakes. During our stay at Arenal, we rode over the mountainous areas and took a long walk through the rainforest. After reaching the top, we went down and through waterfalls to the beautiful valley below! On the last day we got a hands-on introduction to rocket science where we learned about new rocket technology that will be used on the international space station. During my Costa Rica experience, I know that being a scientist doesn't mean working in a lab all day and night. A scientist is one who loves learning and getting a better understanding of the world from helping preserve wild-life, learning about earthquakes or inventing rockets. I think that schools should really stress that science is so much more than wearing a lab coat and mixing chemicals. Kids need to be aware of the excitement and adventures science can bring! Question: What does the author learn about science from his experience? Yes or no, is the answer "Science is more than working in a lab."?
No
