[Q]: Article: You're on the third lap around the car park, there are no open spaces, and you're already 15 minutes late for your appointment. Right now you're wishing you could jump out of the car and let it go to find its own spot.     Now there's an app for that. Virtual Valet lets your smartphone tell your car to park without you in it. "You pull up to the roadside, push a button on your smartphone and the car takes care of everything else," says Aeron Steinfeld, the lead researcher for the project at Carnegie Mellon University in Pittsburgh, Pennsylvania.     To find its own spot, the system uses a sensor suite similar to ones found in many luxury cars. This includes a motion sensor that scans for moving cars and pedestrians, and a forward-facing laser rangefinder normally found in adaptive cruise control to determine the distance of objects in front of the car. Information from these sensors is then fed to an onboard computer to plot the vehicle's course. The users can watch the whole process from their phone.     Better still, it will be affordable. The team has spent the last year moving from high-end imaging and processing equipment to less expensive components. In experiments, the vehicle was able to navigate through a crowded parking structure, find an empty spot, and park all on its own. And the greatest appeal of the Virtual Valet Parking App is that it requires no change to existing parking facilities or infrastructure.     For the moment, the only car equipped for control by Virtual Valet is Carnegie Mellon' modified   Jeep Wrangler, which the researchers have named NavLab11. But Steinfeld hopes that major car manufacturers will adopt the technology.     It might be more than technology that holds up the show, however. Self-driving cars have been licensed in only three US states -- California, Nevada and Florida -- and it's unclear how this app would agree with self-driving laws. Until these questions are settled, your insurance provider might be unwilling to cover a ding   from a parking incident. 
 Question: We can infer from the text that   _  . 
 Options: (A) no car manufacturers show interest in the technology (B) the technology is now widely used in the US (C) there will be some difficulty in promoting the technology (D) the technology conflicts with self-driving laws in the US
[A]: C


[Q]: Article: We live in central Phoenix, near the canal . Every day I used to see a homeless old man and his scruffy little dog hanging out down there. I would tell my husband we should give him food for the little dog. It wouldn't have been a problem; we have our own "mini farm" of animals! But he would say "OK!" and then blow the idea off because of our business. Being in Phoenix, Arizona, you can just imagine how hot it gets here, but his winter was really chilly! I had just come from KFC with take-out food for dinner. As I was turning by the canal, the man and his dog were sitting right there all bundled up. Even the doggy had a coat on! Not even thinking about it, I pulled into the parking lot along the canal and piled up a plate of chicken with all the fixings for the man and his little buddy . I gave it to him with a soda and a bottle of water for the little dog. He said, "Thank you, sweetie. You are an angel." And there were tears welling up in his eyes! I told him he was so welcome, and then went home. When my husband dug into the KFC bag he asked, "Were you hungry, or what?" I told him what I did and he said, "Only you!" Then he told me I had done a good thing. A few weeks later, we were walking along the canal and found the man walking to me, with his little dog. He asked whether I would mind adopting the dog. With tears in eyes, he said it had gotten too hard for him to care for the dog. He added that he was planning on heading to Washington State but his dog wouldn't have been up to it, so he hoped to give it to me. "Only you! In this city, you are the only person I can believe in!" Now, every time I watch and pat the dog lying near the fireplace, I will remember the old man's words and wish him good luck. 
 Question: What did the author's husband feel when she told him what she had done? 
 Options: (A) thankful (B) delighted (C) indifferent (D) disappointed
[A]: B


[Q]: Article: American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations. From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. "With regards to physical levels, we didn't find much of a difference between rich and poor countries," Guthold said, "Growing up in a poor country doesn't necessarily mean kids get more physical activities." The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary. The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn't get enough exercise with girls less active than boys in every country aside from Zambia. Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands. People show deep concern for kids' lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated that urbanization could be a factor as well as easy access to cars and TVs. 
 Question: If you are sedentary, you   _  . 
 Options: (A) are a diligent student spending much time doing homework (B) have at least an hour of exercise outdoors 5 days a week. (C) like watching TV and playing computer games (D) spend longer hours sitting or lying without moving
