Final answer:
MDCs have a higher percentage of tertiary activities compared to LDCs.
Step-by-step explanation:
MDCs, or More Developed Countries, typically have a higher percentage of tertiary activities compared to LDCs, or Less Developed Countries. Tertiary activities refer to services such as education, healthcare, finance, and tourism. MDCs have a more developed infrastructure and higher levels of industrialization, which leads to a greater emphasis on these service-based activities. For example, in MDCs, there are more schools, hospitals, and financial institutions compared to LDCs.
