38) The politicians cannot be telling the truth about a reduction in taxes. This year my taxes must have been higher than ever, because I was able to save less money than last year or the year before.

All of the following point to an error in reasoning in this passage EXCEPT

1. taxes are not the year's only expense.
2. this year's earnings may have been smaller than last year's.
3. politicians are frequently guilty of exaggeration or equivocation.
4. this year's tax deductions may have been smaller than last year's
5. income from invested income may have declined this year due to lower interest rates.
