[Q]: Context: 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?
[A]: ineffective


[Q]: Context: Dabigatran is a direct thrombin inhibitor used to reduce the risk of stroke in patients with nonvalvular atrial fibrillation. For patients who present with an acute stroke despite dabigatran therapy, clinical data on the use of intravenous tissue plasminogen activator (IV-tPA) is limited. There is an anticipated increased risk of symptomatic intracranial hemorrhage (sICH) when using IV-tPA in patients on dabigatran therapy. In 2015, the humanized monoclonal antibody fragment idarucizumab was approved for rapid (minutes) reversal of anticoagulant effects of dabigatran. Dabigatran reversal with idarucizumab before administration of IV-tPA might reduce the risk of sICH. We report a case of a 69-year-old stroke patient on dabigatran for paroxysmal atrial fibrillation who presented with an initial National Institutes of Health Stroke Scale (NIHSS) of 12. There was no early evidence of ischemic stroke or hemorrhage on head computed tomography, and coagulation studies implied therapeutic dabigatran levels. After controlling blood pressure, dabigatran was reversed with idarucizumab, and IV-tPA was administrated beginning 197minutes after he was last seen at his baseline. Subsequent brain magnetic resonance imaging showed 2 punctate infarcts in the left temporal lobe and occipital lobe with no evidence of hemorrhage. The patient was discharged with an NIHSS of 1. Telephone follow-up 2 months later indicated that he was at his prestroke baseline, except for a complaint of worsened short-term memory. Idarucizumab reversal of dabigatran may reduce the risk of sICH and should be considered for acute stroke patients arriving in the IV-tPA time window. 
 Question: Which drug can be reversed with idarucizumab?
[A]: dabigatran


[Q]: Context: Former college classmates Martha Dobie (Shirley MacLaine) and Karen Wright (Audrey Hepburn) open a private school for girls. Martha's Aunt Lily (Miriam Hopkins), an aging actress, lives and teaches elocution at the school. After an engagement of two years to Joe Cardin (James Garner), a reputable obstetrician, Karen finally agrees to set a wedding date. Joe is related to the influential Amelia Tilford (Fay Bainter), whose granddaughter Mary (Karen Balkin) is a student at the school. Mary is a spoiled, conniving child who bullies her classmates, particularly Rosalie Wells (Veronica Cartwright), whom she blackmails when she discovers her in possession of a student's missing bracelet. When Mary is caught in a lie, Karen punishes her by refusing to let her attend the weekend's boat races. Mary goes home to her grandmother and twists a story so that she will not have to return to school that day. Karen learns what the story is from a father of a departing student and confronts Amelia about Mary accusing Martha and Karen of being lovers. Mary is foiled at convincing others that she personally saw the interactions between Martha and Karen. Mary coerces Rosalie to corroborate her story. Joe is frustrated by the situation, saying that he has finished cleaning up his grandmother's home, and maintains his engagement to Karen and his friendship with Martha. The two women intend to file a suit of libel and slander against Mrs. Tilford. Martha and Karen are isolated at the school. Aunt Lily returns after the suit has been lost because she would not return to testify on behalf of her niece and Karen. The incident had been circulated widely by the media. Joe wants to continue with his intention to marry Karen and wants Martha to restart life with them in a rural area where he has found a practice. Karen insists that Joe tell her whether he believes that there was a relationship between Martha and Karen. Joe tells Karen that he believes it's untrue. She then says that nothing ever happened and that she could not continue with the engagement. Rosalie's mother (Sally Brophy) discovers a cache of items among her daughter's belongings, including the bracelet inscribed to Evelyn. Mrs. Wells takes her daughter to Mrs. Tilford who, while walking over to meet her granddaughter, Mary, on the stairs collapses on the floor. Karen tells Martha that Joe will not come back. Martha is distraught at Karen's cryptic explanation and urges her to not let Joe go. Karen, however, wants to leave town with Martha the next day. She believes they can go where they will not be recognized and can start a new life, but Martha does not. As Martha tries to talk herself into believing she and Karen are just good friends, she realizes that she does truly love Karen. While Karen does not believe her, tries to dissuade her and maintains her own heterosexuality, Martha comes to believe she has loved Karen ever since they met and that she was simply unaware of the true nature of her feelings. Despite Karen's assurances to the contrary, Martha feels responsible for ruining both their lives and is appalled by her feelings towards Karen. Mrs. Tilford visits the two teachers. She has learned about the falsehood perpetrated by her; the court proceedings will be reversed and the award for damages settled. Karen refuses Mrs. Tilford's gesture. Martha no longer wants to continue with the conversation. Karen leaves her for a walk on the school grounds. Aunt Lily asks Karen about the whereabouts of Martha as her door is locked. Karen breaks loose the door's slide lock with a candleholder and discovers Martha has hanged herself in her room. After Martha's funeral, Karen walks away alone, while Joe watches her from the distance.
