Final answer:
In this question, 'cross reference' refers to comparing and matching names from different sources or indexes in order to index them in a specific manner.
Step-by-step explanation:
In the context of the question, the term 'cross reference' refers to the process of comparing and matching names from different sources or indexes. In this case, the names are being cross referenced in order to index them in a specific manner.
For example, let's say we have a list of names in one index and a separate list of names in another index. To cross reference these names, we would compare the names from one index to the names in the other index to find any matches or similarities. Once we have identified the matching names, we can then index them in a specific way, such as alphabetically or by category.
So, in summary, the task at hand is to compare and match names from different sources or indexes and then index them in a specified manner.
