Final answer:
The re-establishment date of the UF Chapter cannot be determined without further context on which specific chapter within the University of Florida is being referred to.
Step-by-step explanation:
The question refers to the re-establishment of a particular chapter or organization but does not provide sufficient context to determine which exact chapter is being referred to. Without further context, it is not possible to give an accurate date for when the UF Chapter was re-established as 'UF' could refer to any number of chapters within the University of Florida.
It might be related to organizations such as the Gatorade team which was notably tested by University of Florida football player Chip Hinton in 1965, or it could pertain to another organization such as LULAC, which was founded in 1929 and has chapters across the United States.
For more precise and accurate information, additional details specifying the UF Chapter in question would be necessary.
