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.
