I do not have your choices of "the following" Here are some reasons I learned: Christianity, empire was too big and became hard to manage, there were many nonromans attacking parts of empire- Goths, the emperors themselves were weak or insane intrigue was rampant.
C.the revolution was an attempt to break free from the motherland and create a new nation.
I believe the answer would be C, burning fossil fuels. Oil and gas is made up of the remains of microscopic plankton. Over millions of years the remains become the carbon-rich coal, oil and gas we can use as fuel. When fossil fuels are burned they release carbon dioxide into the atmosphere, thus contributes to global warming.
We need to recycle.IN order for climate change
Many Japanese soldiers were killed in battle of Iwo Jima because:
1) Their shinobi code of honor: They had a some 'rules' they had to follow. One of which was that they could not be captured. If they were wounded, they would have to suicide, and it was particularly better to take their own life when the enemies were around.
2) Because of this, they did not have respect for any Allied soldiers that surrendered. This made the Allies wary of the Japanese, and fought the Japanese with a different "rule" then their German counterparts. In fact, some soldiers adopted the motto "shoot before you ask questions", and it was used widely in battles. This motto meant that they would accept no prisoners.
3) Iwo Jima was considered to be part of the Japanese homeland that was born out of the ocean when the Japanese god created the world. To them, this land was sacred, and they said & thought that these lands would never be conquered. This was part of the reason why many soldiers fought to the death, because they believed that their Islands would never be taken over by foreigners.
fun fact: Kamikaze, meant divine wind, and it was widely used by the Japanese during the war, even on Iwo Jima. In the history before WW2, a group of Korean ships set sailed to attack Japan (back in the Samurai ages). However, they met strong winds and storms, and the attack force was destroyed. The Japanese named this kind of wind "<em>kamikaze</em>".
hope this helps
