16. B. can't be correct. Think of the huge, hot, humid rainforest. Please check your text again.

19. B. limits the majority of the population to a very small area. Go with your second choice.

21. I don't know about this one. It depends upon how the "heart of Mexican culture" is defined.

To check if your answers are correct, let's go through each question and explanation behind the answer choices.

16. Although most of South America lies within the tropical latitudes, the answer is (a) climate and vegetation differ greatly in the region. To understand why, you can eliminate choices (b), (c), and (d) by considering the information provided. None of the answer choices mention cold ocean currents, lack of tropical vegetation, or growing seasons being influenced by highlands and mountains, so those can be ruled out. By process of elimination, you are left with choice (a), which states that climate and vegetation differ greatly in the region, which aligns with the fact that most of South America lies within tropical latitudes.

19. The answer for this question is (c) in the country's major cities located in the central plateau. To determine the correct answer, you need to consider the geographic information about Mexico provided in the question. Choices (a) and (d) do not align with the information, as they mention different geographic regions compared to the options provided in the question. Choice (b) mentions the Pacific coast, which is not the location where most of Mexico's people live. Choice (c) refers to the major cities located in the central plateau. This option aligns with the information presented in the question and is the correct answer.

21. The answer for this question is (a) urban areas. The question asks about the heart of Mexican culture today, and choices (b), (c), and (d) do not directly mention the urban areas. Choice (d) specifically mentions mountainous regions, which are not specified as the heart of Mexican culture. Choice (a) refers to urban areas, which are typically the centers of culture and diverse activities. Therefore, the correct answer is (a) urban areas.

Based on the explanations provided, your answers for these questions are correct:
16. B
19. C
21. A
