The reason why the Crusaders were so successful in the first Crusade was that the Turks were already weak from fighting themselves - B.
Contrary to common thought, at the times there was no single unified muslim resistance that was fighting the Crausaders, at least in the beginning. There were a lot of fractions that were fighting between themselves and against the Crusaders.

Hi!
A state has all of those characteristics except an ethnicity. An ethnicity is something which belongs to a person or group.
While a state may have groups of people who belong to certain ethnicities, a state itself does <em>not </em>have an ethnicity.
Hopefully, this helps! =)
