问题如下：
8. Based upon Statement 4, the higher rate of per capita income growth in Country A is least likely explained by the:
选项：
A.rate of investment.
B.growth of its population.
C.application of information technology.
解释：
B is correct.
Population growth can increase the growth rate of the overall economy, but does not impact the rate of increase in per capita GDP. Therefore, population growth does not explain Country A’s higher rate of per capita income growth. An increase in labor force participation could, however, raise the growth of per capita GDP.
考点：哪些因素可以促进人均GDP快速增长。
解析 ：
B选项，人口的增长可以使得一国总的GDP快速增长，但是不会影响人均GDP，所以它应该入选。
人均产出的影响因素和技术水平的进步，以及人均资本占有量有关。C选项，先进的技术水平能带动人均GDP的增长，本题不入选。
A选项，较高的投资能带来较高的人均资本占有量，资本深化的作用也会带来经济的增长。本题不入选。
这题答案错了 应该是a吧 看解析
