Read the following article and select the best answer. Article: The world's biggest Internet search engine, Google, has proven once again to be King of the Web. Users can download "Google Wi-Fi" software and then enjoy free Wi-Fi service available in some US cities since last Tuesday. Wi-Fi is short for "Wireless Fidelity" . It allows laptop computers and personal digital assistants to the Internet at high speed by radio signal. A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network's access points. The place covered by one or several access points is called a hotspot. Google has already set up two "hotspots" in the US city of San Francisco which provide a free Wi-Fi service. The Wi-Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks. Wi-Fi is still limited to a few cities, where there are "hotspots". But its capability of sending information has already done better than that of the mobile phone network, even that of 3G(Third Generation Telecommunication Technology). Some scientists have started to call Wi-Fi 4G. In addition to a high speed Internet connection, Wi-Fi has other advantages compared to mobile phones. Wi-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don't need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all. Question: Wi-Fi is not available in cities without _ . - a computer - a radio - a cell phone - a hotspot
a hotspot

(Question)
Read the following article and select the best answer. Article: "There's going to be one less boy in the room!" The words rang in my ears as the criminal pointed his gun against my head. The floodgates opened and tears ran down my face. No one in the courtroom moved. Everyone was held silent with fear. A few seconds passed and the criminal put down his gun, turning his back on me. "Cut!" the director shouted with joy. One take! We had done the scene in just one take. Then all the people who acted in the film went off for lunch. I got my food and joined them, and the criminal, who had moments before been so scary, took his seat beside me and told us many funny jokes. A table of adults surrounded me, but I was never uncomfortable talking with strangers. I worked with these people and they worked with me. We talked, we laughed, we got to know each other and sometimes we became friends. At the end of the day we all went our separate ways, but we had been drawn close by working together to make this play. After the show was broadcast, my friends asked if I had been scared of the criminal. At first this sounded funny. He was, after all, a kind and intelligent man. Then I realized that they didn't see that side of him. Television and films are about creating an alternate life that appears real even if for a while. We had been successful in doing that. Even my friends, who knew the real me, were drawn in the make-believe world of our story. Acting has helped me to feel comfortable in my own skin and in communicating with others. I feel relaxed during interviews and when leadership opportunities come. Change is not threatening to me, and I am grateful for the chance to learn and to grow in knowledge and experience in my life. Question: It can be inferred from the passage that_. - the author felt lucky to play in the film - it wasn't the first time that the author had acted in films - the author's friends encouraged him to act in films - the author had a successful career because of this film
(Answer)
the author felt lucky to play in the film

Ques: Read the following article and select the best answer. Article: More than half of teachers in a UK survey said they thought _ from the Internet is a problem. Some students who steal essays wholly from the Web, they said, are so lazy they don't even bother to take the ads off the cut-and-pasted text. 58 percent of the teachers interviewed in the Association of Teachers and Lectures(ALT) questionnaire had come across plagiarism among their pupils. Gill Bullen from Itchen College in Southampton, for example, said pieces handed in by two students were the same and significantly better than either of them could have done." "Not only that, the essays given in didn't quite answer the title question I had set." A teacher from Leeds said, " I had one piece of work so obviously 'cut and pasted' that it still contained ads from the Web page" Connie Robinson from Stockton Riverside College, Stockton, said, " With less able students, it is easy to spot plagiarism as the writing style changes mid-assignment, but with more able students, it is sometimes necessary for teachers to carry out Internet research to find out the source of the plagiarism." Mary Bousted, general secretary of the ALT, said, "Teachers are struggling under a mountain of cut-and-pasting to spot whether work was the student's own or plagiarism." She called for strong policies to oppose plagiarism, and asked for help from the government in providing resources and techniques to delete cheats. Question: According to Para 2 some students are so lazy that they don't _ . - bother to remove the ads - want to steal the whole essay - check the mistakes on the Internet - bother to do the work of cutting and pasting
Ans: bother to remove the ads

Question: Read the following article and select the best answer. Article: Ocean animals have been getting bigger over the last half-billion years. Not a little bigger. Not even a lot bigger. They have _ gigantically, scientists now conclude. Their new finding lends support for something known as "Cope's rule." It holds that animals tend to evolve into species that are much larger than their distant ancestors. This hypothesis takes its name from the 19thcentury paleontologist Edward Drinker Cope. While studying fossils , he was the first to notice this trend. Noel Heim is a paleontologist at Stanford University in Palo Alto, Calif. He also is a co-author of the new study. His team compared the body size of animals between the Cambrian Period and modern times. This was a span of 542 million years. The animals studied included species from more than 17,000 genera. They ranged from ancient trilobites, plesiosaurs (extinct reptiles with a long neck and flippers) and many less familiar creatures to today's whales and clams. Ocean animals today are an average of 150 times larger than they were during the Cambrian, Heim's group reports. The smallest animals alive today -- tiny crustaceans called ostracods -- are only about one-tenth the size of the Cambrian's tiniest animals. But today's largest ocean animals -- whales -- are more than 100,000 times bigger than the biggest in the Cambrian. "Classes of animals that were already big ... tended to live longer," Heim says. They also tended to change more than classes of animals that were small did. The size gains in ocean animals are much larger than would be expected by chance, saysJonathan Payne. He's a co-author who also works at Stanford. The scientists don't know what drives the trend. One possibility is an arms race between predators and prey. The idea here is that larger animals are less likely to become some other animals' meal. Another possibility has to do with oxygen. Land animals evolved from species that started in the ocean. Some of these land animals eventually returned to the ocean. And they kept the ability to breathe... Question: The ocean animals' change in size _ . - is determined by environment - cannot be predicted by any factor - is fully explained by the new study - relates to the size of their ancestors
Answer:
relates to the size of their ancestors
