The best candidates are the countries with the lowest adult literacy rates on the map, which is the group Ethiopia, Somalia, and South Sudan (often given as answer choice E in this AP Human Geography-style question).

Why that group is chosen

  • The map in this common classroom question shows adult literacy rates by country, with darker shading or specific colors indicating lower literacy.
  • Ethiopia, Somalia, and South Sudan all fall into the lowest literacy categories on that map, meaning a larger share of adults cannot read or write proficiently.
  • An international elementary education program aims to address foundational schooling gaps, so countries where many adults missed basic schooling (and thus have low literacy) are typically prioritized for funding.

Why the other options are not as strong

  • Groups like Brazil–Bolivia–Peru or Mexico–Colombia–Ecuador have higher overall literacy compared with Ethiopia, Somalia, and South Sudan, even though there are still regional inequalities.
  • Middle Eastern and Southeast Asian options in the question (for example, Egypt–Libya–Saudi Arabia or Indonesia–Malaysia–Thailand) generally show moderate-to-high literacy on the referenced map, so they are not the top-need cases in this specific comparison.

Key idea to remember

When a map shows adult literacy rates and the question asks where to fund an elementary education program, choose the group of countries shaded to indicate the lowest literacy , because that signals the greatest need for basic education investment.
