where "key issue" means "an issue that gets the NYT editorial board hot and bothered." (Hint: none are labeled as concerning Manicheanism or Transubstantiation or the Apostolic Succession.) Unsurprisingly, two of the six "issues" are pelvic. The sequence of the "issues" is also revealing of NYT priorities.
However, TOF is unsure whether the quiz proves the ostensible point. It depends on how clueless the NYT people are. See what you think. Perceptive TOFians should get high marks based on form rather than matter.
