Which of the following best describes assembly-line production? a. a process using interchangeable parts that constructed products entirely instead of by individual piece b. a process using workers to construct products more efficiently by dividing labor into specialized tasks c. two or more lines of workers that simultaneously constructed products in order to reduce labor time d. a line of workers who provided quality assurance by inspecting every product assembled on the line

The correct answer is B. The assembly-line production is a process using workers to construct products more efficiently by dividing labor into specialized tasks.

An assembly line is generally constituted by a belt, called a conveyor belt, which slides carrying the different objects to be assembled to obtain the finished product; each worker can thus assemble a single piece, through repetitive and mechanical movements, allowing a considerable saving in production times: since this method went into operation, in the Ford factory, the time needed to produce a single car was reduced by 12 hours to just 1 hour.

the correct answer is a) egypt and china.

egypt and china are two of the world’s oldest civilizations known by man. both ancient empires have left a great historic and cultural legacy to the world through archeology. both civilzations developed complex social relations, had deep religious beliefs, had dominion of agriculture and left writing records to understand their customs and culture.

among the requirements to consider a civilization, we find urbanization, writing records, a place of residence, agriculture methods, technological specialization, means of transportation, currency, population density, social stratification, and political integration.
