A young woman went to her mother and told her how hard life was. She was tired of struggling and fighting and wanted to give up. So, her mother took her to the kitchen. She filled three pots with water and placed each on a high fire. Soon the pots came to boil. In the first she placed carrots, in the second she placed eggs, and in the last she placed coffee beans. She let them sit and boil, without saying a word. In about twenty minutes she turned off the burners. She fished the carrots out, pulled the eggs out and then poured the coffee into three different bowls. Turning to her daughter, she asked, "Tell me what you see." "Carrots, eggs, and coffee," she replied. Her mother brought her closer and asked her to feel the carrots. She noted that they were soft. The mother then asked the daughter to take an egg and break it. After pulling off the shell, she observed the hard boiled egg. Finally, the daughter was asked to drink the coffee. She smiled as she tasted its rich fragrance. The daughter then asked, "What does it mean, mother?" Her mother explained that each of these objects had faced the same disaster but reacted differently. The carrot went in strong, and hard. However, after being subject to the boiling water, it softened and became weak. The egg had been fragile, but after sitting through the boiling water, its inside became hardened. The coffee beans were unique, however; after they had been in the boiling water, they had changed the water. "Which are you?" she asked her daughter. "When misfortune or change knocks on your door, how do you respond? Are you a carrot, an egg or a coffee bean?" "Are you the carrot that seems strong, but with change and difficulty will you wilt and become soft and lose your strength? Are you the egg that starts with a malleable , heart, but changes with the heat? When faced with a death, a break-up, a financial hardship or other trial, do you become hardened and stiff? The coffee bean actually changes the hot water, the very circumstance that brings the... What can serve as the best title of this passage? A) Boost Yourself to Another Level B) A Young Woman and Her Mother C) A Carrot, an Egg or a Coffee Bean D) Survival of the Fittest

When Jeff Sparkman draws his cartoon superheroes with colored pencils, he often has to ask other people to tell him what color his masked men turned out to be because he's color-blind. Now, a new smart phone application (app) can help him figure out what colors he's using and how the picture looks to most everyone else. The DanKam app, available for iPhone and Android for $2.99, is an application that turns the vague colors that one percent of the population with color-blindness sees into the "true" colors as everyone else sees them. In America, an estimated 32 million color-blind Americans--95% are males--can soon have their life improved. "DanKam takes the stream of data coming in through the phone's camera and changes the colors slightly so they fall within the range that people who are color-blind see,"developer Dan Kaminsky told CNET. He came up with the idea after watching the 2009 film Star Trek with a color-blind friend. It was then that he got to know more about colorblindness like its varying types and degrees. A vast majority, for instance, have trouble seeing red or green due to a genetic defect . Blue-yellow colorblindness, however, is rarer and develops later in life because of aging, illness or head injuries, etc. He started experimenting with one of the most common representations of points in the RGB color model. What the DanKam app attempts to do is to clean up the color space of the image or video signal so that colors can be _ to those suffering from viewing problems. "You can adjust the app to fit your needs. There is a range and not everyone who is color-blind sees things the same." Says Kaminsky. Sparkman, a copy editor at CNET, tried out the app and was pleased with the results. "It would be useful for dressing for a job interview," he said. But using it for his art is "the most practical application." It worked well on LED and other lights on electronic gadgets, which means Sparkman can now identify the power light on his computer display as green. How does DanKam's app work? A) It puts LED and other lights on electronic gadgets. B) It shows common representations of points in the RGB color model C) It checks color-blind people's types of degrees of colorblindness. D) It changes the colors so that color-blind people can see them.

*Question*
Europe's deadly outbreak of a rare form of E. coli bacteria has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick? Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways. Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines of humans and many animals. Most kinds of E. coli are harmless but some can make people sick. The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers. Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team. MOON KIM: "We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample." The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit. Moon Kim says the team hopes the system will be available before long. MOON KIM: "We are targeting for development in commercial plants for the next several years." The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface. What can be inferred from the text? A) The scanner needs to be improved. B) The scanner will be available in the next several years. C) Moon Kim is unwilling to develop the scanner. D) The scanner is connected to a sorting machine.
