In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse; in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese kings took pills that contained mercury, believing that it would make them _ , but they died afterwards. Poison has long been an important part in literature and history, and it seems to always be about evil, danger and death. But how much do you really know about poison? An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Feb. 2016, reported The New York Times. The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans. The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad  , the leaky batteries in the trash or the dirty pond water that did it. "Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others." This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment. The blood toxins of vampire bats, for example, can prevent blood from clotting  , which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila... What is the main purpose of the exhibition The Power of Poison? A) To give people more knowledge about poison. B) To teach people how to handle poisonous animals. C) To inform people about which animals are the most poisonous. D) To show how poison has been used for medical treatment.

(Question)
I was very sympathetic with world leaders burdened with resolving conflicts between nations. When my three children were young, in most days it was hard to keep my house from becoming a war zone. It got worse as they grew older. Three years ago, Zack, then 16, couldn't make it through a day without playing tricks on his sisters, Alex and Taryn, then 11 and 9. My husband and I tried to understand his adolescent moodiness. We begged, reasoned, punished, and left heartfelt notes on his bed about how his behavior was hurting our family. His response was a shrug and "I say it because it's true". I even tried telling the girls to fight back. But it was a bad idea. Now I had three kids at war. At wit's end, I poured my heart out to my sister in an e-mail. She wrote back, "Don't e-mail me. E-mail him." Our son was online every day, mailing and instantly messaging his friends. So what if I was within shouting distance? Maybe he would actually hear me this way. There'd be no yelling or door slamming . Zack wouldn't feel under attack. And with a few simple keystrokes, he could respond. Or not. Zack didn't reply for days. When he finally did, his entire message was four words. I expected the worst, but then smiled when I read them, "You are right. I'm sorry." The kids still fought, of course, but Zack scaled back the abuse  . Best of all, I now have an effective way to communicate with not one but three easily annoyed teens. They don't tune me out as much. They don't like to listen to me nag   .Or as Alex says, "You're so much nicer online." All I know is that the house is quiet, and we're talking. In fact, Taryn just instantly messaged me from upstairs. It's time to take her to softball practice. By the first sentence of the passage, the author really means to be  _  . A) humourous B) sympathetic C) serious D) inspiring
(Answer)
A
