Consider the following information: Region | Name of the mountain range | Type of mountain 1. Central Asia | Vosges | Fold mountain 2. Europe | Alps | Block mountain 3. North America | Appalachians | Fold mountain 4. South America | Andes | Fold mountain In how many of the above rows is the given information correctly matched?

Rows 3 and 4 are correctly matched: the Appalachians in North America are old fold mountains, and the Andes in South America are young fold mountains. Row 1 is incorrect because the Vosges are located in Europe (France), not Central Asia, and they are block mountains (formed by faulting), not fold mountains. Row 2 is incorrect because the Alps in Europe are fold mountains (formed by the collision of the African and Eurasian plates), not block mountains. Hence two rows are correctly matched.
