Although he speaks of the Far East between the 15th and 18th centuries as a single world-economy, he says it in fact comprised three "gigantic world-economies: Islam, overlooking the Indian Ocean from the Red Sea and the Persian Gulf, and controlling the deserts stretching across Asia from Arabia to China; India, whose influence extended throughout the India Ocean, both east and west of Cape Comorin; and China, at once a great territorial power- striking deep into the heart of Asia-and a maritime force, controlling the seas and countries bordering the Pacific."

The effect from transverse webs and frames and the effect from collision velocity on ship bow collision properties are also studied in this paper. 7. The idea of buffer bow is put forward from aspects of the overall situation of environmental protection and reducing the damage of struck shipside caused by striking bow. The influence of curvature of bow shape on mode of distortion, collision force, collision force density and energy absorption of bulbous bow is described detailedly through a series of collision numerical simulation for bulbous bows that have different curvature.

But the power of waves striking the shore can still be very great. During a winter gale, waves sometimes strike the shore with the force of 6,000 pounds for each square foot. That means a wave, 25 feet high and 500 feet along its face, may strike the shore with a force of 75 million pounds.Yet the waves, no matter how big or how violent, affect only the surface of the sea. During most raging storms, the water a hundred fathoms(600 feet) beneath the surface is just as calm as on a day without a breath of wind.Question: From your reading of the paragraph, which of the following is true?
