For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank. A Live Map of Everywhere on Earth: Frightening or Cool? Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, (21)______ (alert) you to any traffic, pedestrians, animals, or other things nearby. Routes and names of roads appear over the livestream. It’s like the map has come to life. This type of map isn’t available yet. But it could be soon. In 2014, the Worldview-3 satellite (22)______(launch) into space. Even though it circles round Earth at more than 370 miles (600 km) away, it can capture images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smartphone (23)______ (hold) in your hand. It can tell what types of cars are traveling down a road. But it can’t identify your face or read the cars’ license plate numbers . . . at least not openly. According to some reports, this satellite and other US spy satellites have the technology to take even (24)______ (sharp) images, with a resolution of up to around 4 inches (10cm).

At the same time, live, detailed maps of Earth’s surface (29)______ aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly and accurately reveal people in danger (30)______ ______ they could help rescuers determine the safest routes in or out in time. Higher detail may make it possible for farmers to watch over their crops or for prospectors to find minerals. What do you think? Do you wish everyone could access high-detail live maps of Earth’s surface?
