Tomorrow, five different terrorist groups (Al-Qaeda, Hezbollah, Hamas, Islamic Jihad, Asbat Al-Ansar) will attack five different Canadian targets (CN Tower, Parliament Buildings, Confederation Bridge, Port of Montreal, Vancouver Ferry Terminal) with five different kinds of weapons (explosives, fire bomb, nerve gas, radiation bomb, anthrax powder) at five different local times (9 a.m., noon, 2 p.m., 5 p.m., 8 p.m.). From the clues given, figure out which group is hitting which target with which weapon at what time. (Ignore time zone differences.)
