Answer:
b. 15 seconds
Explanation:
While driving her children, Adriana's car broke down. She called her husband on the cell phone for the number of a towing company. If the children's behavior prevents her from repeating the number to herself, most likely Adriana will need to dial the phone number within the next 15 seconds or she will forget the number.
The phone number is committed to her short-term memory and the short-term memory can store an average of 7 bits of information within a duration of 15-30 seconds, if Adriana does not consolidate the information by repeating the number till it is transferred to the long-term memory, she is most likely to forget the number within 15 seconds.
