place holder vs. summary column

Hello,
I ran into a test question that I don't quite understand, and I hope you experts can help me out a bit. The question:

Which type of column would you use to store the names of the regions with the largest and smallest total salery values? Answer (relevant ones)
- Place Holder

• Summary

According to the questions makers 'Place Holder' is the correct answer with no explenation. My questions is why?

I thought Summary was correct because it allows you to change the property pallette and easily get the largest and smallest total saleries.
--> Where do I go wrong in my thinking?

Thanks a lot,
Pieter
