Final answer:
The question about positional dispatch is not clear as it lacks context or information, and positional dispatch is not a term typically associated with the subjects provided. Further details are needed to give an accurate answer.
Step-by-step explanation:
The question you've asked about positional dispatch strategies and preferences seems to be out of context or lacking information, thus making it hard to provide a specific answer. Positional dispatch is not a term commonly associated with any of the subjects listed (such as Mathematics, History, English, Biology, etc.). Therefore, without further context or a clear understanding of the specific field or subject matter you're referring to, it's not possible to accurately determine the best evidence and reasoning to support a position, nor to outline the strategies involved.
Questions about positional arguments or dispatch mechanisms are more typically found in computer programming and technology discussions, specifically in the context of function calling conventions. If this is indeed the context you are referring to, please provide additional details so that an accurate and helpful response can be given.
