Ques: Article: (2013*,B)On a sunny day last August,Tim heard some shouting.Looking out to the sea carefully,he saw a couple of kids in a rowboat were being pulled out to sea. Two 12yearold boys,Christian and Jack,rowed out a boat to search for a football.Once they'd rowed beyond the calm waters,a beach umbrella tied to the boat caught the wind and pulled the boat into open water.The pair panicked and tried to row back to shore.But they were no match for _ and the boat was out of control. Tim knew it would soon be swallowed by the waves. "Everything went quiet in my head,"Tim recalls ."I was trying to figure out how to swim to the boys in a straight line." Tim took off his clothes and jumped into the water.Every 500 yards or so,he raised his head to judge his progress."At one point,I considered turning back," he says."I wondered if I was putting my life at risk."After 30 minutes of struggling,he was close enough to yell to the boys,"Take down the umbrella!" Christian made much effort to take down the umbrella.Then Tim was able to catch up and climb aboard the boat.He took over rowing,but the waves were almost too strong for him. "Let's aim for the pier ,"Jack said.Tim turned the boat toward it.Soon afterward,waves crashed over the boat,and it began to sink."Can you guys swim?"he cried."A little bit,"the boys said. Once they were in the water,Tim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys'faces. "Are we almost there?"they asked again and again."Yes,"Tim told them each time. After 30 minutes,they reached the pier. Question: Why did the two boys go to the sea? Yes or no, is the answer "To get back their football."?
Ans: No

Ques: Article: The speed of light is often called a"constant ". New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is"very impressive work", Robert Boyd toldScienceNews.An optical physicist at the University of Rochester in New York, he did not work on the study. He speaks of the new finding:"It's the sort of thing that's so obvious; you wonder why you didn't think of it first." Light travels as particles and as waves. Photons are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters (almost 1 billion feet) in a single second. That's fast enough to get to the moon and back in about 2.6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at a peak speed. That would seem to make sense. After all, a vacuum is a space with nothing in it to slow light down. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to slowing light is to change the shape of a light wave. Padgett described how they did this in a paper published online January 22 inScience. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light on a point, for instance. The second photon passed through one device that changed the shape of its waveand another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several... Question: The passage mainly tells . Yes or no, is the answer "light can be slowed down in a vacuum"?
Ans: No

Ques: Article: Guide to Stockholm University Library Our library offers different types of studying places and provides a good studying environment. Zones The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work. Computers You can use your own computer to connect to the wi-fi specially prepared for notebook computers; you can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor. Group-study Places If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2-3 people and others can hold up to 6-8 people. All rooms are marked on the library maps. There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week. Storage of study material The library has lockers for students to store course literature. When you have obtained at least 40 credits , you may rent a locker and pay 400 SEK for a year's rental period. Rules to be followed Mobile phone conversations are not permitted anywhere in the library. Keep your phone on silent as if you were in a lecture and exit the library if you need to receive calls. Please note that food and fruit are forbidden in the library, but you are allowed to have drinks and sweets with you. Question: The library's upper floor is mainly for students to _ . Yes or no, is the answer "read in a quiet place"?
Ans: No

Ques: Article: An ATM that spits out cupcakes instead of cash is now filling a popular demand in the American market:late-night desire for freshly baked sweets. In six cities across the country, sugar addicts can now purchase a cupcake for $4.25 from an automatic machine 24 hours every day.The freshly baked goods are made by the California-based cupcake shop Sprinkles. The idea came to the company's co-founders Candace and Charles Nelson when Candace was pregnant with their first child. Candace thought it was ridiculous that she owned cupcake bakeries aad couldn't get a freshly baked treat at an unusual hour.That desire inspired the company's first cupcake ATM in Beverly Hills,Calif.in 2012. Charles said each ATM serves about l,000 cupcakes per day.The machine is so popular that when it appeared in Manhattan, customers were lined up around the block to use _ Yet,inventing the first cupcake ATM was not as easy as convincing customers to use it.When the Nelsons started defigning the machine,they quickly realized nothing existed that could give a fully unbroken cupcake to a customer.The company had to partner with a European firm to develop the technology that could deliver a cupcake without dropping it several feet like a typical machine.After going through a seeond development cycle with the product, the ATMs can now satisfy tlle demand of growing customers and even make as many as four cupcakes at a time. In terms of the company, the-machine allows Sprinkles to do the impossible:increase hours of operation without raising costs.Now the company can sell cupcakes around the clock through the ATM without paying employees. Now the company is partnering with a Middle Eastern company to open 34 new locations abroad. Question: What's the purpose of the text? Yes or no, is the answer "To introduce a newly-invented cupcake ATM."?
Ans:
Yes
