Someone from our company will meet you at the airport.
Can I paraphrase it as:
You will be picked up by someone from our company at the airport.
The key gives only one correct answer:
You will be met by someone from our company at the airport.
I'd say no. Because what you've done hasn't actually paraphrased, it's changed the meaning of the sentence. The original sentence may have an ambiguous outcome. However, your sentence states what will happen. The correct answer recognises that, maintaining the ambiguity.
