Concept:Children's cognitive development and language are strongly shaped by the environment around them, especially culture and community.
Explanation:First, cognitive growth and language learning happen together in social contexts. Culture provides the words, grammar, and communication styles that children absorb. Community offers daily interactions and experiences that build thinking skills. For example, a multilingual environment boosts mental flexibility. Social norms and literacy resources also influence how language develops.
Option A is wrong because research shows a deep link between cognition and language. Option C (stimulus‑response and imitation) covers only a small part of the process and misses the broader social influence. Option D (innate language tool) ignores the crucial role of cultural and community factors in shaping language.
Answer:Therefore, the correct choice is B: children's cognitive development and language are closely related to the culture and the community in which children live.
