Final answer:
The sentence 'On the carpet walked she' is syntactically correct but semantically incorrect.
Step-by-step explanation:
The sentence 'On the carpet walked she' is syntactically correct but semantically incorrect. This sentence follows the structure of an inverted sentence, where the subject ('she') comes after the verb ('walked'). In English, this structure is uncommon and would create confusion for readers or listeners because it goes against the standard word order. The correct and more commonly used sentence would be 'She walked on the carpet.'
