Write a multi-choice question for the following article, with the given choices and answer: Article: As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (, ) in science. Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry . These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute. Of course, scientists cannot answer all of our questions. If we ask, "Why does the ocean water taste salty?" Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , "What happens to the salt in the ocean? The ocean does not get saltier every year." Scientists are not sure about the answer to this question. We know a lot about our world, but there are still many answers that... Options: A People are curious in the same way. B People in different countries are interested in different things. C Men and women are curious about different things. D People of different ages are interested in different things Answer: D People of different ages are interested in different things Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: The painter Georgia O'keeffe was born in Wisconsin in 1887 and grew up on her family's farm. At seventeen she decided she wanted to be an artist and left the farm for schools in Chicago and New York, but she never lost her bond with the land. Like most painters, O'Keeffe painted the things that were most important to her, and nearly all her works are simplified portrayals of nature. O'Keeffe became famous when her paintings were discovered and exhibited in New York by the photographer Levered Stieglitz, whom she married in 1924. During a visit to New York in 1929, O'Keeffe was so moved by the bleak landscape and broad skies of the Western desert that she began to paint its images. Cows' skulls and other bleached bones found in the desert figured prominently in her paintings. When her husband died in 1946, she moved to New Mexico permanently and used the horizon lines of the desert, colorful flowers, rocks, barren hills, and the sky as subjects for her paintings. Although O'Keeffe painted her best known works in the 1920's, 1930's and 1940's, she continued to produce tributes(, ) to the Western desert until her death in 1986. O'Keeffe is widely considered to have been a pioneering American modernist painter. While most early modern American artists were strongly influenced by European art, O'Keeffe's position was more independent. She established her own vision and preferred to view her painting as a private endeavor. Almost from the beginning, her work was more indentifiably American than that of her contemporaries in its simplified and idealized treatment of color, light, space, and natural forms. Options: A O'Keeffe was a distinctive modern American painter. B O'Keeffe was the best painter of her generation. C O'Keeffe liked to paint only what was familiar to her. D O'Keeffe used colors and shapes that are too reduced and simple. Answer: A O'Keeffe was a distinctive modern American painter. Question:
