Final answer:
All the aspects listed are typically observed in upper-middle-income countries; thus, option E) None of the above is the correct answer.
Step-by-step explanation:
Among the upper-middle-income countries, also known as industrializing or developing countries, the following aspects are observed except which one? To answer this, we need to assess the individual choices presented. The World Bank classifications update yearly and define upper-middle-income countries as those with a Gross National Income (GNI) per capita between $4,036 and $12,475. Hence, option A) is accurate. As economies transition from agricultural to industrial bases, the percentage of the population in agriculture declines and more people move into the industrial sector, confirming options B) and C). Additionally, with this transition, urbanization typically increases, supporting option D). Therefore, the correct answer is E) None of the above, as all these aspects are generally observed in upper-middle-income countries.
