For most people the sea was remote, and with the exception of early intercontinental travelers 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 of the route to estimate the length of cable that had to be manufactured.
22. It was ________ that asked Maury for help in oceanographic studies.
A) the American Navy
B) some early intercontinental travellers
C) those who earned a living from the sea
D) the company which proposed to lay an undersea cable
