60. We’ll have to use the restrooms on the next floor because the ones on this floor are not in working condition.A. out of work B. run out of C. torn down D. out of orderVII. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.Recent technological advances in manned and unmanned vehicles, along with breakthroughs in satellite technologyand computer equipment, have overcome some of the limitations of divers and diving equipment for scientists doingresearch on the great oceans of the world. Without a vehicle, divers often became sluggish, and their mentalconcentration was severely limited. Because undersea pressure affects their speech organs, communication among divershas always been difficult or impossible. But today, most oceanographers avoid the use of vulnerable human divers,preferring to reduce the risk to human life and make direct obervations by means of instruments that are lowered intothe ocean, from samples take from the water, or from photographs made by orbiting satellites. Direct observations of theocean floor can be made not only by divers but also by deep-diving submarines in the water and even by the technologyof sophisticated aerial photgraphy from vantage points above the surface of more than seven miles and cruise at depthsof fifteen thousand feet. In addition, radio-equipped buoys can be operated by remote control in order to transmit databack to land-based laboratories via satellite. Particularly important for ocean study are data about water temperature,currents, and weather. Satellite photographs can show the distribution of sea ice, oil slicks, and cloud formations overthe ocean. Maps created from satellite pictures can represent the temperature and the color of the ocean’s surface,enabling researchers to study the ocean currents from laboratories on dry land. Furthermore, computers helpoceanographers to collect, organize, and analyze information from submarines and satellites. By creating a model of theocean’s movement and characteristics, scientists can predict the patterns and possible effects of the ocean on theenviroment.Recently, many oceanographers have been relying more on satellites and computers than on research ships or evensubmarine vehicles because they can supply a greater range of information more quickly and more effectively. Some ofhumankind’s most serious problems, especially those concerning energy and food, may be solved with the help of observationsmade possible by this new technology.
