Final answer:
When merging list entries, the field on a bad entry should be changed to the value on a good entry, depending on the situation and purpose of the merge.
Step-by-step explanation:
When merging list entries, the field on a bad entry that should be changed to the value on a good entry depends on the specific situation and the purpose of the merge.
For example, if you are merging a list of student records and one entry has a misspelled name or incorrect email address, you would typically update the corresponding field on the bad entry with the correct value from the good entry.
However, if the merge is based on a specific rule or condition, you may need to change a different field. It's important to analyze the data and determine which field is appropriate to update for each merge.
