Answer: C - The lasting effect of some major events such as the 9/11 terrorist attacks is due to flashbulb memories.
Key Takeaway: Flashbulb memories stay vivid in one’s long term memory structure because of their impact and their gravity. The sight of the planes crashing into the twin towers is more likely to be retained more vividly than simple date, for example. Both the gravity and the impact of the crashes means that the memory will be kept alive longer.
