Example Input: Article: Dear Textual Healing, I would be very interested in your recommendations for any books to help me through a difficult time of my life. At 57, I am feeling a bit lost. I have a wonderful, loving husband and bright, caring teenage daughter but I am lonely and have lost my spark for life. I have always taken care of everyone and managed a career, but, after the death of my father this summer, my difficulties as a child in a terribly abnormal family have come back to me regularly. I have become unfocused and often alone while my husband is away frequently on business and my daughter busy with school and friends. I am seeking the help of a therapist and taking care of myself but I would love to read something to help me "get my groove back" and reengage with life. PC Dear PC, From the letter you've given us about your life, it's no wonder you're feeling a little lost. But before prescribing titles to help you get your groove back, I'd recommend taking a journey into Rebecca Solnit's non-fiction book,A Field Guide to Getting Lost, which is packed with the wisdom of everyone from Pat Barker to Thoreau and Keats. The word lost is rooted in the Old Norse "los", meaning the disbanding of an army. "This origin suggests soldiers falling out of formation to go home, ceasing fighting with the wide world. I worry now that many people never disband their armies, never go beyond what they know," Solnit writes. So instead of fearing that lost feeling, try seeing its potential for discovery. Explorers, remember, are always lost simply because they're forever someplace new. "Leave the door open for the unknown, the door into the dark," Solnit advises. "That's where the most important things come from, where you yourself came from, and where you will go." For something that asks a little less of the reader while still giving plenty in return, try a dose (--) of Anne Tyler, the beloved creator of numerous heroes whose serious conditions will move anyone who finds themselves in a midlife difficult situation. One such character is 53-year-old Rebecca Davitch, the heroine ofBack When We Were Grownups. Like you, she's combined marriage and motherhood with a career but suddenly finds herself feeling lonely in her own home. Could it be, she wonders, that she's "turned into the wrong person"? Don't be fooled by the way this novel ambles along -- as Rebecca revisits youthful ambitions and the college boyfriend she abandoned, it asks some heart-rending questions before arriving at a place of graceful, joyous acceptance. Along similar lines, I'm also going to recommendThe Unlikely Pilgrimage of Harold Fryby Rachel Joyce. Its hero is 65 when he learns that a former colleague sick. On his way to post her a note,he decides instead to visit her -- on foot, from his home in deepest Devon to England's northernmost town, more than 600 miles away. You don't manage that without focus! It's a journey to a holy place that will take him 87 days to complete, during which he considers his childhood, marriage and relationship with his son, and becomes an accidental media sensation . By the time he reaches his destination, you'll feel anything but tired. Finally, Ruth Ozeki's novelA Tale for the Time Beingwill charm the missing spark back into your life. Combining the diary of a sad Tokyo teenager with the story of the middle-aged novelist who finds it, washed ashore on a remote island off the coast of British Columbia, it's a beautiful illustration of how our lives touch -- and are touched by -- others in ways we mightn't even be aware of. This "Man Booker Prize" finalist has plenty to teach about Zen Buddhism, and unless you happen to live in one of its settings, it provides a bracing change of scene, too. One other suggestion: books, as we all know, make great companions but that doesn't mean they can't be enjoyed in the company of others. If you find yourself home alone, why not slip one into your back pack and head out to a favourite cafe.

Example Input: 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

Example Input: Article: Farm-raised pigs are dirty, smelly animals that get no respect. They're also an environmental hazard. Their manure contains phosphorus ,which, when it rains, runs off into lakes and rivers, consuming oxygen, killing fish, stimulating algae overgrowth and emitting greenhouse gases. Doing away with the pig is not an option. Pigs provide more dietary protein, more cheaply, to more people than any other animal. Northern Europe still maintains the highest pig-to-human ratio in the world (2-1 in Denmark), but East Asia is catching up. During the 1990s, pork production doubled in Vietnam and grew by 70 percent in China--along densely populated coastlines, pig density exceeds 100 animals per square kilometer. The resulting pollution is "threatening fragile coastal marine habitats including mangroves ,coral reefs and sea grasses ,"according to a report released in February by the Food and Agriculture Organization of the United Nations. As it turns out, there is a solution to the pig problem, but it requires a change of mind-set among environmentalists and the public. Two Canadian scientists have created a pig whose manure doesn't contain very much phosphorus at all. If this variety of pig were adopted widely, It could greatly reduce a major source of pollution. But the Enviropig, as they call it, is the product of genetic modification--which is anathema to many Westerners. The Enviropig is one of many new technologies that are putting environmentalists and organic-food supporters in _ : should they remain categorically opposed to genetically modified (GM)foods even at the expense of the environment? Elsewhere, trees grown for paper could be made amenable to much more efficient processing, reducing both energy usage and toxic chemical bleach in waste water from paper mills. The most significant GM applications will be ones that help lessen the problem of agriculture , which accounts for 38percent of the world's landmass and is crowding out natural ecosystems and species habitats. Chances are, farmers will continue to grow their polluting organic pork, their allergenic organic soy and their neurotoxin sprayed organic apples. Worse still, they will make sure that no one else gets a choice in the matter of improving the conditions of life on earth--unless, that is, others rise up and demand an alternative.
Question: Which of the following statements is TRUE?
Options: (A) Pigs bring more destruction than benefit to human beings. (B) No other countries have the higher percentage of pig-to-human than East Asia. (C) The pork production has increased to 70% in China. (D) The pollution brought by pigs is a killer to the creature of the sea.
Asnwer: D
