I want to know the answer to the following question:
What was most of Nigeria's federal income being spent on?
All the background I'm provided with is that "Babangida's tenure was marked by a flurry of political activity: he instituted the International Monetary Fund's Structural Adjustment Program (SAP) to aid in the repayment of the country's crushing international debt, which most federal revenue was dedicated to servicing.". Is that enough to answer the question?
Answer: yes
