Before the nineteenth century, scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work. For most people the sea was remote, and with the exception of early intercontinental travellers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question "What is at the bottom of the oceans " had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile (起伏形状) of the route to estimate the length of cable that had to be manufactured.

{{B}}TEXT E{{/B}} As the hot arctic summer drew to a close, till the magenta sun only slid along the horizon to sink again at once, the polar bear knew that a hard time lay ahead for her. During the months of night, fifty degrees below zero, her cubs would be born, the great task of motherhood was already begun, the time soon coming when she would bury herself deep down under the snow to give birth.

She must finish fattening herself up for the ordeal, and there was not much time left. She was not clearly aware of what was happening in her body, but the instinct was there to love the unborn cubs, to prepare for them and protect them; she did not risk her body in careless adventures as she would at other times.< A. sliding over the ice sheet B. tiptoeing on the ice sheet C. swimming under the ice sheet D. crawling from behind the seal [多选题]同一层支架上电缆排列配置方式，符合规定的有（）。
