Which revision to the last sentence best concludes this story and reflects on the significance of the experience? As Abby ripped the wrapping paper off her birthday present, I remembered all the hard work that had gone into making it. For a week, I had written, edited, and rewritten a story about Amazing Abby and her big sister Super Sophia. Then I spent days drawing and coloring illustrations to match the story. Once it was finished, I designed a cover and hand-stitched the pages together. It was a lot of work, but the look on Abby's face when she opened her gift made it all worth it. Abby might one day forget about that handmade book, but I will never forget how I felt when I saw the joy my gift brought to her. All in all, it was a memorable birthday. A. People should learn not only to receive gifts happily but also to give gifts unselfishly, just like I did with Abby. B. It made me realize that giving a thoughtful gift can be one of the most satisfying things in the world. C. Abby read that book over a hundred times in the next few months, and that always put a smile on my face. D. Now that I know how much fun it can be to write books, I might try writing another one someday on a more grown-up subject.
