Read the following article and answer the question. Article: "Dad," I say one day, "let's take a trip. Why don't you fly out and meet me?" My father had just retired after 27 years as a manager for IBM. His job filled his day, his thought, his life. While he woke up and took a warm shower, I screamed under a freezing waterfall in Peru. While he tied a tie and put on the same Swiss watch, I rowed a boat across Lake of the Ozarks. My father sees me drifting aimlessly, nothing to show for my 33 years but a passport full of funny stamps. He wants me to settle down, but now I want him to find an adventure. He agrees to travel with me through the national parks. We meet four weeks later in Rapid City. " What is our first stop?" asks my father. "What time is it?" "Still don't have a watch?" Less than an hour away is Mount Rushmore. As he stares up at the four Presidents carved in granite , his mouth and eyes open slowly, like those of a little boy. "Unbelievable," he says, "How was this done?" A film in the information center shows sculptor Gutzon Borglum devoted 14 years to the sculpture and then left the final touches to his son. We stare up and I ask myself, Would I ever devote my life to anything? No directions, no goals. I always used to hear those words in my father's voice. Now I hear them in my own. The next day we're at Yellowstone National Park, where we have a picnic. "Did you ever travel with your dad?" I ask. "Only once," he says. "I never spoke much with my father. We loved each other--but never said it. Whatever he could give me, he gave." _ In Glacier National Park, my father says, "I've never seen water so blue." I have, in several places of the world, I can keep traveling, I realize--- and maybe a regular job won't be as dull as I feared. Weeks after our trip, I call my father. "The photos from the trip are wonderful," he says. "We've got to take another trip like that sometime." I tell him I've decided to settle down, and I'm wearing a watch.

Read the following article and answer the question. Article: 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...
