题目解析:
定位到首句: With the advent of projection, the viewer's relationship with the image was no longer private, as it had been with earlier peepshow devices such as the Kinetoscope and the Mutoscope, which was a similar machine that reproduced motion by means of successive images on individual photographic cards instead of on strips of celluloid.表达出来的意思是:Mutoscope是与Kinetoscope相似的机器,它通过独立胶片上的连续影像来复制动态画面,而不使用胶片,可知Mutoscope与Kinetoscope的不同在于制造影像的材料不同。因此选择D。注意:B选项中”more than one person could view the images at the same time(许多人可以同时观看一部电影)” 是由the advent of projection(放映机的发明)实现的,而不是Mutoscope。
