[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: Week 10 featured the top-ranked defenses (by yardage against) in each conference, as the Lions hosted the Dolphins. Detroit got off to a quick start. Matt Prater kicked a 26-yard field goal on the opening drive of the game. Later in the first quarter, Calvin Johnson, playing in his first game since Week 5, caught a 49-yard TD pass from Matthew Stafford for a 10-0 lead. Miami managed a 23-yard Caleb Sturgis field goal before halftime, making the score 10-3. The Dolphins took the lead in the third, starting with a 50-yard Stugis field goal. Next, Earl Mitchell blocked Prater's 42-yard field goal attempt, and Dion Jordan returned the ball to the Lions 3-yard line. On the next play, Ryan Tannehill connected with Mike Wallace for the touchdown, putting Miami ahead, 13-10. Prater made good on a 50-yard field goal early in the fourth quarter to knot the score at 13-13, but Sturgis' 20-yarder put Miami back on top by 3. As in the previous two games, the Lions had to rally on their final drive to win the game. Starting at their own 26 with 3:13 left in the game, the drive culminated with Stafford's 11-yard touchdown pass to Theo Riddick, putting the Lions ahead for good, 20-16. This was the third straight game in which the Lions trailed at the two-minute warning, then went ahead on their final drive. It was the second time in a month that Miami had lost a game in the final seconds, following a Week 7 loss to Green Bay in which the final touchdown was scored with 3 seconds remaining. According to STATS Inc., this is the first time Detroit has started a season 7-2 since 1993.
Question: Which player threw the last touchdown pass of the game?
[A]: matthew stafford

[Q]: Context: Most sedimentary rocks form from sediments. Sediments are small pieces of other rocks, like pebbles, sand, silt, and clay. Sedimentary rocks may include fossils. Fossils are materials left behind by once-living organisms. Fossils can be pieces of the organism, like bones. They can also be traces of the organism, like footprints. Most often, sediments settle out of water (Figure 4.13). For example, rivers carry lots of sediment. Where the water slows, it dumps these sediments along its banks, into lakes and the ocean. When sediments settle out of water, they form horizontal layers. A layer of sediment is deposited. Then the next layer is deposited on top of that layer. So each layer in a sedimentary rock is younger than the layer under it. It is older than the layer over it. Sediments are deposited in many different types of environments. Beaches and deserts collect large deposits of sand. Sediments also continuously wind up at the bottom of the ocean and in lakes, ponds, rivers, marshes, and swamps. Avalanches produce large piles of sediment. The environment where the sediments are deposited determines the type of sedimentary rock that can form. Sedimentary rocks form in two ways. Particles may be cemented together. Chemicals may precipitate. Over time, deposited sediments may harden into rock. First, the sediments are compacted. That is, they are squeezed together by the weight of sediments on top of them. Next, the sediments are cemented together. Minerals fill in the spaces between the loose sediment particles. These cementing minerals come from the water that moves through the sediments. These types of sedimentary rocks are called clastic rocks. Clastic rocks are rock fragments that are compacted and cemented together. Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded. In breccia, the stones are angular. Sandstone is made of sand-sized particles. Siltstone is made of smaller particles. Silt is smaller than sand but larger than clay. Shale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. Chemical sedimentary rocks form when crystals precipitate out from a liquid. The mineral halite, also called rock salt, forms this way. You can make halite! Leave a shallow dish of salt water out in the Sun. As the water evaporates, salt crystals form in the dish. There are other chemical sedimentary rocks, like gypsum. Table 4.1 shows some common types of sedimentary rocks and the types of sediments that make them up.
