Problem: Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better.

Question: "What does electromagnetic energy create that we see when it travels through space?"

Answer: "Comets"
Answer: no

Problem: Triumph and Disaster: The 20th century saw a stupendous release of energies that had been pent up for the 250 years of Tokugawa isolation. By 1930 raw-material production had tripled the figure of 1900, manufactured goods had increased twelve-fold, and heavy industry was galloping towards maturity. Britain led the World War I Ailies in large orders for munitions, while Japan expanded sales of manufactured goods to Asian and other markets cut off from their usual European suppliers. Merchant shipping doubled in size and increased its income ten-fold as the European fleets were destroyed. Setbacks in the 1930s caused by the European postwar slump were only a spur to redouble efforts by diversifying heavy industry into the machine-making, metallurgical, and chemical sectors. Even the terrible 1923 Tokyo earthquake, which cost over 100,000 lives and billions of dollars, provided another stimulus due to the construction boom that followed. Riding the crest of this economic upsurge were the zaibatsu conglomeratesa dozen family-run combines, each involved in mining, manufacturing, marketing, shipping, and banking. These tightly controlled commercial pyramids were the true heirs to the old feudal structures. Japan's progress toward parliamentary democracy was halted in the 1930s by the growing nationalism being imposed on government by the generals and admirals. They proclaimed Japan's mission to bring progress to its backward Asian neighbors in language not so very different from that of the Europeans in Africa or the US in Latin America. After the Russian Revolution of 1917, the Soviet Union was regarded as a major threat to Japan's security, and the army felt it needed Manchuria and whatever other Chinese territory it could control as a buffer against Russian advances. In 1931 the Japanese occupied Manchuria. And then in 1937, with the popular support of ultra-right-wing groups, the army overrode parliamentary resistance in Tokyo and went to war against the Chinese Nationalists. By 1938, they held Nanking, Hankow, and Canton. Japanese expansionist policies were leading to direct confrontation with the West. Japan hoped that war in Europe would divert the Soviet Union from interference in East Asia, giving Japan a free hand both in China and, through its alliance with Germany, in French IndoChina after the defeat of France. The US responded to the Japanese invasion of IndoChina with a trade and fuel embargo, cutting off 90 percent of Japan's supplies. The result was the attack on the American fleet at Pearl Harbor (7 December 1941) and total war.

Question: "How long after occupying Manchuria did Japan hold Nanking?"

Answer: "7 years"
Answer: yes

Problem: Hotel California My first thought: I was going crazy. Twenty-four hours of silence (vacuum, remember); was I hallucinating noises now? I heard it again. It was a fine bell, reminiscent of ancient stone churches and the towering cathedrals I'd seen in documentaries. And accompanying the bell, I saw a light. Now, there were two things here that made ridiculously small amounts of sense. First, the whole in-a-vacuum why's-there-a-bell thing. Second, I was floating in the dark remnants of my broken ship, and any conceivable light sources were not within view; starlight is a distinctly different color and significantly less bright. These signals were the heralds of my saviors. The first words they said to me meant nothing. I wasn't listening; I didn't care; I was going to live; I was going to keep breathing. Next to those, nothing else mattered. The recycled air tasted sweet in my mouth, and all thoughts that crossed my mind were cheap metaphors about life-giving substances and how breathing was like sex, only better. (I reserved the right to revise this opinion later.) When I was done mentally exclaiming over my impossible rescue, I looked around. The ship, it was odd and old, either so outdated or so heavily modified that I couldn't tell what make it was, and somehow, the crew standing around me fit the same description, a singularly atypical amalgamation of folk. And me, I guess I was one more piece in their puzzle. I was one more scrap to weld onto the rest, one more stranded survivor who was found. I was now one of them.

Question: "Why did the first words the writer's saviours said mean nothing to him?"

Answer: "He wasn't listening"
Answer:
yes
