Answer: 1- Short term Memory 2-Rehearsing.
Explanation: Short-term memory is the cognitive ability that allows individuals to hold information as available for a while.
A common example of short-term memory is for instance when someone tells us a phone number and we remember it for a short period until we save it on our phone.
After a while, we forget the number because it was information held in short-term memory.
To maintain this information in the short term memories one has to use certain techniques.
Those techniques imply rehearsing said information to maintain that information for a longer period.
In this particular case, the information was lost from the short-term memory because the phone conversation distracted from rehearsing the information.
