Derek Parfit's survival idea compares the self to: a supercomputer God a never-changing blueprint a chain-link fence

The correct answer is **a chain-link fence**.Derek Parfit argues against the notion of a single, unchanging self. He believes personal identity is not about some indivisible soul or ego but rather a complex series of overlapping psychological connections (memories, beliefs, desires, etc.) over time. He uses the analogy of a chain-link fence to illustrate this. The fence is made up of many interconnected links. If you remove one link, the fence is still essentially the same fence. Over time, many links can be removed and replaced, and the fence still persists even though none of the original links remain. Similarly, our personal identity persists over time despite constant psychological change. We are not a single, unchanging entity but rather a collection of interconnected psychological states.
