1. Educational television is a contradiction in terms. While a classroom encourages social interaction, television encourages solitude. School is centered on the development of language, but television depends upon constantly changing visual images. And in a classroom, fun is merely a means to an end, but on television it is the end in itself.
Upon which one of the following assumptions does the author rely in the passage?
(A) The classroom should not be a place where anyone has fun.
(B) Only experiences that closely resemble what takes place in the school environment can be educational.
(C) Television programs reinforce some of the values of the school environment.
(D) Educational television programs are qualitatively better than most other television programs.
(E) The potential of television as a powerful learning tool has not yet been realized.

答案B, 我觉得E也能作为假设，为何E不对？
in a classroom, fun is merely a means to an end, but on television it is the end in itself. 这句话该如何理解？请大家指教。

文中主要讲了电视教育作为一种教育的方式和课堂相比的问题。E是说电视作为可以用来进行教育的一种工具没有发挥其潜能，主体被换掉了，另外，E也只是一个结果，不是前提。
中文意思：教室中，乐趣是达到目的的一个手段，而在电视教育中，乐趣成了终极目的。
