Q: Read the following article and answer the question. Article: In South America, the rich soil of the Amazon River basin in Brazil is known as "black gold". Scientists found that the secret of this rich soil was charcoal . Local people made it from animal bones and tree branches. They mixed the charcoal with the soil about 1.500 years ago. Now, scientists in the United States have done a modern demonstration. They say charcoal fertilization offers a revolutionary way to improve soil quality for hundreds or even thousands of years. Mingxin Guo and his team at Delavare State University heated tree leaves, corn stalks , small pieces of wood and poultry waste into "biochar" . They reported their findings at a recent meeting of the American Chemical Society in New Orleans. Biochar could be good news for farmers with poor soil and hungry populations to feed. Professor Guo says it could even help against global warming. Intensive  farming and overuse of chemical fertilizer give out carbon dioxide into the atmosphere. Biochar does the opposite, he says. It traps carbon in the ground. The researchers planted winter wheat in containers of soil in a greenhouse -- some with biochar, some without. Professor Guo says the wheat grows much better in the pots with biochar. The soil was added two percent charcoal to. But he says even a one percent treatment will increase productivity. The results demonstrated that biochar can increase organic matter in soil. Loss of nutrients in soil is an increasing problem worldwide as farmers try to grow more food for growing populations. Next, the team will carry out a five-year study of biochar with spinach , green peppers and tomatoes. Mingxin Guo says he learns about the "black gold" in Brazil from a magazine story. He explains that it was discovered in the jungle, in the area where waters flow to the Amazon, in the 1960's. But it was not until recent years that scientists began to bring public attention to it. Question: According to the passage, which of the following statements is TRUE? Answer:
Answer: The researchers will go on proving their theory.

Q: Read the following article and answer the question. Article: My divorce was now final and I needed to find a new home for me and my six-year-old son, Dash. A few days earlier I'd seen an ad. I was willing to try anything, so I contacted the owner, a woman named Camille. When she e-mailed me back I discovered she wasn't renting a house at all. She was renting the attic   apartment. I left her a message calling off our meeting. But Camille called me back and insisted I come over. So here I was. I pulled the car to a stop and looked up at the tiny cottage. The house was small as it was. The attic window looked too tiny to let much light in. We couldn't live in a dark, depressing place. I could make do with almost anything. But Dash needs a good home, a place he really feels safe. No sense in wasting her time or mine. I knocked. The woman who opened the door was small and bright-eyed. She was much older than I'd guessed, but I could see she had the energy of someone half her age. She looked so sympathetic that I found myself wanting to keep talking to her."We have to leave our home,"I explained."My marriage ended. I only have a few days to find something else, but I want it to be right." Camille nodded."You're a good mother. You never know the miracles that await youaround the corner."Camille walked me to the door and wished me well. I got back in the car and snapped out of it. I drove off slowly, hoping to make the feeling last. I turned down a side street I didn't recognize. I glanced out of the side window. Just up ahead was a cottage with a sign out in front: for rent. I pulled over. I found the owners had just bought the house themselves and were decorating it, hoping to find the perfect renters. They took me on a tour of the house that was like a copy of my list: a big bedroom for Dash, a backyard with trees, and a great school nearby. The house was meant for us! Camille was right. Miracles await us, just around the corner. Question: Why must the author find a good place? Answer:
