Example Input: Article: Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction.
Question: Which of the following describes a wearable computer?
Options: (A) It can be washed in a washing machine. (B) It is much heavier than a leather purse. (C) It can download songs from the Internet. (D) It is made of clothes conducting electricity.
Example Output: A

Example Input: Article: What do working mothers worry about the most? It's the kids of course. Whatever the setting, the question I get asked the most is "Will the kids be alright?" It has made me realize that we tend to look at the glass half-empty rather than half-filled when it comes to mixing work and family. We forget about all the benefits that we bring to our children when we work - and I'm not talking about the obvious financial benefits, although these of course shouldn't be taken for granted. About a year ago I remember getting a call from the school just as I was pulling up to the house after having driven 20 minutes to the school and 20 minutes back. "Mrs. Brown Quinn, your son asked us to call. He forgot his sports clothes. Can you come back to the school and drop them off?" I was exasperated ! I had already spent 40 minutes in aggressive weekday morning traffic. I replied, "Sorry, I'm working at the moment. I'm afraid my son needs to learn to be organized." Being a good parent requires delivering tough love sometimes. Kids need to learn to be independent. It can be a cruel and competitive world out there. Seeking interests, including business, outside of your kids, can give you that extra idea that you need not care for your kids with attention. This benefit of working isn't always immediately evident. It wasn't until our daughter went away to college that she realized why we had raised her in the way that we did. "Mom, I can't believe how so many of my friends struggle to manage things on their own. They are constantly calling their parents for help." You'll love that moment! After all those years of complaining about why you don't do this or why you don't give them that, your kids realize that tough love has made them better people.

Example Input: Article: When thinking about quitting... List all the reasons why you want to quit. Every night before going to bed, repeat one of the reasons 10 times. Decide surely that you want to quit. Try to avoid negative thoughts about how difficult it might be. Develop strong personal reasons in addition to your health and duties to others. For example, think all the time you waste taking cigarette breaks, rushing out to buy a pack, hunting a light, etc. Set a date for quitting--perhaps a special day like your birthday, or a holiday. If you smoke heavily at work, quit during your vacation. Make the date seriously, and don't let anything change it. Begin to prepare yourself physically: start a modest exercise, drink more water, get plenty of rest. Immediately after quitting... The first few days after you quit, spend as much free time as possible in places where smoking is forbidden, e.g. libraries, museums, theatres, department stores, etc. Drink large quantities of water and fruit juice. Try to avoid wine, coffee, and other drinks, which remind you of cigarette smoking. Start a conversation with someone instead of asking for a match for a cigarette. If you miss the sensation of having a cigarette in your hand, play with something else--a pencil, a pen, or a ruler. If you miss having something in your mouth, try toothpicks or a fake cigarette.
