Article: Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iphone application Mealsnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately. Mealsnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iphone applications. The applications gives users a quick reply. To do that, it matches the taken picture to a databank containing the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed. We started with something simple -- an apple. A couple of minutes later the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of mixed salad bowl. Mealsnap replied that the bowl contained "yellow rice with corn, boiled eggs and beans" and that the food was between 532 and 798 calories. Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That's why it is so popular among those who are trying hard to lose weight. In addition, Mealsnap can serve as a food diary. No need to write down what they've eaten, the photos will be stored. Then users can keep a visual log . Mr. Smith said: "It's like a food journal, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological change that can help people on their health journey. Knowing the calorie range makes me think more about what I'm eating. Question: 63. Which would be the best title for the passage? Yes or no, is the answer "Mealsnap iphones count your calories"?
No

Article: One of the most recent social changes taking place in the world is social networking. Social networking has been in existence for at least 150 years, and probably longer than that. In the times before the invention of the computer and the World Wide Web (WWW), social networking was done in person. People who had similar likes and interests would gather together to share experiences, make new friends, and improve their businesses. On the Internet, social networking websites made their first appearances during the late 1990s. The first major social networking website in the United States was MySpace. MySpace allowed its users to exchange messages, share pictures, and make new friends in a way that was never thought of in the past. With MySpace, people who did not go out much could reach out to others from their own homes. In 2004, Facebook was created. It was first a website created for use by Harvard University's students and teachers, but it soon expanded to include just about everyone. It is now larger than some of the largest companies in the world. It is a website that is changing all the time. Facebook has completely changed the way people stay connected with each other and the rest of the world. The way it works is simple. Users can set up a new account easily. All a new user needs is an email address to start. Once a person has created an account and his friend also has his own Facebook page, he can invite his friend by sending a request out to him. Once you get started, making new friends will come easily. Question: What do new users of Facebook need to create an account? Yes or no, is the answer "An email address."?
Yes

Article: When doctors urge overweight kids to pick up more activities,reading probably isn't what they have in mind. Yet a new study by fatness researchers at Duke University finds that the simple act of reading--depending on the choice of material--can cause weight loss in teenage girls. The study's experimental group included 31 fat girls aged 9 to 13,who took part in the Healthy Lifestyles Program at Duke Children's Hospital. The girls read a novel called Lake Rescue,whose protagonist is an overweight teenager who struggles with low selfesteem,feelings of loneliness and teasing because of her size. A group of 33 girls read a different book called Charlotte in Paris,which did not have an overweight character,and another group of 17 girls read neither book. At the end of the sixmonth experiment,all the girls who read books had lost weight,but the girls who read Lake Rescue lost more. They lowered their body mass index (BMI) by 0.71,compared with 0.33 in the Charlotte group,an average 0.05 increase among the nonreaders. The idea behind the study,says Dr Sarah Armstrong,director of Healthy Lifestyles,was to find a way to encourage the girls without adopting the restrictive and often authoritative voice of so many other nutrition and diet programs. Lake Rescue was the perfect instrument,says Armstrong;it presents a likable character to whom the girls could relate and whom they could learn from. As the book progresses,its protagonist learns to make healthier lifestyle choices and finds an adviser to help keep her on track. Armstrong says," _ learns that she can become healthier,and the 'I can do it' feeling resonates with the teenage girls." Question: How many girls took part in the experiment? Yes or no, is the answer "81."?
No
