Article: The only survivor of one of the two Sandy Hook Elementary School first-grade classrooms where Adam Lanza shot and killed 20 children tricked the gunman by playing dead,the girl's pastor said. "She ran out of the school building covered from head to toe with blood and the first thing she said to her mom was,"Mommy,I'm OK but all my friends are dead" Pastor Jim Solomon told ABC News' Lara Spencer this weekend "Somehow,at that moment, by God's grace,she was able to act as she was already dead."he said. The girl, a 6-year-old whose name is not being announced for privacy reasons,was the first student to appear from the lockdown at Sandy Hook,Solomon said.He said the young girl described the shooter to her mom in a way that only a young child can. "Well, she saw someone who she felt was angry and someone she felt was very mad,"Solomon said. "I think it's impossible without the help of God. She has wisdom beyond her years, for sure'' Of the 20 children killed on Friday in the Newtown,Conn., school, eight were boys and l2 were girls Six staff members,all female, were also killed. The gunman,whose mother was also killed by him before he went to the schoo1 classrooms, was found dead at the present spot. "The mom told me--and I thought this was very insightful --that she was suffering from what she felt was survivor's guilt because so many of her friends no longer have their children but she has hers," Solomon said how the girl's mother and father are handling the trauma ."I don't know whether l would have the type of faith that they have if the same thing happened to me." Question: What can we know from the text? Options: A: It is not difficult for the parents to handle the trauma. B: The girl's parents have asked for help from their pastor. C: The girl has helped the police in catching the gunman. D: The gunman has worked in the school.

A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode made of many carbon-based graphene sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available... Question: We can infer from the article that _ . Options: A: current rechargeable batteries usually last for 150 charges B: after one year's use, the newly developed batteries are less powerful C: batteries with more lithium ions are more powerful and charge faster D: further experiments may focus on improving the shape of graphene sheets
