[EX Q]: 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 _ .

[EX Q]: Article: Amanda Clement grew up in Hudson, South Dakota. Baseball was always her favorite sport. Once in a while her brother Hank and his friends would let her play first base in their games. More often, however, they asked her to umpire for them, because they knew her calls would be fair and there would be no arguing. One day in 1904, Amanda and her mother traveled to Hawarden, Iowa, to watch Hank play for the home team against Hawarden. When they arrived at the ball field, two local teams were waiting to play a preliminary game. The umpire hadn't arrived, so Hank argued that the teams should let his sister serve as umpire. The players finally agreed. Amanda, then sixteen and standing five feet, ten inches tall, made perfect calls. She was so good that players for the main game asked her to umpire for them and even offered to pay her. Thus, at sixteen, Amanda Clement became the first paid female baseball umpire of all time. She is honored in the Baseball Hall of Fame in Cooperstown, New York.
Question: Why did Hank and his friends often ask Amanda to umpire for them?
Options: (A) Because she called them brothers. (B) Because they wanted to make her happy. (C) Because no one else wanted to do it for them. (D) Because she knew the rules well and was fair.
