Which barrier to economic development is shown in the following examples? I. the high rate of HIV infection in underdeveloped nations II. the use of children as soldiers in Uganda’s army in the early 2000s III. low literacy rates in underdeveloped nations with limited exposure to adequate education

These examples point to inadequate social conditions that hinder people’s health, safety, and education. The use of child soldiers and limited access to education are especially clear signs of low social welfare. HIV is a widespread disease, but that describes only the first example, not all three. The best answer is low levels of social welfare.
