Which age group is expected to answer questions related to 'who', 'what', 'where', and 'why'?

Children in the age group of 3-4 years typically start to show significant language development and cognitive skills, which include the ability to answer questions that begin with 'who,' 'what,' 'where,' and 'why.' This period is marked by an increase in vocabulary and an understanding of complex concepts, allowing them to engage more effectively in conversations and express curiosity about their environment.

By this age, children begin to use language to connect ideas and inquire about things, showcasing their growing cognitive abilities. They might start asking questions to gather more information, and their ability to respond to similar questions reflects their comprehension of language and the world around them. This developmental milestone is critical for effective communication and social interaction.

In contrast, younger age groups, such as children aged 1-2 years or 4-6 months, are typically limited in their language skills and understanding. Children in the 2-3 year age range may begin to ask simple questions but are still developing their ability to understand and respond to complex language. Therefore, it is primarily the 3-4 year age group that shows the readiness to engage with 'who,' 'what,' 'where,' and 'why' questions confidently.
