Just two years ago,the condition left Laresce in so much pain that she couldn't even take part in sports.But now she has six British and World Champion power lifting records.It's an incredible achievement. Laresce's trainer Tania George said her condition is the secret to her success."She has more flexibility in her back than most people,which gives her the technique of bending her back strongly and safely.Most power lifters would kill to try to bend their backs like Laresce.She has perfected the technique to lift incredibly heavy weights,"Tania said. "I used to suffer a lot of pain from my hypermobility.I remember coming home from school with pains in my knees,joints and hips.It would stop me doing normal things at schoo1.The pain would be so much that some nights I couldn't sleep at all and I just couldn't face going to school like that.And after each dislocation,I had to do six months of physiotherapy to recover,"said Laresce. However, since taking up the sport of power lifting 18 months ago she is now effectively cured."really enjoyed the feeling of power I got and the excitement of people encouraging me to do my very best,"she said. "I've made lots of friends a It's an incredible feeling when everyone's cheering me on.It's the support of other people that makes the difference to winning.Becoming a champion was a big surprise--I just started off for fun and wasn't expecting anything.So to win six titles over just a few months was amazing."

Article: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner.
Question: How did the scientists conduct the experiment?
Options: (A) By leaving dogs to women who are either happy or angry. (B) By mixing the selected dogs together. (C) By rewarding only half of the dogs touching the screen. (D) By showing digital pictures of women's happy or angry faces.
