Rudiments (ARC Bks, PTPs, M/W/Hs) are usually not necessary in correcting a list as a wrong list usually is the ARC Bk and PTP.

To correct a list ask the pc or pre-

1. “Is it an incomplete list?” If it is, extend it and find the item.
2. “Was it the first item on the list?” If so, indicate item to pc or pre-.
3. “Was it an unnecessary action?” (dead horse). If so, indicate it.
4. “Had you not answered the listing question?” If so, re-clear question and if it reads list it.

The 4 basic reasons for a wrong list are here:-

1. It was the first item.
2. It is not a complete list.
3. The question didn’t read (which causes a dead horse).
4. The pc didn’t answer the question.
