@JenniferQin "Chess is not the most appropriate analogy to reporting on political campaigns" excludes the possibility that Chess is tied with another analogy for being the most appropriate for political campaigns. Chess COULD be the most appropriate analogy alongside another analogy.

When negating a comparative statement, you must always account for the possibility that both items being compared are equal in value and explicitly state that. I negated question 5 with the statement "There are other analogies that are as appropriate as chess OR more appropriate than chess for reporting on political campaigns." Hope this helps.
