IV. Ecuador: Yes, the Andes run through the center of Ecuador, dividing the country into distinct geographical regions.

VI. Venezuela: Yes, the Andes extend into western Venezuela, though they are less prominent than in other Andean countries.

SUPSC Prelims Strategy and Tips

For mountain range questions, visualize the geographical extent of major mountain systems. The Andes run along the western coast of South America, so countries in the interior or east would not be affected.
