[EX Q]: Article: Once upon a time the colors of the world started to quarrel. Green said, "Clearly I am the most important. I am the sign of life and hope. I was chosen for grass, trees and leaves. Look over the countryside and you will see that I am in the majority." Blue interrupted, "You only think about the earth, but consider the sky and the sea. It is the water that is the basis of life." Yellow chuckled . "The sun is yellow, as well as the moon and the stars. Every time you look at a sunflower, the whole world starts to smile." Red could bear it no longer. "I am the ruler of all of you. I am blood-life's blood! I am the color of danger and bravery. I bring fire into the blood. I am the color of passion and love." Purple stood at his full height. "I am the color of royalty and power. I am the sign of authority and wisdom. People do not question me! They listen and obey." Finally Indigo spoke with determination, "Think of me and I am the color of silence. I represent thought and reflection. You need me for balance and contrast , for prayer and inner peace." The colors went on boasting , each showing off his or her own advantages. Suddenlythere came a flash of bright lightening. Thunder rolled and boomed. Rain started to pour down. The colors were scared to death. In the midst of the quarrelling, rain began to speak, "You foolish colors. Don't you know that you were each made for a special purpose, unique and different? Join hands with one another and come to me." Doing as they were told, the colors united and joined hands. From then on, when it rains, colors will stretch across the sky in a great bow of color. Whenever a rainbow appears in the sky, let us remember to appreciate one another.

[EX Q]: Article: BIG DAY: New Canadian citizen Pemelika Fiaui poses with his son Tyler, 4, outside of The Playhouse on Tuesday. The ceremony marked the end of a five-year journey for Pemelika Fiaui of Western Samoa. Fiaui, a 6'4", 240-pound member of local rugby team Black Spruce, said the day was emotional. "I was really happy to get my citizenship today; it was a long process," he said. "I couldn't have done this without the support of my wife, my in-laws and my two kids, who have been so supportive of me." Fiaui, a firefighter by trade, arrived in New Brunswick in 2003 and found work with the parks and trails department with the City of Fredericton. He became involved with the local rugby scene, and for the past three years is back in his chosen field as a relief firefighter with the Fredericton Fire Department. "I've met so many great people since I've been in Fredericton, and this is a very special day for me and my family. I'm happy to be a Canadian, but I'm also glad that I still hold dual citizenship in Western Samoa as well." The citizenship ceremony was overseen by a number of dignitaries , including Lt.-Gov. Hermenegilde, Chiasson, MP Andy Scott, Mayor Brad Woodside and John Barrett, director of operations for Citizenship and Immigration Canada. Chiasson joked by welcoming the new Canadians "to the country that invented ice skates, maple syrup and the case of beer with the built-in handle." The day was also special for Jean-Jacques Tshimenga, his wife Sarah, and their three children, formerly of the Democratic Republic of Congo. "Canada Day is the day to celebrate the independence and freedom that we have in this country," he said.
