Management reports that an unacceptably large number of cases are incorrectly identified as potential duplicate cases. Which two approaches can you use to modify the duplicate case search process so that the process produces fewer invalid duplicates?
1) 1. Implement a more accurate algorithm for identifying duplicate cases.
2) 2. Increase the threshold for determining duplicate cases, reducing the chance of false positives.
3) 3. Reduce the threshold for determining duplicate cases, increasing the chance of false negatives.
4) 4. Increase the number of comparison factors used in the duplicate case search process.
5) 5. Decrease the number of comparison factors used in the duplicate case search process.
