Most of Grameen Bank's borrowers use the small loans to start businesses by, for instance, buying a cow to produce milk, or a rickshaw, or materials to make cloth or pottery.
 Grameen Bank is a financial establishment.
It provides people with money and it's literally a bank, therefore by definition it has to be a financial establishment. It's difficult because the system is probably not familiar with these terms and doesn't really understand what is being said.
