Question: I'm taking a test and have to guess the right answer to the question after the article. Article: The flag, the most common symbol of a nation in the modern world, is also one of the most ancient. With a clear symbolic meaning, the flag in the traditional form is still used today to mark buildings, ships and other vehicles related to a country. The national flag as we know it today is in no way a primitive artifact. It is, rather, the product of thousands of years' development. Historians believe that it had two major ancestors, of which the earlier served to show wind direction. Early human beings used very fragile houses and boats. Often strong winds would tear roofs from houses or cause high waves that endangered travelers. People's food supplies were similarly _ . Even after they had learned how to plant grains, they still needed help from nature to ensure good harvests. Therefore they feared and depended on the power of the wind, which could bring warmth from one direction and cold from another. Using a simple piece of cloth tied to the top of a post to tell the direction of the wind was more dependable than earlier methods, such as watching the rising of smoke from a fire. The connection of the flag with heavenly power was therefore reasonable. Early human societies began to fix long pieces of cloth to the tops of totems before carrying them into battle. They believed that the power of the wind would be added to the good wishes of the gods and ancestors represented by the totems themselves. These flags developed very slowly into modern flags. The first known flag of a nation or a ruler was unmarked. The king of China around 1000 B.C. was known to have a white flag carried ahead of him. This practice might have been learned from Egyptians even further in the past, but it was from China that it spread over trade routes through India, then across Arab lands, and finally to Europe, where it met up with the other ancestor of the national flag. Question: The best title for the passage would be " _ ". Options: A: Development of the National Flag B: Power of the National Flag C: Types of Flags D: Uses of Flags
Answer: A

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists have long had it in their mind to make a robot lizard . They began with finding out why a lizard can hang on a wall. They noticed the lizard's toes were unique: They have suckers , which enable it to hang on walls. They, therefore, made a robot with suckers on its hands and feet. The robot could hang on the wall but fell off when crawling. So, they went on researching. 6 years ago, scientists discovered that suckers only were not enough. It is the bristles on each foot that adds friction and static adsorption that makes a lizard move on the smooth wall easily without falling down. Then scientists made great efforts to fix thick bristles to the robot's hands and feet. However, the effect was not satisfactory. The robot still couldn't attach itself firmly to the wall. Scientists got puzzled: How on earth can the lizard crawl on an extremely smooth wall or even on a ceiling without dropping off? An accidental finding inspired them: One day a scientist happened to see an animal attack a lizard and bite off its tail. The lizard broke away from the animal's teeth and threw itself on a wall to escape, only to fall off heavily on the ground. The scientist wondered: Is it the tail that plays an important role in its travelling on the wall? He caught some lizards for an experiment. The result proved his assumption: A tailless lizard has no trouble walking on an ordinary wall but can't on a smooth one. A further study showed the lizard's tail can prevent it falling over backward and, what's more, that the tail acts as an additional leg while one of the lizard's legs leaves the wall, which is always the case while it is walking on the wall. Thus, Tailbot, a super tailed robot, is born. Question: The biggest importance of a lizard's tail lies in _ . Options: A: helping support the body B: serving as another leg C: sticking to the wall D: stopping slipping
Answer:
B
