The following text discusses child development.
Children learn language at an astonishing rate during their first years of life, acquiring thousands of words and complex grammatical rules without formal instruction. Linguists call this period the "critical window" for language acquisition. Children raised in multilingual households typically become fluent in all their languages without confusion, suggesting the young brain has remarkable capacity for processing multiple linguistic systems simultaneously.
According to the text, what does multilingual child development demonstrate?
Children should only learn one language at a time
The young brain can effectively handle multiple languages at once
Formal instruction is required for language learning
Languages learned in childhood are quickly forgotten
Correct Answer: B
Choice B is the correct answer. The text states multilingual children "become fluent in all their languages without confusion," showing "remarkable capacity for processing multiple linguistic systems simultaneously."
- Evidence: Multilingual children without confusion.
- Reasoning: Success demonstrates brain capacity for simultaneous languages.
- Conclusion: Young brains can handle multiple languages effectively.
Choice A is incorrect because the text describes successful multilingualism. Choice C is incorrect because the text says children learn "without formal instruction." Choice D is incorrect because the text doesn't mention forgetting.
