Problem: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

Problem: Article: Roll over, sit and fetch aren't commands normally given to a robot, but the smart toy company WowWee has developed a new way of owning a puppy. CHIP (Canine Home Intelligent Pet) is a robotic dog with blue LED eyes and pointy ears and can sit, shake, dance and make all types of dog noises. It also has tracking capabilities to help locate its owner. "The beauty about CHIP is that it has its own thing going on," said Sufer, CTO at WowWee. "It has its own life and own kind of intelligence. Even if you're not around, it's always doing something." CHIP uses wheels to get around and is loaded with sensors that give it a 360-degree view to find its ball. The pup is Bluetooth enabled, which connects to a wristband worn by its owner. The wristband, similar to a watch, displays icons for different commands such as a thumb-up, which allows you to give your pup a digital belly rub. With its owner wearing a smart wristband, it can even follow him around the room. "We worked on CHIP for about five to six months," Davin Sufer, told dailymail.com, "We typically come up with a concept, model and product and get it on shelves within a year." The company plans to start shipping units by next fall, which will allow them to load up the robotic dog with sensors and add many more animated responses per-owner interactivity. The high-tech toy company made its debut in 2004 by releasing the 1.5 foot RoboSapien, which sold millions of units. MiP, which hit shelves last year, is a seven inch tall robot covered in white with black accents. Users can direct it, change its emotions and make it dance to any song on your iPad. It's loud, fast and active. About 15 years ago, a company called ToyQuest developed the first ever electronic robotic dog---Tekno, the Robotic Puppy. The company sold over seven million units in the first season and 40 million more during its original four years of production. Tekno was built with over 160 emotions and instructions, but most importantly offered consumers a quick look into the future.
Answer: it can do something without instructions
Solution:
According to Sufer, the amazing characteristic of CHIP is that _ .
