Nigeria’ s bench mark interest rate used to be 11%.
A、T
B、F
【正确答案】：A
【题目解析】：听力原文：Nigeria’s central bank raised its bench mark interest rate by 1 percentage point, to 12%.
Nigeria's currency, the naira, has been hurt by the fall in oil prices. That has helped push
up inflation to 11. 4%.本题考查应对数字。原文说尼日利亚央行将基准利率上调1个百分点，至12%。题干说尼日利亚的基准利率曾经是11%。根据原文上调1个百分点，至12%可知原来是11%。与原文说法相符，所以正确。
