To determine which statement is true based on the context of population density, let's analyze each option:
A. The least densely populated countries are in southern Europe.
- This statement would need verification against specific data on population density in southern Europe. It's not universally true without data.
B. The most densely populated countries are in central Europe.
- Similar to A, this requires specific data; however, some central European countries do have higher population densities.
C. More than half of all Europeans live in countries shaded blue.
- This is a quantifiable statement and its accuracy depends on the specific populations of the countries represented. If data from the map indicates that a significant portion of the total European population is in blue-shaded countries, this may be true.
D. Countries of the same color have the exact same populations.
- This statement is typically false, as population densities can vary widely within color categories if the colors represent ranges or categories and not exact figures.
Without the actual map and data, I can't definitively say which statement is true; however, in a normal situation, option C might be a strong contender if blue represents densely populated areas where a large portion of the population resides. Please check the map for numerical and factual confirmation on these statements.
