  1. Only one
  2. Only two
  3. Only three
  4. All four

Answer

Correct Answer

Only two

Explanation

The Appalachians in North America and the Andes in South America are fold mountain systems, so rows 3 and 4 are correct. The Vosges are located in Europe and are associated with block faulting, not Central Asia or fold-mountain formation. The Alps are young fold mountains, not block mountains. Therefore, only two rows are correctly matched.
