Jen's Dad Sends Her to the Grocery Store for a Few

Jen's dad sends her to the grocery store for a few last-minute dinner items. Jen repeats the list of ten items as she walks to the store but can remember only the first and last three items when she gets there-she is unable to remember the four in the middle. Why did she forget the four items in the middle of the list?

A) The items were probably vegetables, since research shows that vegetable names are difficult for most people to remember.
B) Exercise tends to degrade information if it has just been learned.
C) Because her father gave her the list all at once, Jen wasn't able to hold each item in her short-term memory long enough to encode it for long-term storage.
D) The four middle items never entered her sensory memory.
