这是一个判断题,判断对,错,未提及(T/F/NG/)
文章是:The telegraph,a divice first proposed in 1753 and firs built in 1744,was an impractical machine up until that point,requiring 26 separate wires,one for each letter of the alphabet.Around that time two Gream engineers had invented a five-wire model,but MORSE wanted to be the first to reduce the number of wires to one
Too many separated wires of the telegraph prototype made it unfeasible.判断这是正确 ,错误,还是未提及.
在我看来,这是正确的,本题考的是对unfeasible和impractical的理解,前者是“不能实行的,难实施的”,在这里理解成后者的“不切实际的,无用的”,文章末尾提到对码的改进过程,从26到5,再到摩斯想浓缩为1,可以看出字母变少是势之所趋,26个字母太过繁琐,实用性不强
