[Q]: Oh no! Your younger sister just mixed up all of your LEGO parts. Now you have to put them all back into the original categories. How will you do this? You sort them by size and shape until they are each back into their specific place in the tray. What do you think you could have called the mess your younger sister created? Thats right, it is a mixture. Fortunately, it was a physical change and she just made a simple mixture. You are able to separate them back into order. Its a good thing she did not toss them into the fireplace. That would have caused a chemical change as they all melted together. If your LEGOs were melted, you would be out of luck for building that next big project. <sep>Why do you have to sort your LEGOs and put them in the tray?<sep>Your sister mixed them together
[A]: Yes


[Q]: Hundreds of thousands of years before China was to become the world's longest-running civilization, the prologue was enacted by means of the flicker of a carefully tended fire. Peking Man, a forebear of Homo sapiens, achieved a mastery of fire. We might call it the first Chinese invention. Not that he devised flint and steel, matches, or any other way of creating fire. Peking Man simply learned how to capture flame, perhaps from a forest fire, and keep it alight. He thus enjoyed two revolutionary luxuries: light and heat. Technologically and sociologically, it was a phenomenal breakthrough: with fire, communities could live year 'round in one cave, in which cooking and even smelting could be pursued. And so, by 600,000 b.c., about 50 km (31 miles) southwest of present-day Beijing, the ancestors of mankind were ready to settle down. Several hundred thousand years later, when Marco Polo reached the capital of China, he was astonished by a further development in fire technology. The Chinese, he announced, used black stones dug out of mountains as fuel. Europeans did not yet have a word for "coal," nor had they discovered a use for it. The First Dynasty The confluence of mythology and history in China took place around 4,000 years ago during what is referred to as the Xia (Hsia) Dynasty. This was still the Stone Age, but the people are thought to have made silk from thread produced by the worms they cultivated on the leaves of their mulberry trees. And written language (which evolved as early as 4,500 to 5,000 years ago) was already in use, originally by oracles and then by official scribes — China's first scholars. During the second of the quasi-legendary dynasties, the Shang (from about the 16th to 11th centuries b.c.), the Chinese developed an interest in art. Careful geometric designs as well as dragon and bird motifs adorned bowls and implements. And with the arrival of the Bronze Age, the Chinese created bronze vessels of such beauty and originality that, until modern times, archaeologists refused to believe they were cast 3,000 years ago. The Shang Dynasty gave rise to the concept of one Chinese nation under one government. <sep>During the Shang Dynasty, the Chinese developed an interest in what type of designs?<sep>Bowls
[A]: No


[Q]: At the age of eighteen there came a change in Poe's life. Until then he had been a petted child in a wealthy family. Mr. Allan did not have that affection for him which Mrs. Allan had. He did not understand the boy's peculiar and erratic nature, and was particularly displeased when he found that Edgar had run into debt at college. There was an angry scene between the two, and Edgar was told that he must leave the university and go into the counting-room. It appears that he made some attempt to tie himself down to figures and accounts and business routine; but as he had not been brought up to this kind of life, he soon tired of it, and decided to go into the world to seek his own fortune. He went to Boston, where he published a volume of poetry. In the preface to this volume, Poe says that the poems were written before he was fourteen. Though this may not be strictly true, there is little doubt that some of them were. While he was still at school he had collected enough of his poems to make a volume, and Mr. Allan had taken them up to the master of the English and Classical School to get his advice about publishing them. This gentleman advised against it on the ground that it would make Edgar conceited,--a fault from which he was already suffering. As soon as he was free to do as he pleased, therefore, it was natural that he should rewrite his poems and publish them. <sep>Describe a scene that illustrates the differences Poe's parents had in their affection for him.<sep>There was an angry scene between the two,
[A]:
No
