Politician: My tax reform plan will cut taxes by $600 to $1000 for low-income families, increasing their take-home pay by anywhere from 10 to 15%. Clearly this plan will benefit low-income families.
To weaken above argument, we need to find if there is any catch for low-income families under the new tax plan which will either harm or mitigate the benefit mentioned in the argument.
A. The tax reform plan would cut taxes by an even larger percentage for middle- and high-income families.
Tax plan may be better for middle income but low-income families are still benefitting.
B. Rent in low-income areas has increased by approximately 20% over the last 10 years.
Increase in rent is irrelevant in this case. If tax plan is doing some good, above argument still hold.
C. The tax reform plan will eliminate a food subsidy program that granted low-income families $100 per month in food vouchers.
Correct answer - Tax plan is taking away something from low-income families.
It is given that they will lose around $100/month ( $1200/year). As per original argument families will save $6000-$1000/year ( taxes saving are mostly mentioned annual basis) so overall no benefit to low-income families.
D. Recent polls show that, while the tax reform plan has the support of over 60% of high-income families, it is supported by less than one-third of low-income families.
no information about drawback for low-income families, support from any group not so useful.
E. Economists are unsure what effect the tax reform plan will have on the unemployment rate.
no information about unemployment and low-income families available.
