    The question is testing whether the candidate understands that a vector is a set of numbers (2 in GCSE but often 3 at A-level) that describe a displacement rather than a position.

    A common error is for candidates to think that a position (3,2) say is the same as a vector 3 and 2 in a vertical bracket. It just happens that the position (3,2) has a position Vector from the origin that has the same numbers in it.
