High in the sky, a group of birds fly past. The 5-foot-tall creatures are whooping cranes, the tallest birds in North America noted for its loud call. The wild animals appear to be following much larger birds. But those aren't birds at all. They are three-wheeled aircraft called trikes , and the pilots flying them are wearing white helmets and white gowns. That plan might sound like a stupid idea, but it's not. The pilots are from an organization called Operation Migration. They are helping the whooping cranes learn to migrate, or move from one area to another when the seasons change. The cranes are endangered. In 1941,the species had dwindled to roughly 20 birds because of hunting and habitat loss. US wildlife officials counted 149 whooping cranes in November 1995,the most since the American government began taking censuses in the 1930s.Today,about 380 remain. In the fall, whooping cranes are supposed to migrate south. However, many of them don't know how. "With so few birds left, young whooping cranes typically don't have parents around to teach them," explains pilot Joe Duff. That's where the trikes come in. Each October, pilots dress up as whooping cranes and take to the skies in Wisconsin. The young birds follow them because they think the trikes are big whooping cranes. It takes about three months to reach south--with plenty of rest stops on the way. The pilots lead the cranes to refuges, or protected areas, in Florida. This spring, the birds will migrate north by themselves--no trikes needed! "It's nice because you know the birds are going to make it," Duff told WR News. What's the main idea of the passage? A) Baby whooping cranes don't have parents around. B) Pilots show baby whooping cranes how to migrate. C) Whooping cranes are becoming endangered. D) Whooping cranes are a clever species.

Ques: 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 does Gallo think of the training programs involving role play with toy guns? A) Searing B) Violent C) Ineffective D) Helpful

Question: Do you suffer from cybersickness? The rise of mobile phones has been blamed for a number of social ills, but your smart phone may also be making you physically sick as well. Scientists have identified a condition called "cybersickness", which they say is the digital version of motion sickness. The phenomenon, which affects up to 80 percent of the population who own smart phones or tablets, leads to feelings of sickness and unsteadiness. It is caused by seeing fast motion on a screen, which covers anything from a car chase in a film to scrolling through web pages on your phone. The more realistic the visual content appears to you, the higher your chances of getting cybersickness are . The condition was identified in a piece in the New York Times in which British and US experts said that it needed solving. Motion sickness leaves sufferers feeling ill because they feel movement in your muscles and your inner ear but do not see it. The mismatch in digital sickness is the opposite--you see movement on the screen but do not feel it. The effect is the same and the symptoms include a headache, wanting to throw up, confusion and the need to sit down. Often cybersickness shows itself in a subtle way and sufferers put it down to stress or eyestrain. Steven Rauch, a professor of otolaryngology at Harvard Medical School, said: "Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don't agree, that's when you feel dizziness and sickness. " Some studies that have been carried out into cybersickness found that women are more _ than men, the New York Times reported. Those who have Type A' personalities--meaning they are confident and determined--are more likely to suffer from cybersickness as well. Among those who have reported experiencing the condition have been video gamers who spend hours playing fast paced games. Engineers at Oculus VR, the virtual headset manufacturer, have admitted that digital motion sickness is one of their biggest problems. What's the difference between motion sickness and digital sickness? A) Digital sickness means sufferers see movement but do not feel it. B) Digital sickness means sufferers feel movement but do not see it. C) Motion sickness means sufferers see movement but do not feel it. D) Motion sickness means sufferers don't see or feel movement
