I agree with Rusty.
As a side note, I think that, although is actually poorly written, the idea is to encourage you to say what you would have done if you were a "deportista" or a "dependienta" to answer.
If the author had said "cómo completaron", she would be asking you to perform an impossible task, which is to accurately divine how they responded. Instead, she's asking you to make some sort of exercise on empathy or affinity with those people.
