Article: One cold day in winter, my wife and I were walking back home from the grocery store as usual when we suddenly decided to walk into a coffee shop. My wife ordered a coffee at the counter. Just then, I saw a young woman in her thirties helping with a rather weak Mexican woman into the shop. Maybe it was the gentleness of their difficult experiences or an unclear familiarity with the situation that drew my full attention. I immediately had a strong wish to do something for them. Unfortunately, before I could think of anything reasonable to say, they left the coffee shop without ordering anything! When my wife returned, I told her about the two women and said, "I missed the chance to do something for them." Strangely enough, though, they came back into the same coffee shop five minutes later. Unbelievable! "This is my chance," I thought out loud as my wife shared some creative possibilities. The two women ordered, took their place card and left the counter. After quickly finishing our coffee, we walked up to the counter and asked the smiling cashier , "What is your most popular dessert ?" Chocolate Cake," she answered. With a childlike feeling of happiness, my wife made an unusual order. "Can I buy a chocolate cake for the two women who were here just before us? But don't tell them it is from us. Just give them this card," she said while taking out a smile card. The cashier couldn't believe it. " Do you do this all the time?" she asked. " Not all the time, but just whenever the heart calls for it," I answered with a natural smile. We, my wife and I, are people of middle income . That night, we had planned to have our once-in-a-while dinner at a restaurant. But walking out of that coffee shop, both of us stood upright and said, "Let's eat at home today." It's more filling to give a chocolate cake than to eat it. Question: Why did the author and his wife decide to eat at home? Yes or no, is the answer "They were full of happiness from giving."?
No

Article: The other day when I was passing a clothing store, I fell in love with a skirt. I knew it would suit me best at first sight. But when I looked at the price tag , I knew I had to give it up. The love for beautiful clothes has been planted in my heart the day when I was born to be a woman. Several years ago I read an article in a magazine. The article stated that when a woman is at her best time, she is usually poor or tasteless, so she can't get the right clothes; when she can afford to buy the clothes she likes, she often finds that they do not suit her anymore. On the way home, I was quite disturbed by such thoughts. It was just a pity, like many other pities. I thought to myself this way. But when I was about to enter the building where I was living, I saw the big mirror placed in the entrance. I saw a girl in it who was in cheap but cleanly washed sweater and jeans. _ was rather young, healthy and energetic. For quite a while I was touched by what I had seen in the mirror. Then I almost forgot the tale: A person without shoes cried until he saw a man without feet. Being young without good clothes is like the person without shoes. I should have felt grateful that I haven't lost my feet. Question: We can learn from the text that the author considered her love for beautiful clothes as _ . Yes or no, is the answer "natural"?
Yes

Article: The future of agriculture must achieve several goals at the same time. First, it now appears that we will have to double world food production in the next 40 years due to population growth, increasing meat consumption and pressure from biofuels . We will also have to reduce the environmental impacts from our farming practices, which have caused widespread damage to soils, ecosystems, waters and even the atmosphere. In fact, agriculture's impacts are as bad as climate change as an environmental concern. Besides, we will have to improve food security for the world's poor. While the Green Revolution of the 1960s made it possible to feed hundreds of millions more people than in earlier eras, the number of the under-nourished in the world has started to rise again. Finally, we will have to increase the recovering ability of agriculture from shocks. Today, our high-efficiency, globalized world has many benefits, but it is vulnerable to destruction, whether from droughts, diseases or sudden price rises. We must start building better food systems to better keep us away from future shocks. Currently, there are two models of agriculture: local and organic agriculture vs. globalized and industrialized agriculture. Each has been strongly supported and severely criticized, but neither of these models, standing alone, can fully meet our needs. Organic agriculture teaches us important lessons about soils, nutrition and pest management. Unfortunately, organic food provides less than 1% of the world's calories, mostly to the wealthy. It is hard to imagine organic farming developing to feed 9 billion. Globalized and industrialized agriculture has benefits of high output and low labor demands. Without it, billions of people would have starved. However, it has come with enormous environmental and social costs, which cannot be sustained. Rather than voting for just one solution, we need a third way to solve the crisis. Let's take ideas from both sides, creating new, hybrid solutions that increase production, save resources... Question: We can learn from the passage that _ . Yes or no, is the answer "the writer is quite optimistic about future agriculture"?
Yes
