[EX Q]: Article: At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot. There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can't fly into the air from the ground. Their wings don't produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can't run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight. During the hours when most enemies are active, bats gather where few animals would think to look and most can't reach. This allows them to disappear from the world until night comes again. There's also little competition for these resting spots, as other flying animals don't have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract  several muscles in your arm, which are connected to your fingers by tendons ;as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat's talons  close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn't have to do anything to hang upside down. 
 Answer: they can't start to fly from the ground directly

[EX Q]: Article: The world's most famous awards, the Nobel Prizes, are given for achievements that benefit humankind. Ironically they are named for a 19thcentury scientist who invented powerful explosives that came to be used as weapons of war. Alfred Nobel, a Swedish-born chemist who died in 1896, was known by some as "The Mad Scientist," and by others as "The Merchant of Death." He was really pacifist, who at one time believed that his explosives could end warfare. Later, he realized that he was wrong. "High explosives will not stop men from war," he wrote. "Nobody will benefit from my inventions except manufacturers of war materials, some generals, and diplomats." Nobel was born in Sweden in 1833. His father was an architect and inventor who moved to Russia. With only one year formal schooling, Nobel became a chemist and inventor by the age of 16. He was also excellent in languages, speaking English, Russian, German, and French in addition to Swedish. He wrote poetry. His study of explosives began with manufacturing liquid nitroglycerin for use in mining and construction. But in 1864, the factory blew up, killing his youngest brother and four others. He then discovered that liquid nitroglycerin could be dried and handled safely to be a mixture, which can explode. He called the mixture dynamite, after the Greek word dynamis, meaning "power." He then perfected a more powerful form of dynamite that made him a multimillionaire. When he died, his fortune was about $9 million. Nobel never married, and he left his fortune to what has since become known as the Nobel Prizes. The money is invested and the interest is given out every year as prizes for the most important work in six fields: Physics, Chemistry, Physiology or Medicine, Literature, and Peace. Nobel Prize winners receive money, a gold medal, and a diploma. Prizes were first awarded in 1901, and the list of Nobel laureates  contains many well-known names: Albert Einstein in Physics, Marie Curie in Chemistry, Toni Morrison and William Faulkner in Literature, Martin Luther King, Jr., for Peace.
