The correct response is:
**A binary search only works on sorted data structures, but linear search can work on any.**
### Explanation of Differences:
1. **Data Structure Requirement**:
- **Linear Search**: Can be performed on any dataset, whether sorted or unsorted.
- **Binary Search**: Requires the dataset to be sorted before it can be applied.
2. **Time Complexity**:
- **Linear Search**: O(n) in the worst case, where n is the number of elements in the dataset.
- **Binary Search**: O(log n) in the worst case, which is much faster on large, sorted datasets compared to linear search.
3. **Implementation Complexity**:
- **Linear Search**: Generally simpler to implement; involves a straightforward traversal of the dataset.
- **Binary Search**: More complex to implement; requires knowledge of how to divide the dataset and manage indexes.
4. **Performance on Large Datasets**:
- **Linear Search**: Slower as the dataset size increases, since it checks each element one by one.
- **Binary Search**: Significantly faster for larger, sorted datasets due to its logarithmic nature.
