    Weight is assigned value of 2, instead of using a 2. informat. try it.

    james is correct

    @3, I think your explanation is wrong, weight 2 means column input, so input value of 2, you can try weight 1, then you will find the value of weight is 7.

    D is the correct answer try it

    wrong explanation James, the 2 is read from the second column of the raw data file. Please check.
