Article: People should be warned against using mobile phones outdoors in stormy weather because they may"be struck by lightning",according to doctors. Three experts have described how a teenage girl was struck by lightning while using her phone in a large London park.The girl,aged 15,recovered,but a year later was still wheelchair-bound and found to be suffering complex physical and emotional problems. The girl also had a perforate eardrum on the side where she had been holding the mobile phone.She was having general recovery in Northwick Park Hospital,Middlesex. Swinda Esprit,a senior house officer, said that while the brain and muscle damage was similar to that of many lightning victims--who can experience heart attacks on being struck--the ear problems were not. She said that the damages were particularly relevant for people who might be involved in less serious lightning incidents,who might otherwise recover, but would never get their full hearing back if struck while on the phone. "We were shocked by the damage,which is why we wanted to draw attention to it,"Dr Esprit said."A year on and she still was suffering these difficult hearing." They added that three other cases had been reported in newspapers in China,South Korea,and Malaysia.In the Malaysian case,a sales executive was killed by lightning while talking on his phone during a thunderstorm near Kuala Lumpur. "All these events resulted in death,"the doctors wrote."This rare phenomenon is a public health issue,and education is necessary to stress the risk." The Australian Lightning Protection Standard recommends that metallic objects,including cordless or mobile phones,should not be carried outdoors during thunderstorms.However, "the United States National Weather Service says on its website that both are safe to use "because there is no direct path between you and the lightening". Paul Taylor, of "the Met Office'',said the ear injuries were a consequence of mobile phones being metal,and not related to radio waves. Mr. Taylor said that mobile phones should be...

Q: Read the following article and select the best answer. Article: Liah Kaminer remembers hearing the shock from the audience when two seniors rapped the words "raise your hand like a Nazi" at a school assembly during her sophomore year. It wasn't the only instance of anti-Semitism that Kaminer, 17, of Hall High School in Connecticut, says she witnessed at her school. There were other comments, like a boy asking two other students in her class if they were Jewish. When they replied that they weren't, he said, "Oh, good." Kaminer recalled. He patted them on their backs and said, "You're one of us." Kaminer, who is Jewish, said she was hurt by the remark, and after a while she got tired of seeing such comments swept under the rug . So she decided to take action. After reaching out to the administration and connecting with social studies department supervisor Stephen Armstrong, Kaminer and Armstrong put together a class on anti-Semitism. They presented it to every ninth-grade social studies class during the last week of school this year. In the class, Kaminer and Armstrong showed a clip from the ABC show, What Would You Do? where actors portrayed a Jewish couple and a bakery employee who yelled at them with anti-Semitic comments. They had class discussions about what stereotypes students had heard. "I was a little surprised and confused by how much of this still goes on at Hall." Armstrong said. "That's why we're doing this. Although students are taught about the Holocaust in history classes, it's a pity that kids are seldom asked to think about this topic in a present-day situation." "The fact that a teenager was teaching her fellow students made the class more effective." Armstrong said. "I could have done it - a couple of classes I did it myself - but it was a lot more effective when a kid was with me. It wasn't just some teacher talking. It was a kid who had experienced some of the stuff very personally." Question: We can infer from the article that _ . - today's American kids know little about the history of the Nazis and the Jewish people - Armstrong believed the special class made the students have a better understanding of anti-Semitism at the school - teenager-teaching methods will become popular at the school because of the success of the special class - Armstrong had already noticed the problem of anti-Semitism before Kaminer turned to him
A: Armstrong believed the special class made the students have a better understanding of anti-Semitism at the school
