Why You Should Start Work at 10AM | This might be why, he adds, the traditional nine to five is so ingrained; bosses control working hours and many of them are in their mid-50s and older so “it is best for them”. So, should workplaces have staggered starting times, too? Should those in their 50s and above come in at 8am, while those in their 30s start at 10am and the teenage apprentice be encouraged to start at 11am? Kelley says that synchronized hours could have “many positive consequences. The positive side of this is people’s performance, mood and health will improve. It’s very uplifting because it’s a solution that will make people less ill, and happier and better at what they do.” | 1Int
| According to Kelley, how would staggered starting times benefit workplaces? | 4 | [
"Work would be done more effectively",
"Workspaces could stay open longer",
"More 50-year-olds would be employed",
"Lunch breaks would become shorter"

Why You Should Start Work at 10AM | There would probably be fewer accidents as drivers would be more alert, he says. It could spell the end of rush hour as people stagger their work and school-run times. A later start to the day for many, says Kelley, “is something that would benefit everyone, particularly families. Parents go and try to wake up teenagers who are waking up three hours too early. It creates tensions for everybody.” So, what time does Kelley start work? “I am 67 so that means I’m back to being ten years old and I get up just after six. I wake naturally.” And, yes, he says he finds the start of his working day much easier now than he did when he was younger. | 0Adv
| How might staggered starting times for work affect traffic, according to Kelley? | 5 | [
"There would be no more rush hour",
"Rush hour would end earlier",
"Most traffic would occur later in the day",
"More people would be able to bike or walk"

Will Drones Soon Be Delivering Packages to Your Doorstep | How far away are we from a world where drones deliver packages? If Amazon is to be believed, not far at all. Others are not so sure: technical progress past this point isn’t merely a matter of invention; it’s a matter of public safety. Paul Misener, Amazon’s vice-president of global public policy, told a congressional hearing recently that his company would be ready as soon as all the rules were in place. The Federal Aviation Authority (FAA) will finally have regulations governing the commercial use of unmanned aircraft by June 2016. But the technology has a long way to go before then and larger machines aren’t airway-legal at all yet – only drones up to 25kg will be covered and the FAA points out in the proposed rules that, if you’re going to crowd the skies with radio-controlled flying robots, they had better all be using different radio frequencies that nobody can jam or hijack. | 0Adv
| When does Amazon claim it will be ready to deliver packages using drones? | 0 | [
"Once the FFA releases their rules",
"Once the FFA approves Amazon’s existing drones",
"Amazon says it is not sure when this will happen",
"Once the FFA regulations are approved by Congress in 2017"

Will Drones Soon Be Delivering Packages to Your Doorstep | Professor Sanjiv Singh, who runs a cargo delivery company called NearEarth, said that piloting a state-of-the-art drone was a little more like leaving it a trail of breadcrumbs: go to this altitude, perform this short task, go back home. But even short flights from a mobile landing pad pose serious logistical problems, he said. “They’re not proposing to deliver from one uninhabited place to another uninhabited place; they’re proposing to deliver from a warehouse to where the consumer is, which is likely an urban area,” he said. “There are going to be hazards along the way that the vehicle is going to have to detect. Maybe there will be terrain that the map doesn’t know about. Even then, maybe there’s construction equipment that wasn’t there but is there now. Maybe GPS signals are blocked, in which case it’s going to have an incorrect idea about where it is.” All this is surmountable, he said – but it’s difficult. | 0Adv
| Why does Sanjiv mention GPS systems? | 1 | [
"To provide an example of a critical problem that may arise during drone flight",
"To argue that people have incorrect ideas about how they work in drones",
"To illustrate how easy it is to fly drones",

Will Drones Soon Be Delivering Packages to Your Doorstep | Professor Sanjiv Singh, who runs a cargo delivery company called NearEarth, said that, to pilot a state-of-the-art drone, you simply give it some basic instructions: go to this altitude, perform this short task, go back home. But even short flights from a mobile landing pad could cause serious logistical problems, he said. “They’re not going to deliver from one uninhabited place to another uninhabited place; they’re going to deliver from a warehouse to the consumer, which will probably be an urban area,” he said. “There are going to be hazards that the vehicle is going to have to see. Maybe there will be terrain that the map doesn’t know about. Then, maybe there’s construction equipment that wasn’t there before but is there now. Maybe GPS signals are blocked, in which case it’s going to have an incorrect idea about where it is.” All these problems can be solved, he said – but it’s difficult. | 1Int
| What is Professor Singh worried will happen when the drone is unable to access GPS signals? | 1 | [
"It will have unreliable knowledge of its current location",
"It will deliver to an incorrect location",
"It will be unable to follow simple instructions like “go to this height”",
"It will stop responding to control commands from the operator"

Will Drones Soon Be Delivering Packages to Your Doorstep | Professor Sanjiv Singh, who works for delivery company NearEarth, said that flying drones is quite simple – you just give it some basic instructions: go to this height, do this short task, go back home. But even short flights from a mobile landing place could cause serious problems, he said. “They’re not planning to deliver in areas where nobody lives; they’re planning to deliver from a warehouse to the consumer, which will probably be in a town or city,” he said. “The drone will have to see hazards. Maybe there will be things that the map doesn’t know about. Maybe there will be construction equipment that wasn’t there but is there now. Maybe GPS signals will be blocked so it’s going to have an incorrect idea about where it is.” All this can be solved, he said – but it’s difficult. | 2Ele
| Why does Sanjiv mention GPS systems? | 1 | [
"To provide an example of a critical problem that may arise during drone flight",
"To argue that people have incorrect ideas about how they work in drones",
"To illustrate how easy it is to fly drones",
"To discuss how common they are"

Will Drones Soon Be Delivering Packages to Your Doorstep | One major problem is maintaining radio contact with a drone and planning for what happens if that contact breaks. “If you have an off-the-shelf UAV (unmanned aerial vehicle), it’ll just keep going and crash into the ground,” said roboticist Daniel Huber. “Technologically, most of the things that are needed for this are in place,” said Huber. He is working on a program that proposes using drones to inspect infrastructure – pipelines, telephone lines, bridges and so on. “We’ve developed an exploration algorithm where you draw a box around an area and it’ll autonomously fly around that area and look at every surface and then report back.” | 0Adv

"It will collide with the ground",
"It will crash into an obstacle",
"It will fly around a certain area and look at every surface for a proper landing site",

Will Drones Soon Be Delivering Packages to Your Doorstep | Huber said about Amazon: “I have heard them say that many packages are lightweight – a drone can carry a kilogram for 15 minutes. If you have a vehicle that can go into a neighborhood, it can deliver from that base. You need a 15-minute distance and typical off-the-shelf drones have about that distance.” It’s one way, he said, of making sure the surrounding population is relatively safe. “The larger the distance the drone travels, the more dangerous it becomes.” Of course, safety remains a major concern – Singh points out that, for a commercial aircraft to be considered skyworthy, it has to prove a rate of one serious failure every one million hours. Drones, he said, are “one or two orders of magnitude away” from that benchmark. “The Reaper drone has one failure in 10,000 hours,” Singh said. An oil leak, by the way, doesn’t count as catastrophic failure – something has to fall out of the sky. | 0Adv
| What happens as you increase the distance a drone travels to deliver a package? | 3 | [
"The drone becomes more dangerous to people",
"It’s harder for the drone to spot dangers",
