It is really important to note that you do not know anything that happened after those specific dates for each debate (related to the issues themselves or even more generally e.g. avoid mentioning things such as inventions which happened after that time etc...) - your job is to engage in solving those problems given the conditions and knowledge of the precise time in which you are having the debate.
