What is the tour for today mainly about? [br]
Many of the innovations in fire fighting that we will be seeing today were developed right here in America. As you can see from these photos, one of the earliest steam powered fire engines, the Joe Ross, was built in 1850 and operated right here in Cincinnati. Driven by four large horses, the ten-ton machine was steered by a single front wheel that was attached directly to the horse team. The steam motor on the Joe Ross was used to power the water pump that the big machine used to fight fires. Over here, we have an actual truck which was built in 1900 by the Waterous Fire Engine Works of Minneapolis. This was the very first fire engine to utilize a single steam motor for pulling the engine as well as pumping the water. As you may notice at the top of the truck, there is a circular platform that holds one end of a long ladder; the revolving platform operates almost like a record turntable in order to make it easier for ladder-operators to access buildings from difficult angles. The idea of the ladder turntable is credited to a San Francisco fireman by the name of Daniel Hayes. Hayes’ lifesaving invention, when combined with the relatively quick response time of the single engine, helped to bring fire fighting into the modern era.
选项
A、A single-engine fire truck.
B、A water-powered fire truck.
C、A record player.
D、A circular ladder holder.
答案
D
解析
细节题。文章后面讲到在一辆(消防)卡车顶端有一个圆形的旋转平台,平台上立着一架云梯,这个发明源自Daniel Hayes。故D项正确。
