Read the following paragraph and choose the correct statement.

Laura Strong is one of atleast 3.8 million Americans in 2014 who've qualified for federal programs that tie payments to income and eventually forgive debt for some struggling borrowers, leaving taxpayers to pick up the tab President Obama has praised the programs for offering a lifeline to borrowers who'd otherwise default scarring their credit. Strong pays about $100 a month on her federal loans.

Income-based repayment was introduced under President Clinton, but the programs weren't heavily promoted until late 2013, when the Obama administration began sending e-mails to borrowers, including

Strong, telling them, ‘Your initial payment could be as low as $0 a month.’ The number of people using these plans has quadrupled since 2012.
