4.During the nineteenth century， Britain's urban popu-lation increased as its rural population diminished. A historian theorizes that， rather than industrialization's being the cause， this change resulted from a series of migrations to urban areas， each occasioned by a depression in the agrarian economy. To test this hypoth-esis， the historian will compare economic data with population census data. The historian's hypothesis would be most strongly supported if which of the following were found to be true？
（A） The periods of greatest growth in the industrial economy were associated with a relatively rapid decline in the rural population.
（B） The periods of greatest weakness in the agrarian economy were associated with relatively slow growth in the population as a whole.
（C） Periods when the agrarian economy was compar-atively strong and the industrial economy com-paratively weak were associated with a particu-larly rapid decline in the rural population.
（D） Periods when the agrarian and industrial econo-mies were both strong were associated with particularly rapid growth in the urban popula-tion.
（E） The periods of greatest strength in the agrarian economy were associated with relatively slow growth in the urban population.

答案是E，为什么呢？我感觉A才是对的。
