A steep yield-curve occurs when long-term interest rates are much higher than short-term interest rates.

A steep yield-curve indicates that investors anticipate rapid economic growth.

When the economy is healthy, the yield on long-term bonds is often slightly higher than on short-term bills.

None of these.
