Article: A sobbing little girl stood near a small church from which she had been turned away because it "was too crowded." "I can't go to Sunday School," she sobbed to the pastor as he walked by. Seeing her shabby appearance, the pastor guessed the reason, and, taking her by the hand, took her inside and found a place for her in the Sunday School class. The child was so touched that she went to bed that night thinking of the children who have no place to worship Jesus. Some years later, this child lay dead in one of the poor buildings and the parents called for the kindhearted pastor, who had befriended their daughter, to handle the final arrangements. As her poor little body was being moved, a worn purse was found which seemed to have been picked up from some trash dump. Inside was found 57 cents and a note scribbled in childish handwriting which read, "This is to help build the little church bigger so more children can go to Sunday School." For two years she had saved for this offering of love. When the pastor tearfully read that note, he knew instantly what he would do. Carrying this note, he told people the story of her unselfish love and devotion. A newspaper learned of the story and published it. It was read by a Realtor who offered them a parcel of land worth many thousands. When told that the church could not pay so much, he offered it for 57 cents. Church members made large donations. Checks came from far and wide. Within five years the little girl's gift had increased to $250,000, a huge sum for that time. When you are in the city of Philadelphia, look up Temple Baptist Church, with a seating capacity of 3,300 and Temple University, where hundreds of students are trained. Have a look, too, at the Good Samaritan Hospital and at a Sunday School building which houses hundreds of Sunday scholars, so that no child in the area will ever need to be left outside during Sunday school time. Question: How did a Realtor help the church? Yes or no, is the answer "He offered the church a piece of land for 57 cents."?
No

Article: DNA is a substance that makes up genes. Everything alive has genes. Plants have genes. Animals have genes. You have genes. Genes are the basic units of heredity . Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree's genes tell what shape its leaves will be. A cat's genes tell what color1 its fur will be. Your genes tell what color1 your eyes will be. Your genes tell what color1 your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells. An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits , Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were called genes. In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases--diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by _ genes through a process called gene therapy. Question: In the last sentence, the word "altering" can best be replaced by _ . Yes or no, is the answer "changing"?
