Article: As every computer owner knows, when their machines run a complex program they get pretty hot. In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that. Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere. A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy. Boaz Leupe, CEO of the start-up Nerdalize, says it's actually quite simple."We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe. The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center," says Leupe. One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server's processors so it cannot be used as the primary source. But he is ready to try it. "If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills." Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in... Question: Which of the following can be the best title for the passage ? Yes or no, is the answer "Data Servers Could Heat Private Homes"?
Yes

Article: One evening last summer, when I asked my 14-year-old son, Ray, for help with dinner, his response shocked me. "What's a colander ? " he asked. I could only blame myself. In the family, nobody else's hands went in the sauce except my own. But that night, as I explained with a touch of panic that a colander is the thing with holes in it, I wondered what else I hadn't prepared Ray for. As parents, while we focus on our sons' confidence and character, we perhaps don't always consider that we are also raising someone's future roommates, boyfriends, husbands, or fathers. I wanted to know that I'd raised a boy who would never ask the woman in his life, "What's for dinner?" So I came up with a plan: I would offer Ray a private home economics course. I was delighted to find that he didn't say no. For two hours, three days a week, Ray was all mine. One day, as his tomato sauce reduced on the stove, he washed and seasoned a chicken for roasting. Then he rolled out the piecrust and filled it with apples, all while listening to my explanation on the importance of preheating an oven. I knew that he would rather have been shooting hoops in the driveway than learning to mend socks with his mother--he tried to beg off sewing lessons, even though I insisted that one day, someone would find the sight of him fixing his own shirt very attractive-- but it couldn't be denied that he was learning, and more than just housekeeping. "I appreciate what you do as a mom," he told me one day. Ray now understands the finer points of cooking, and more importantly, he realizes there's nothing masculine about being helpless. Now, not only can he make his own dinner, but also he can make a big meal for his family. That's what I call a man. I'm glad that I prepared so great a present for my future daughter-in-law. Question: Why was the author shocked at her son's response? Yes or no, is the answer "Because he didn't know the common kitchen utensils ."?
No
