Having no context and never having been to Australia, I would assume that there is a lack of opportunities for proper "brick and mortar" based schools for some areas of Australia.
Again, no context and no first hand knowledge of the continent...so, take it as you will.
C. citizens united v. federal election commission :)
The answer is: Lincoln claimed to defend the Union and attempted to convince the South that the secession was illegal and impossible.
Lincoln gained massive popularity on the northern states because he advocated for the establishment of slavery, and the south was threatening secession because they relied heavily on slavery as the major workforce that sustain their economy.
Lincoln realized that if the southern states manage to secede from united states, The republican party would receive the largest amount of blame for the separation, and their chance to free the slaves in southern states were gone. Because of this, he swore an oath to defend the union and prevent the south from seceding in his inaugural address.
Constitutional Convention! A Constitutional Convention is a gathering with a purpose or writing a new constitution or revising an already existing one.
