Foundation: 5% spending goal but no minimum spending requirement

2015 exam question 2

What does this mean? Does it mean even though the foundation has a 5% spending goal but it doesn’t have to meet this objective?

I see 5% as the average risk ability: anything below increases (and above decreases) risk ability
