Example Input: In the rest of the world, China's supreme sage, Kongfuzi (K'ung Fu-tzu), is better known by the romanized name "Confucius." He was born in 551 b.c. in what is now Shandong Province in eastern China. So profound was his influence that eleven Chinese emperors made pilgrimages to the birthplace of the Great Teacher. You, too, can pay your respects at the vast temple raised on the site of his home in the small town of Qufu (Chufu), and at his tomb in the woods just to the north. The classics of Confucius, while seldom addressing spiritual and metaphysical matters, set standards for social and political conduct that still underlie many of the Chinese ways of doing and perceiving. Confucius laid great stress on the proper and harmonious relationships between ruler and subject, parent and child, teacher and student, the individual and the state. These relationships were deemed to be hierarchical and dictatorial. If the order was disturbed, dire consequences inevitably resulted. The son who disobeyed the father would bring disaster upon himself and his family, just as the emperor who defied the "mandate of heaven" or ignored the good of the empire brought ruin upon the nation. Over the centuries Confucius has suffered more changes of fortune than probably any other philosopher. Honored soon after his death as the greatest of scholars, he was later revered as semi-divine; you can still visit temples to Confucius in many Chinese cities. During the Cultural Revolution (19661976), however, he was denounced as a counter-revolutionary force. It was only after the death of Chairman Mao (1976) and the opening of China to the outside world under more progressive reformers that Confucius, too, was "rehabilitated." Unlike Confucius, about whose life many specific and even colorful details are known, the philosopher Laozi (Lao Tse or Lao-Tzu) is an enigma. Estimates of his date of birth vary by well over a century. One legend even says he taught the young Confucius. Laozi is immortalized by his book of thoughts on man, nature, and the universe, Daodejing ("The Way and Its Power"), which became the major text of China's greatest indigenous religion, Daoism (Taoism). With its emphasis on nature, intuition, the individual, paradox ("The knowledge which is not knowledge"), and the cosmic flow known as "The Way," Daoism became the religion of artists and philosophers. After the death of Confucius, the Zhou Dynasty entered a period of strife known as the "Warring States" period (475221 b.c.). <sep>Where was Kongfuzi born?<sep>Daodejing
Example Output: No

Example Input: When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison. <sep>How can habitats be lost?<sep>killed by invasive tall grass
Example Output: No

Example Input: Heavy wooden shutters dulled the noise of the boisterous gale outside. A thick red curtain hung over the door, and a cheery log fire burnt in the stove. A man and woman sat over it; the man, a tall, repulsive-looking creature, with unkempt hair and matted beard, his age apparently about fifty. The woman looked seventy or more. She too had once been tall, but now old age gave her a withered, witch-like appearance, in spite of her great height. She was dressed in limp, faded garments, with a tattered shawl crossed over her chest, and had a scared, miserable look in her bleared old eyes. There were a few words of explanation from the man who had come home, and then, in gruff but not unkindly tones, he bade Babette be seated, and told his mother to get some supper speedily. She spread a coarse cloth on the wooden table, and when all was ready, lifted a large black saucepan from the stove and turned out a smoking, savoury-looking stew. The youngest son produced a bottle containing the thin acid wine of the country, and another of spirits. As he set them on the table, Babette noticed that across one of his hands, which were much smaller and whiter than those of his brothers, there ran a dull red scar that looked as if he had had a bad cut there. Then they all sat down, excepting the old mother, who busied herself in waiting on them. <sep>Who served the stew?<sep>The man's mother
Example Output:
Yes
