Final answer:
The accuracy of using 'Smith' as the first indexing unit for Janine Smith-Jackson depends on the specific legal indexing system's rules. Compound last names may be indexed under either part of the surname or as a whole, and this practice varies across different databases and legal systems.
Step-by-step explanation:
The statement 'The First Indexing Unit For Janine Smith-Jackson Is Smith' suggests a legal indexing convention, likely referring to the way names are indexed or organized in legal documents. In many legal databases and documents, individuals' names are indexed by their last name. However, for compound last names, such as Smith-Jackson, different systems may have different rules.
Some systems would index under Smith, while others might index under Jackson, or even Smith-Jackson as a single unit. It's vital to consult the specific guidelines of the legal indexing system in use. So, without additional context about the specific indexing rules in question, it is not possible to definitively say that the statement is true or false. It depends on the rules of the specific database or legal system being referenced. As general practice though, it would likely be false as most indexing systems would either choose Jackson or index the entire compound surname together.
