This really isn't general knowledge. I typically get 100% on Bible general knowledge quizzes. I suspect that most pastors wouldn't know that Jerusalem was conquered by Babylon in 597 BC, since that date definitely isn't mentioned in the Bible. Likewise, Nabonidus isn't mentioned by name in the Bible. A Biblical scholar wouldn't be able to complete this quiz unless they were also a historian. If it requires that level of scholarship, it most certainly isn't general knowledge.
