You're in your office when you learn there's someone with a gun wandering outside. You can hear gunshots and screams. What do you do? That's the challenge for users of a new virtual reality program called SurviVR, designed to train employees how to deal with an active shooter situation in the workplace. The program works with HTC Vive, the virtual reality headset released earlier this year. An active shooter situation is when an armed person or people actively shoot in a small, populated area with the intention to kill. There were 20 such situations in the United States last year and 20 the year before, according to FBI statistics, resulting in a total of 231 deaths. This year saw the deadliest active shooter situation in US history , with 49 people killed in a nightclub in Orlando. In the training situation, users have four choices. They can lock themselves in the office. They can hide, perhaps in the office closet. They can run for an exit. Or they can use something in the office--a computer or a cup a pair of scissors-as a weapon to fight the shooter. This is an improvement on standard active shooter training. Gallo says, which typically teachers people to lock themselves in place and hide. The "lock down" method is often ineffective, he says, and has resulted in many deaths in recent years. In the training's basic level, no one gets killed. But as the trainings become more advanced, players who make a wrong choice be shot. There's no blood; the screen simply turns black slowly. If this sounds terrifying, that's the point, says Gallo. There are plenty of training programs to teach employees how to deal with workplace violence, sometimes involving role play with toy guns. But these trainings are basically games. Gallo says, with employees relaxed and even enjoying themselves. To teach people what they really need to know for an active shooter situation, they need to be scared. "SurviVR will take the fear and turn it into confidence." Gallo says. What would be the best title? A) A New Virtual Reality Program on Active Shooter Training B) What Should You Do When Meeting Gunshots in the Workplace? C) How to Deal with an Active Shooter Situation? D) Employees Need to Be Scared of the Workplace Violence.

Q: This is not a typical summer camp. Michelle Pawlaw and eight other teenage girls are participating in the three--day camp offered by the Arlington County Fire Department located just outside Washington. Firefighter Clare Burley is in charge of the program,who said the purpose is to try to get young women interested in considering the fire service as a career. The free-of-charge,overnight camp is designed to let the girls experience what firefighters do to protect the community. That includes some rigorous activities such as moving a fire victim. "I dindn't think I could pull that 170 pound body with a friend, but I was actually able to do it." she said. They take classes and learn how to climb the ladder on a fire truck, operate emergency tools and rescue an injured person. They also do their share of cleaning the firehouse and the equipment. "Every week without fail on a Saturday,the job is to wash all the equipment. And we wanted the girls to see this is what we do. This is a typical day in a firehouse,"she said. Firefighting is still a male-dominated service,but Burley says with 22 women on its force of 320 the Arlington County Fire Department is above the national average of 4.5 percent. She joined the department seven years ago. "We do everything that the guys do to the same standard. We are tested to the same standard. We are expected to operate at the same standard,"she said. Most of the girls say they had never thought about becoming a firefighter. but the camp was a great learning experience. "I think it is definitely not a job that only men can do. Women can do it just as well as men can,"said Michelle Pawlaw. What's the purpose of the summer camp? A) To tell the girls how to put firefighting knowledge into practice. B) To teach the girls what to do when caught in fire. C) To provide the girls with a typical summer camp. D) To attract more girls to take firefighting as a career.

Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with...
