Which of the following is/are example(s) of the assertion that cultural differences existing in the world is the outcome of human interaction with the environment? (A) People of Amazon basin live in houses with a steeply slanting roof. (B) People of Amazon practice 'slash and burn agriculture'. (C) People in Bihar and Assam make handicrafts from silk.

The correct answer is: All (A), (B), and (C) Important Points All of the given examples demonstrate how cultural differences can be attributed to human interaction with the environment: (A) People of the Amazon basin live in houses with a steeply slanting roof. This architectural style is influenced by the heavy rainfall in the region. The steeply slanting roofs help to quickly shed water and prevent it from accumulating on the roof. (B) People of the Amazon practice 'slash and burn agriculture'. This farming method involves cutting down and burning vegetation to clear land for cultivation. It is adapted to the environment of the Amazon rainforest, where the soil is nutrient-poor. The ashes from the burning provide temporary fertility for crops. (C) People in Bihar and Assam make handicrafts from silk. The availability of silk-producing insects such as silkworms in these regions has led to the development of silk-based handicrafts. The local environment provides the necessary resources for silk production and encourages the development of related cultural practices. Therefore, all of the given examples illustrate how cultural differences are influenced by human interactions with the environment.
