Not necessarily so. You are absolutely right that a 'wind vector' states direction from (and strength) but that's not what the question is giving. Rather it states 'geostrophic wind direction of 020T' so it is not a 'wind vector'. Whether the way the question is worded is deliberate, or accidental, is moot but often questions are worded like this in order to test the candidate is thinking about what is happening rather than lamely following a rule without, necessarily, understanding the application. I stand by my earlier post.
