Final answer:
When describing vehicles and persons, it is false that details not known should be omitted without comment; it is more professional to note information as 'unknown' or 'not available'. Therefore, the correct answer is b) False.
Step-by-step explanation:
When describing vehicles and persons, particularly in a legal or official context, there is indeed a standardized order and method to relay the information. If some details are not known, it is not advised to simply omit them without comment.
It is generally better to explicitly state when specific information is unavailable, which maintains the integrity and completeness of the report or description.
Hence, the answer to the question about whether information should be omitted without comment when not known is false.
In official reports, stating 'unknown' or 'not available' in place of missing information can be seen as a more professional approach.
