If checks and balances didn't exist, there would be nothing stopping a group i.e. the president, from making whatever laws they wanted.
In essence, if there are no checks and balances, government is no longer a democracy because nothing prevents the group in power from doing what they want. For example, a president that wasn't checked by the opposition party could pass a law saying that they are legally allowed to be president until they die, and nobody would stop them.
The life of a civil war soldier was harsh because in the summer and spring you would have hot and dreading because of the humidity and the heat of wearing long sleeves, and warm during the fall, freezing in the winter and horrible in a battle because of all the smoke in the air from gun shots. <span />
He was an activist you can say, he urged for the colonies to win independence because he thought it would be common sense
The modern development of today's world would have first made the routes safer. Today we have the safety of common things such as police officers, hospitals, e.t.c. Transportation of goods would have been easier, and it would have been easier to carry larger amounts of goods at one time.
hope this helps :)
