The trace-over alteration method is most often used to change what?

The trace-over alteration method is primarily used to change numbers on documents. This technique involves tracing over existing numerical information to modify it without significantly altering the original document's appearance. It is particularly effective in situations where precise modifications are necessary, such as in financial documents or official records where numbers hold critical importance.

The other options, while they may involve alterations to documents, do not commonly employ the trace-over method in the same way that numerical changes do. For instance, altering a name might involve different methods, such as erasure or complete replacement, rather than precise tracing. Gender alterations can often require a more complex approach, typically handled through legal procedures rather than simple modifications of the text on a document. Lastly, seals usually require physical alteration or replacement rather than tracing due to their significance and the need for authenticity.
