The correct answer to this open question is the following.
Chunking involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of short-term memory.
Chunking allows you to take information and put it in small categories or groups for better understanding. This way you allow your memory to better understanding a piece of information. Is like when you try to remember a phone number. Instead of memorizing the whole number, you dive it by parts. So if you repeat that information through rehearsal, you will be able to remember most things needed on a daily basis.
