Answer:
B. Did not reduce unemployment as much as desired.
Step-by-step explanation:
After the Financial Crisis hit, the Federal Reserve did three rounds of Quantitative Easing. Quantitative Easing simply consists in injecting large amounts of money in the economy with the goal of boosting activity.
Quantitative easing helped end the recession, but unemployment continued to be high until the second term of Barack Obama, when the three rounds of Quantitative easing had already taken place.
