Teachers, save “Inventions from the 1950s” to assign it to your class.

Put the inventions in order of importance and explain why you think they are the most important. No wrong answer - what are your ideas? And which is the least important, and why? 把发明按重要性顺序排列，并解释为什么你认为它们是最重要的。没有错误的答案 - 你有什么想法？哪个最不重要，为什么？
