premise: Tonight the topic will be domestic affairs, but the format will be the same as that first debate. I'll moderate our discussion under detailed rules agreed to by the candidates, but the questions and the areas to be covered were chosen by me. I have not told the candidates or anyone else what they are.
hypothesis: the candidates or anyone else  know what they are in the office. 
  
reason: I have not told the candidates or anyone else what they are. By adding the word to the office we don't know if they know or not what they are in the office, so the statement could be neither definitely correct nor definitely incorrect
