Question

which countries are within the tropical climate zone? select two answers.

Explanation:

1. Tropical climate zone (Köppen climate classification) is between the Tropic of Cancer and Tropic of Capricorn. Brazil (Amazon rainforest, equatorial/tropical) and Nigeria (West Africa, tropical savanna/rainforest) lie in this zone.
2. Countries like Russia, Canada, USA (most parts) are in temperate/polar zones, not tropical. Philippines and parts of India/Indonesia also, but from the map's labeled countries, Brazil and Nigeria are clear tropical zone countries.

Answer:

Brazil, Nigeria (assuming these are among the options; from the map, Brazil (in South America, tropical region) and Nigeria (in West Africa, tropical region) are typical tropical climate zone countries. If the options include these, they are the two. For example, if options are like: A. Brazil, B. Russia, C. Nigeria, D. Canada, then A and C.)
