No, it was just a really hard quiz. I've read both the Lord of the Rings and the Hobbit multiple times, and didn't remember several of the specific details included in this quiz.
In letters to Rayner Unwin Tolkien considered naming the two as Orthanc and Barad-dûr, Minas Tirith and Barad-dûr, or Orthanc and the Tower of Cirith Ungol.
However, a month later he wrote a note published at the end of The Fellowship of the Ring and later drew a cover illustration which both identified the pair as Minas Morgul and Orthanc.
It's a grey area which two towers are the actual "two towers", as I'm fairly sure that Tolkein never explicitly said so. I remember Peter Jackson talking in the film appendices about it as well, at one point, saying that it was a grey area.
I think many people assume it is Orthanc and Barad Dur, because in the films, Saruman talks about the "Union of the Two Towers" whilst the camera is panning up Barad-dur, and obviously Saruman is in Orthanc...
The two towers could equally be any of the others that people have mentioned (Cirith Ungol, etc) so I'd accept multiple answers, or just remove the question altogether.
I'm not keen on that Saruman question. At one point he says "I am Saruman of Many Colours", and Gandalf remarks, "I prefer White". It's not like everybody refers to Saruman throughout the remainder of the book as "Saruman of Many Colours". If we're looking for a different name for Saruman, I would have hoped Sharkey would have worked, particularly when that's mentioned in another question which I also thought was unfair for different reasons.
