Problem:  We waited for half an hour, watching the smoke curling over the house, and then, judging that the Indians had made off for fear of being ambushed, we crossed the clearing.  It took but a glance to read the story.  The women had been washing by the little brook before the cabin, with the children playing about them, when the Indians had come up and with a single volley killed them all except the child we had heard crying.  They had swooped down upon their victims, torn the scalps from their heads, looted the house, and set fire to it.  We dragged out the body of the woman which had been thrown within, in the hope that a spark of life might yet remain, but she was quite dead.  Beneath the warrior Spiltdorph had shot we found the child.  It was a boy of some six or seven years, and so covered with blood that it seemed it must be dead.  But we stripped it and washed it in the brook, and found no wounds upon it except in the head, where it had been struck with a hatchet before its scalp had been stripped off.  The cold water brought it back to life and it began to cry again, whereat Spiltdorph took off his coat and wrapped it tenderly about it. 

Question: "Who washed in the brook?"

Answer: "A dog"
Answer: no

Problem: Washington (CNN) -- The Pacific island nation of Palau has agreed to take in 17 Chinese Muslims held at the U.S. prison camp at Guantanamo Bay, Cuba, the country's ambassador to the United States said Wednesday. The map shows the Pacific island nation of Palau in relation to China. Details of the transfer are still being worked out, Ambassador Hersey Kyota told CNN. But Kyota said his country, a former U.S. Pacific trust territory, has agreed to take in the ethnic Uighur detainees "for humanitarian reasons" and because of the "special relationship" between Palau and the United States. U.S. State Department spokesman Ian Kelly would not comment on the announcement, telling reporters, "We're still involved in ongoing discussions." The agreement includes some U.S. aid for Palau, Kyota said, but he said those details remained to be worked out as well. The country, with a population of about 20,000, is about 1,000 miles southeast of Manila, Philippines, and about 4,600 miles west of Hawaii. Palau has received nearly $900 million in U.S. aid since independence in 1994, according to congressional auditors, and depends on Washington for defense. The "Compact of Free Association" between Palau and the United States is up for review, but Kelly said any additional aid offer "is not linked to any other discussions we may be having with the government of Palau." The Uighurs were accused of receiving weapons and military training in Afghanistan. 

Question: "Which country has a population of about 20,000?"

Answer: "Pacific Islands"
Answer: no

Problem: 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. 

Question: "This famous explorer , after reaching China's capital city reported that the Chinese used what color rocks to make fire?"

Answer: "Marco Polo was amazed they used black rocks for fuel"
Answer:
yes
