Question: Article: Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4. 5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust , eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is l. 3 billion years earlier than previous ones. Not long before 3. 8 billion years ago, lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock. To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of plate under the ocean, beginning around 3.8 billion years ago. "It's a fantastic case of solving a jigsaw puzzle ,"says one of the researchers. He notes that the puzzle was "a very difficult one because these rocks are all very old and have been badly ruined".
Question: What can we infer from the text?
Options: (A) The shapes of continents and oceans changed slowly. (B) The Earth's crust started shifting l.3 billion years ago. (C) The crust began to shift when the Earth was hot. (D) The hit from small planets made the Earth cool.
Asnwer: B

Answer: No

Question: Article: DIY sailor Owen Warboys has finally launched his homemade boat -- after spending nearly 30 years building it in his mum's garden. Owen, 66, a retired engineer from Hordle, New Milton, Hants, first started work on the 40ft--long boat in 1982 because he could not afford to buy his own. He told mum Edith that it would only take five years but after suffering "a few problems" it lasted nearly three decades. When he finally finished, he was left with the head-scratching task of getting the 18-tonne boat out of the back garden. After some time he found a way. A huge crane was brought in to carefully raise it 40ft in the air over his mother's house and onto a lorry. It was then driven to the seaside and, to Owen's delight, it floated and showed no signs of leaking when lowered into the water. Now, 28 years after he first started, Owen is at last preparing to set sail in his beloved boat, Wight Dolphin, with his long-suffering wife Anne. Owen said, "I am so relieved that it's finished. There were times when I thought it would never end but I'm the sort of person who likes to finish something once I've started." At first he persuaded his mum to let him do it in her garden and started taking in sheets of steel and pieces of wood. "My mother was happy for me to build it at her house but only bacause I told her it would only take five years."
Question: Why did Owen decide to make his own boat by himself?
Options: (A) He wanted to kill time after his retirement (B) He wished to set a new world record (C) He didn't have enough money to buy a boat (D) He had a hobby of making things by hand
Asnwer: C

Answer: Yes

Question: Article: Besides news reports that tend to focus on war or election, Americans generally don't hear much about people in other countries. One reason may be that very little foreign-language literature is translated into English. In the United States, just a few of the titles, mainly translations of foreign novels, short stories, or poetry, make it into English. However, a number of efforts have taken root to try to bring more global literature to US audiences. Ks5u The online magazine of international literature, Words Without Borders, was founded by Bard College in Annandale-on-Hudson, N.Y. The nonprofit site, now in its fifth year, offers modern writing from places such as Argentina, China and Italy, often for the first time in English. It gets about 200,000 page views per month and counts roughly 8,000 subscribers , more than one-quarter of whom live in the US. "There's a wave of interest right now," says Jill Schoolman, publisher of Archipelago Books, a small nonprofit press in Brooklyn, N.Y., opened in 2003 to publish world literature in translation only. "People are hungry for ideas from other countries." Rainmaker Translations, a Las Vegas-based nonprofit, was formed two years ago to support the publication of more top-quality global writing here in the US. They put out their first three titles, translated from Arabic, Chinese and Russian, in the spring of 2006 and plan to aid up to four more in the coming year. In March, the Center for the Art of Translation, a nonprofit started in 1994 in San Francisco, will publish Two Lines World Library, focused on writing from some particular areas published over the last several decades. Dalkey Archive Press, a century-old nonprofit publisher in Champaign, Illinois, has upped the number of translations on its publication list since 2003, from 25 percent to nearly 80 percent. In recent years, more nonprofits have applied to the National Endowment for the Arts for help to publish literary translations. The agency is also trying to increase the availability of translated prose and poetry in the US, such as publishing partnerships with foreign governments.
Question: The main purpose in founding the magazine Words Without Borders is _ .
Options: (A) to compete for page views and subscribers online (B) to get American literature better known to the world (C) to help advance nonprofit world literature translation (D) to introduce more world literature to readers in the US
