The terms are mixed up with the definitions. They are:
Annual percentage yield, Interest thresholds, Variable interest rates and Money market account.

The annual percentage yield is the interest rate that shows how much your account will increased by in a year.
2. Different interest rates paid for different size balances, with higher balances earning higher rates ⇒ Variable interest rates.
Variable rates are meant to reward higher balances are so are different per account balances.
3. The minimum balances before the bank begins paying interest ⇒ Interest thresholds.
Banks have interest thresholds which show the minimum value that an account must have in order to start accruing interest.
4. A savings account that offers a higher rate of interest when you make large deposits ⇒ Money market account
Money market accounts make returns by trading short term instruments which enables them to offer higher rates of return. They however require large deposits.
