  average household budget must have increased by

  30 percent over the last five years.

  the argument relies?

  (A)The average number of factory-new cars pur-

  chased per household has remained unchanged

  over the last five years.

  buying factory-new cars has risen 30 percent in

  the last five years.

  (C)The proportion of the average household budget

  spent on all car-related expenses has remained

  unchanged over the last five years.

  (D)The proportion of the average household budget

  spent on food and housing has remained

  unchanged over the last five years.

  new cars has increased by 30 percent over the
