Managerial jobs may merit local advertisement while semi-skilled jobs may only require national advertisement for job ads.

The statement in the question suggests that managerial jobs often need to be advertised locally, while semi-skilled jobs can suffice with national advertisements. However, the correct response indicates that this is not necessarily accurate.

In practice, semi-skilled jobs may also benefit from local advertising, particularly if the skill sets are in demand within a specific community or region. Local advertising can help employers find candidates who live nearby and are more likely to apply for roles that require less specialized skills.

On the other hand, managerial positions, while often more specialized and potentially necessitating a narrower skill set that could be found locally, may at times require wider-reaching advertising. This is especially true for industries or organizations that have specific criteria for management roles, as candidates with the desired backgrounds and experiences might not be located in the immediate vicinity.

Thus, because both categories of jobs can have varying requirements for advertisement depending on local market conditions, availability of candidates, and specific job needs, the statement that managerial jobs only require local advertisement while semi-skilled jobs can be advertised nationally is not universally true. Therefore, the answer to the question is that the statement is false.
