Text: In simple terms, increasing payroll taxes by 1.86 percent (a 15percent increase over the 2001 rate paid by employers and workers) now could head off a Social Security shortfall for 75 years.
Entailment: A 1.86 percent increase to payroll taxes could prevent Social Security from running a deficit for the next 75 years.
Contradiction: A 1.86 percent increase to payroll taxes wouldn't be enough to prevent a shortfall in Social Security funds.
