Final answer:
The statement that children cannot make negative statements by inverting word order is false, as children have an innate ability to learn language structure, evidenced by Noam Chomsky's Language Acquisition Device hypothesis. The word closest in meaning to 'hypothesis' is 'suggestion.'
Step-by-step explanation:
The statement that children never make negative statements by reversing an order of words in a sentence related to the innateness hypothesis is false. Children do have the innate biological capacity for language acquisition, often hypothesized as the Language Acquisition Device (LAD) as proposed by Noam Chomsky. While they may make errors, these are more representative of learning rules and exceptions in a language rather than a lack of innate ability.
The closest meaning to hypothesis among the given options is suggestion. A hypothesis is not a confirmed fact or law but rather a suggested explanation that can be tested through research and experimentation.
Moreover, as children's cognitive development progresses, including their theory-of-mind (TOM), they begin to understand that others have thoughts and feelings that are different from their own, which further contradicts the notion that they can't make complex language constructions like negative statements.
