Which detail from the story "the gift of the magi" best supports the inference that jim and della are barely making it by financially? "now, when the income was shrunk to $20, though, they were thinking seriously of contracting to a modest and unassuming d." "tomorrow would be christmas day, and she had only $1.87 with which to buy jim a present." "a furnished flat at $8 per week. it did not exactly beggar description, but it certainly had that word on the lookout for the mendicancy squad." "twenty dollars a week doesn’t go far. expenses had been greater than she had calculated. they always are."
