Ques:Read the article and select the best answer. Article: Chilean rescued miner Edison Pena ran the New York City Marathon on November 7th , less than a month after he was rescued from a collapsed   mine that trapped him and the other 32 miners for 69 days. Pena ran 10 km daily through the mine's tunnels   to beat the anxiety, wearing cut-down boots until rescuers sent him a pair of sports shoes through a narrow hole that served as the miners' "lifeline" to the surface. "When I ran in the darkness, I was running for life," Pena told a news conference in New York. "I was running to show that I wasn't just waiting around. I also wanted God to see that I really wanted to live." The miners were discovered alive on August 22---17 days after the mine collapsed, but it took many more days for rescuers to dig a hole big enough to bring them out.        The New York Road Runners, which organizes the marathon, had invited Edison Pena to the event after hearing his story. They thought he could ride in the lead vehicle or hold the finish line tape, but Pena said last week he did not want to watch, he wanted to run. "I was very eager to take on this big challenge," he said. "I wanted to show the world I could run." He hoped to run the 26.2-mile race in about six hours. "I have a knee injury, but I am eager to cross the finish line," he said.        An Elvis Presley fan who asked rescuers to send the singer's music down into the mine, Pena broke into song at the news conference with the Presley hit Return to Sender.  On the morning of November 7th, Pena, known as "the runner" by fellow miners trapped with him, set out to cover the course along with thousands of other runners and completed the race in five hours and 40 minutes. Question: During the rescue of the Chilean trapped miners, the digging of the escape hole lasted about   _  . Options: A: 17 days B: 22 days C: 52 days D: 69 days

Ques:Read the article and select the best answer. Article: Howling is a behavior commonly observed among a wolf pack . As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There are different explanations of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bond better together. It's almost as if howling together helps the pack stay together, perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behavior.     Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be "punished" for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status among its members? --Why do wolves howl for sure? What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering. Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of "roll call" where wolves all howl together to report their presence. Question: What is the possible similarity between wolves' howling together and human's singing in chorus? Options: A: The act of calling each other. B: The sense of achievement. C: The act of hunting for something. D: The sense of belonging to a group.

Ans:D

Ques:Read the article and select the best answer. Article: How Do Animals Catch their ZZZ's ? Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off, and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping. Gorillas like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed. Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don't use a nest. They just lock their feet around a branch and hang on. A special tendon in their legs is automatically tight when they are at rest, so they won't let go and fall. Dolphins live underwater, but must come to the surface to breathe. Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this, lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open. Question: What does the writer intend to tell us? Options: A: The cleverest animal is the gorilla because it can make beds. B: Differences in habitat can lead to different living habits. C: The ways animals catch their ZZZ's are pretty much the same. D: In order to protect themselves most animals choose not to sleep

Ques:Read the article and select the best answer. Article: Etymology, the study of words and word roots, may sound like the kind of thing done by boring librarians in small, dusty rooms.Yet etymologists actually have a uniquely interesting job.They are in many ways just like archaeologists   digging up the physical history of people and events.The special aspect of etymology is that it digs up history, so to speak, through the words and phrases that are left behind. The English language, in particular, is a great field to explore history through words. As a language, English has an extraordinary number of words.This is partly due to its ability to adapt foreign words so readily.For example, "English" words such as kindergarten (from German), croissant (from French), and cheetah (from Hindi) have become part of the language with little or no change from their original sounds and spellings. So English-language etymologists have a vast world of words to explore. Another enjoyable thing about etymology for most word experts is solving word mysteries .No, etymologists do not go around solving murders, like the great detective Sherlock Holmes.What these word experts solve are mysterious origins of some of our most common words One of the biggest questions English language experts have _ is how English came to have the phrase OK.Though it is one of the most commonly used expressions, its exact beginning is a puzzle even to this day.Even its spelling is not entirely consistent-unless you spell it Okay, it is hard even to call it a word. Etymologists have been able to narrow OK's origin down to a likely, although not certain, source .It became widely used around the time of Martin Van Buren's run for president in 1840. His nickname was Old Kinderhook. What troubles word experts about this explanation is that the phrase appeared in some newspapers before Van Buren became well known.It is likely that Van Buren could be called its primary source Etymologists will doubtlessly keep searching for the initial source.However, it is clear that OK's popularity and reputation have... Question: What is the main purpose of the passage? Options: A: To present the history of English words. B: To explain the procedure of an etymologist's job. C: To introduce the pleasure of the study of words and word roots. D: To teach readers how to distinguish English and non-English words
