Final answer:
The statement is false because the retrieval of inert memories is not guaranteed by simply encountering any retrieval cue, as interference and other memory errors can prevent recall.
Step-by-step explanation:
The statement that inert memories are rarely a problem because the information becomes spontaneously available in the presence of any retrieval cue is false. Memories can indeed be elusive and often require specific cues for retrieval. There are various reasons why retrieval may fail, such as the effects of interference, when newer information hinders the recall of older information (retroactive interference), or when older information interferes with the recall of new information (proactive interference). Additionally, failures may occur due to memory errors like misattribution, misinformation effect, or simply because the memory was never properly encoded in the first place, known as encoding failure.
