Read the following article and select the best answer. Article: There is a lot of talk these days about how kids should be interested in science. Here's an area of science for everyone, and these cool new books might inspire you to discover your inner scientist. Scaly Spotted Feathered Frilled by Catherine Thimmesh, 58 pages, ages 9-12 Seeing a picture or a model of a dinosaur, do you wonder how anybody knows what they look like? After all, nobody has seen a living dinosaur. This book explains how scientists and artists work together to re-create dinosaurs. As scientific discoveries have been made, the models have changed. Scientific tests may one day expose what a dinosaur's coloring was, but now artists have to use their imagination to determine how these huge creatures looked. Beyond the Solar System by Mary Kay Carson, 128 pages, ages 10-13 This book takes readers back to the beginnings of space exploration--thousands of years ago, when people began star observation--and forward to today's search for planets in distant parts of the Milky Way. Along with history lessons, readers get 21 activities, such as making a black hole and creating a model of Albert Einstein's universe using a T-shirt. The activities are perfect for cold winter days. Ultimate Bugopedia by Darlyne Murawski and Nancy Honovich, 272 pages, ages 7 and older If you're always on the lookout for butterflies, this book is for you. Hundreds of color photos of common and unusual insects fill this hardcover. There are fascinating stories related to the photos. For example, do you know an insect feeds on the tears of Asian cattle? There's a question-and-answer section with an insect scientist and advice on how to help preserve endangered insects. Journey Into the Invisible by Christine Schlitt, 80 pages, ages 9-12 If you use a magnifying glass, you know a leaf looks quite different. This book explains what microscopes do and then shows what happens to things around the house when watched with this amazing scientific tool. The bacteria in your mouth, when magnified 20,000 times, look a bit like swimming pool...

(Question)
Read the following article and select the best answer. Article: Legend has it that sometime toward the end of the Civil War (1861 - 1865) a government train carrying oxen was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived? The answer lay in a resource that unknowing Americans had trampled underfoot in their haste to cross the "Great American Desert" to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the west, that familiar blue joint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them superior to the cultivated eastern grasses. Variously known as buffalo grass, not only were they immune to drought, but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground. When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year, for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses. Question: What does the passage mainly discuss? - Western migration after the Civil War. - The raising of cattle. - The climate of the westernprefix = st1 /United States. - A type of wild vegetation.
(Answer)
A type of wild vegetation.

Ans: You should frequently put on sunscreen while playing outdoors.

Ques:Read the following article and select the best answer. Article: Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate . As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi. Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career. Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations. Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them. Aided by computers, Hoffmann was able to _ a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value. Question: Why was Ronald Hoffman awarded the 1981 Nobel Prize for chemistry? - He established rules to predict chemical reactions . - He succeeded applying computer science to chemistry research. - He shared what he had achieved with another scientist named Fukui Kenichi. - He succeeded in both chemistry and computer researches.

Ans:
He succeeded applying computer science to chemistry research.
