Economist: Sales taxes do not provide a fair alternative to income taxes. Low-income households must spend nearly all of their disposable income on consumption items they need to live, while high-income households can afford to buy those items and then put a substantial amount of their earnings into savings. Hence a sales tax
Which of the following most logically completes the argument?"Hence" has a meaning similar to "therefore." So, the last sentence of the passage must state a conclusion that follows from the statements that precede it.
A. could result in households with different incomes paying different amounts of taxesThis choice states the opposite of what logically follows from the passage. After all, the passage says that low-income households spend on "consumption items" and that high-income households "buy those items," meaning the same items.
If people buy the same items, they will pay similar amounts of sales taxes. So, the information in the passage indicates that a sales tax could result in households with different incomes paying similar amounts of taxes.
A statement that is the opposite of what follows from the passage cannot be a conclusion that follows from the passage.
Eliminate.
B. could tax a smaller percentage of the earnings of high-income households than of low-income householdsThe passage says the following:
Low-income households must spend nearly all of their disposable income on consumption items they need to live, while high-income households can afford to buy those items and then put a substantial amount of their earnings into savings.Notice that that information indicates that low-income households and high-income households buy the same items and thus pay similar amounts of sales taxes.
At the same time, by definition, high-income households have more earnings than low-income households. So, the same amount of sales taxes will be a smaller percentage of the earnings of high-income households than it is of the earnings of low income households.
Thus, this choice follows directly from what the passages says.
Keep.
C. would put a disproportionately high burden on the purchasers of the most expensive consumption itemsThe passage says nothing about "the purchasers of the most expensive consumption items." So, this choice already doesn't seem to follow from the passage.
Meanwhile, what the passage says indicates that sales taxes put a disproportionately high burden on low-income households, which presumably are not purchasers of the most expensive consumption items. So, this choice says basically the opposite of what the passage says.
Eliminate.
D. should be applied only to the wealthiest householdsThe passage indicates that, since high income households and low income households pay sales tax on the same "consumption items," "sales taxes do not provide a fair alternative to income taxes."
That information does not support taking any specific course of action, such as applying sales taxes to only the wealthiest households. It's just information indicating that the outcome of using sales taxes is not fair
Eliminate.
E. should not be used to tax any consumption itemsThe passage indicates that, since high income households and low income households pay sales tax on the same "consumption items," "sales taxes do not provide a fair alternative to income taxes."
Notice that "do not provide a fair alternative to income taxes" is not the same as "should not be used to tax any consumption items." After all, there could be situations in which sales taxes are applied to certain consumption items without being an "alternative to income taxes." For instance, a sale tax could be used to tax only fuel use for the purpose of paying for road maintenance.
So, this choice does not follow from the passage.
Eliminate.
The correct answer is (B).
