Read the following article and select the best answer. Article: Every immigrant leads a double life. Every immigrant has a double identity and a double vision, being suspended between an old and a new home, an old and new self. The very notion of a new home, of course, is in a sense as impossible as the notion of new parents. Parents are who they are; home is what it is. Yet home, like parentage, must be legitimized through love; otherwise, it is only a fact of geography or biology. Most immigrants to America found their love of their old homes betrayed: they did not really abandon their countries; their countries abandoned them. In America, they found the possibility of a new love, the chance to nurture new selves. Not uniformly, not without exceptions. Every generation has its Know-Nothing movement. Its understandable fear and hatred of alien invasion is as true today as it always was, but in spite of all this, the American attitude remains unique. Throughout history, exile has been a disaster; America turned it into a triumph and placed its immigrants in the center of a national epic. The epic is possible because America is an idea as much as it is a country. America has nothing to do with loyalty to a dynasty and very little to do with loyalty to particular place, but everything to do with loyalty to a set of principles. To immigrants, those principles are especially real because so often they were absent or violated in their native lands. It was no accident in the '60 and '70s, when alienation was in flower, that it often seemed to be "native" Americans who felt alienated, while aliens or the children of aliens upheld the native values. The immigrant's double vision results in a special, somewhat skewed perspective on America that can mislead but that can also find revelation in the things that to native Americans are obvious. Psychiatrist Robert Coles speaks of those "who straddle worlds and make of that very experience a new world." "Home is where you are happy." Sentimental, perhaps, and certainly not conventionally patriotic, but is appropriate for a country... Question: What's the result of American's unique attitude toward immigrants? - Immigrants have played an important role in America's history. - Immigrants have endured more sufferings than those in other countries. - Immigrants have been a disaster to America's development. - Immigrants have posed fear and hatred on America.
Immigrants have played an important role in America's history.

Article: While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol related danger: drunken pedestrains. Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated more frequently and with higher blood alcohol levels than drunken drivers who are killed in accidents, various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood alcohol level of at least 0.10 which by law in most states signifies intoxication compared to only 25 percent of drivers in deadly accidents, according to recent federal data. Some types of pedestrain accidents have been declining nationally, especially those involving children, but the number of adult pedestrians who are drunk when killed in traffic has remained ly steady at 2500 a year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7000, or one of every seven highway accidents resulting in death. "We're dealing here, we think, with a very severe drinking problem that leads to a severe highway safety problem," said Richard Blomberg, president of Dunlap and Associates Inc, in Norwalk, Coon. w.w.^w.k.&s.5*u.c.#om.... Blomberg, whose consulting company found a very high rate of alcohol involvement in a controlled study of pedestrian accidents in New Orleans, was among several researchers who spoke on the topic at the annual meeting of the Research council's Transportation Research Board(TRB) in Washington in January. Pedestrian accidents have not received enough attention in the past, according to Kay Colpitts, who chairs the board's committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified about how to prevent disasters. Question: Among the causes of walkers' accidents, the most serious problem is . _ - long delays in traffic signals that may make people cross streets without paying attention to traffic rules - alcohol - a lack of adult keeping eyes on many children involved in accidents - former drunken drivers whose licenses are not allowed to use for a time
alcohol

*Question*
Read the following article and select the best answer. Article: 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. Question: What does Gallo think of the training programs involving role play with toy guns? - Searing - Violent - Ineffective - Helpful
**Answer**
Ineffective
