| The creation of a universal language
uniting all mankind is an idea that has interested scholars for several
centuries. It is an exciting idea! Imagine a language which can break down the
barriers that tend to separate the different peoples of the world. The idea has
not been left to gather dust. Various attempts have been made to invent such a
language. The most widely known invented language, Esperanto, has about one
million speakers, but very few speakers use it as their everyday language.
Considering that the world population is already over four billion, this is not
a truly popular universal language. In fact, no invented language has ever been
widely accepted. The suggestion has been made that a true universal language exists already. Margaret Mead, among others, recently proposed that sign A. artificial language B. natural language C. universal language D. sign language [单选题]生产经营单位依照规定委托工程技术人员提供安全生产管理服务的，保证安全生产的责任由( )负责。
