My younger sister is reviewing for an upcoming exam using quia, which her teacher suggested.
She ran across the following question:
Help me carry _______ boxes into the house.
The options are 'those' and 'them.' The service indicates that the correct answer is 'them,' which is utterly baffling to me. I am not particularly great with grammar, but I don't think this can be right -- it is nearly painful to my ears.
What is the correct answer? If it is 'them,' then what is the explanation.
