Question: Article: Heather Jack and her family, including her two children, usually spend the Christmas holidays preparing a feast--for others to eat. Last Christmas Eve, they went to a house in the neighborhood and prepared a dinner for an elderly woman and her son, who has muscular dystrophy . They stayed for an hour and chatted before heading home to prepare for a visit from Santa  .  "I think it is that kind of direct experience that many find so meaningful," says Heather, president and founder of The Volunteer Family, a Boston-based organization dedicated to matching families with volunteer opportunities, both during the holidays and year-round. "It's a great way for parents to involve the kids." In a holiday season that stretches from before Thanksgiving to just after the New Year, it's nice to hear stories about people with their children giving instead of receiving. Last December Gary and Debra Danoff and their two teenage sons drove to the Washington, D. C. Jewish Community Center(JCC) and spent Christmas morning in the Center's kitchen preparing a feast for homeless shelters.  By choosing to prepare meals for the homeless, the Danoffs bring together a belief in community service with their love of cooking, "It feels good to prepare food with our kids for other people at Christmas," says Gary. "We want them to know that many people don't have the ability to go to the supermarket and pick the foods they want to eat and pay for them." The Danoffs were in good company. Across the city, at least 1000 volunteers with their children went across the region to provide food to the poor people as part of the D. C. JCC's annual "December 25th Day of Service", now in its 22nd year.

Question: Article: What a great project this is, building your own greenhouse! If you're a gardener, then a greenhouse is necessary no matter where you live. As long as you've got some good plans, it's possible to build a backyard greenhouse within just a few days. It's a great way to impress the neighbors! Metal greenhouses are practical, I agree, but they look ugly. If you build your own backyard greenhouse from wood, you'll end up with a lovely looking Victorian-style greenhouse, which will last very long if you treat it with the correct wood protection. Of course you'll save a lot of money in the process too. How much exactly? It's difficult to say as it depends on how much glass costs where you live. After all, there isn't much wood required, as it's only the actual frame  that is wooden. To make sure you save the most money, it's best to take your plans to wherever you plan to buy your materials. That way you won't end up wasting any money on unnecessary materials. To be honest, saving money is not the main reason for building your own greenhouse. It's the fun you'll get from building it and the pleasure you'll get from showing it off to your friends and family that makes the project worth doing. Nothing beats the feeling when someone asks you where you bought something and you turn around and say "Oh, actually, I built it myself!" That feeling is priceless! You'll never feel like that over something you've bought! 
 Question: According to the author, it is better to build   _  . 
 Options: (A) a metal greenhouse (B) a grass greenhouse (C) a wooden greenhouse (D) a brick greenhouse

Answer: C


Question: Article: My dad loved pennies, especially those with the elegant stalk of wheat curving around each side of the ONE CENT on the back. Those were the pennies he grew up with during the Depression  . As a kid, I would go for walks with Dad, spying coins along the way--a penny here, a dime   there. Whenever I picked up a penny, he'd ask, "Is it a wheat?" It always thrilled him when we found one of those special coins produced between 1909 and 1958, the year of my birth. One gray Sunday morning in winter, not long after my father's death in 2002, I was walking down Fifth Avenue, feeling  _ . I found myself in front of the church where Dad once worked. I was warmly shown in and led to a seat. Hearing Dad's favorite "A Mighty Fortress Is Our God", I burst into tears. We'd sung that at his funeral. After the service, I shook the pastor's hand and stepped onto the sidewalk--and there was a penny. I bent to pick it up, turned it over, and sure enough, it was a wheat. A 1944, a year my father was serving on a ship in the South Pacific. That started it. Suddenly wheat pennies began turning up on the sidewalks of New York everywhere. I got most of the important years: his birth year, my mom's birth year, the year he graduated from college, the year he met my mom, the year they got married, the year my sister was born. But alas, no 1958 wheat penny--my year, the last year they were made.     The next Sunday, after the service, I was walking up Fifth Avenue and spotted a penny in the middle of a crossing. Oh, no, it was a busy street;cabs were speeding by--should I risk it? I just had to get it. A wheat! But the penny was worn, and I couldn't read the date. On arriving home, I took out my glasses and took it to the light. There was my birthday! I found 21 wheat pennies on the streets of Manhattan in the year after my father died, and I don't think that's a coincidence.
