Q: I'm taking a test and have to guess the right answer to the question after the article. Article: ScienceDaily (July 5, 2009) -- Researchers from the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb , which enables it to harvest 16 times the amount of water collected by other plants in the Negev Desert. This is the first example of a self-irrigating plant worldwide. The desert rhubarb grows in the mountains of Israel's Negev desert, where average rainfall is particularly low (75 mm per year). Unlike most of the other desert plant species, which have small leaves so as to reduce water loss, this plant is unique in that its leaves are particularly large; each plant's rosette of one to four leaves reaches a total diameter of up to one meter. Prof. Simcha Lev-Yadun, Prof. Gidi Ne'eman and Prof. Gadi Katzir came across this unique plant while studying the field area with students of the Department of Science Education-Biology of the University of Haifa-Oranim, and noticed that its waxy leaves are unusually large. They observed an exceptionally ridged structure on each leaf. The scientists explained that these deep and wide depressions in the leaves create a "channeling" mountain-like system by which the rain water is channeled toward the ground surrounding the plant's deep root. Other desert plants simply absorb the rain water that goes through the ground in its immediate surroundings. The desert rhubarb is able to harvest quantities of water that are 16 times the amount of water harvested by the small-leafed plants of the Negev desert region. When the research team watered the plant artificially, they observed how the water flows along the course of the leave's depressions to the ground surrounding the plant's single root and then goes through the ground to a depth of 10 cm or more. Under the experimental conditions, water goes through the ground only as deep as 1 cm. "We know of no other plant in the deserts of the world that functions in this manner," the researchers concluded. Question: What is the best title for the passage? Options: A: How plants' "self-irrigating" mechanism works B: How plants growing in the desert survive C: The desert plants growing in the Negev Desert D: The world's first "self-watering" plant discovered
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: William H. Gates is chairperson and chief software architect of Microsoft Corporation.the worldwide leader in software services and internet technologies for personal and business computing.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: It had been a very disheartening day. The doctors had given us the worst of news. Our daughter, who had just completed her first brain surgery to remove a tumor and was going through radiation treatment, was now officially given a two percent chance of survival as this type of cancer had no cure. My wife and I decided to take our daughter to lunch before continuing our afternoon conversation. We went to a local restaurant where we sat in silence waiting for the waitress. I noticed a very elderly couple sitting a few booths away, who were also in silence and did not speak a word. I couldn't help but wonder what challenges they had faced in their life and if they ever faced such terrible news about a child of theirs. We eventually ordered our lunch and still sitting in silence we ate what we could. At some point I became intrigued by the old couple. I thought to myself that they hadn't yet spoken to each other and I wondered if it was the peace they were enjoying or the food or maybe both. However, at some point I lost interest and put my focus back on my lunch. Molly was still talking away and enjoying her meal. Her mom and I both listened and tried to be happy in her presence but it wasn't going very well. All of a sudden I saw a hand come out of nowhere. It was huge and I could tell that it had been afflicted with arthritis . I couldn't take my eyes off that hand. It landed on my daughter's tiny six-year-old hand and as it did I looked up; it was the old woman who had been sitting with the old man in silence eating their lunch. I looked into her eyes and she spoke, but not to me. She looked at my daughter and simply whispered, "If I could do more for you I would..." and then she smiled and moved away to join her husband, who had moved towards the door. "Look, a whole dollar," Molly spoke with excitement as she discovered a crumpled one dollar bill left behind by the old lady. I looked up to thank her, but she was gone. I sat stunned, not sure what had just happened and... Question: By saying "If I could do more for you I would...", the old woman means _ . Options: A: she had the ability to cure the disease of Molly B: she had the responsibility for the safety of Molly C: she was an old friend of the author and can lend some money to them D: she would like to help Molly as much as possible
