I'm taking a test and have to guess the right answer to the question after the article. Article: Nails in the Fence There once was a little boy who had a bad temper . His father gave him a bag of nails and told him that every time he lost his temper, he must hammer a nail into the back of the fence. The first day he had driven 37 nails into the fence. Over the next few weeks, as he learned to control his anger, the number of nails hammered daily gradually _ . He discovered it was easier to hold his temper than to drive those nails into fence. Finally the day came when the boy didn't lose his temper at all. He told his father about it and the father suggested that now pull out one nail for each day that he was able to hold his temper. The days passed and the young boy was finally able to tell his father that all the nails were gone. The father took his son by the hand and led him to the fence. He said," You have done well, my son, but look at the holes in the fence. The fence will never be the same. When you say thing in anger, they have a scar just like these holes. You can put a knife in a man and draw it out. It won't matter how many times you say 'I am sorry ', the wound is still there. A verbal wound is as bad as physical one." The little boy then understood how powerful his words were. He looked at his father and said " I hope you can forgive me ,father, for the holes I put in you." "of course I can," said the father. Question: When you say something with anger, they will leave a scar just as you put a nail in and then draw it out. It means _ . Options: A: you shouldn't put a nail in the fence B: if you put a nail into the fence, you shouldn't draw it out C: it will leave a scar when you draw a nail out D: you will hurt somebody when you lose your temper.

I'm taking a test and have to guess the right answer to the question after the article. Article: Researchers Jose Cordova and Erich Astudillo have discovered a new molecule that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay . The new molecule they call "Keep 32" has been found to kill the bacteria. The two have applied for a patent on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep _ at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year. The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they've discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey's. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved. Over the years many products have _ with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks. Question: This passage mainly tells us that _ . Options: A: many health problems are closely connected to tooth decay B: the discovery of a new molecule will greatly benefit health care C: two researchers are discussing their patent with companies D: researchers discover a molecule that can kill tooth decay-causing bacteria

I'm taking a test and have to guess the right answer to the question after the article. Article: Sally Donovan is cooking when a paper plane flies across the kitchen and lands at her feet. She picks it up, unfolds it and finds a child's sketch of a tear-stained face with a speech bubble saying: "I'm sorry I was naughty--I'm a bad person." Sally, 42, draws a big smiley face on the back of the paper with "I love you, Rose, and we're always going to look after you." Then she folds it up and launches the plane back into the living room where her nine-year-old daughter is watching TV with brother Jamie, 13 and dad Rod, 40. Jamie often makes pictures for his parents too--like the one showing a swift river with them on one side and him trapped on the other side. It's one of the many unusual ways that Sally and Rob have learned to communicate emotionally with their abused children in an astonishing eight-year journey of hope, healing and love. Jamie was just four and half--sister Rose one when they were adopted by the Donovans in 2005. The youngsters had been taken from their natural mother and placed in foster care after a series of cruelty and neglect. They were left alone, hungry, and witnessed home violence on a regular basis. Sally and Rob spent three years trying for a baby before deciding to adopt, and were well aware of the youngsters' poor background. But they were still unprepared for raising a child permanently scared by abuse or the lack of support on offer. But now Sally has written a brilliant and heart-touching account of their family struggle in a book called "No Matter What". Sally said: "These kids come to you with a story that what happened to them was their fault--because they are bad and unlovable. To show them they are loveable and none of it was their fault takes a lot of time. They both still say "I'm bad". Jamie is less stuck on it now but whenever life deals him a knock, he will fall back into 'that happened because I am stupid, I'm rubbish, I'm bad'." Sally's book is humorous, heart-touching and so wildly honest that academics, charity bosses, parents and adoptees are praising it as... Question: Why did the two adopted children still say "I'm bad" ? Options: A: They know clearly they are not lovable enough. B: They often put the situation in an embarrassment. C: What they suffered rooted deep in their minds. D: They are honest of what they have done.
