How might history be different if one of these events hadn't happened

One way to understand what History is, is saying that it is a probabilistic science. Historians are always, even when they are not explicit about it, working with an "alternative history" in their minds, i.e., they are always asking themselves "what would have happened if...?".

That means when a historian is explaining what happened and why it happened that particular way, he/she is choosing one specific thing to be that one if it had been different, the result would be other.

For example, many historians argue the killing of prince Ferdinando I was only an excuse for the starting of a war that was already in the making for a few years. They are saying that if Ferdinando I had not been killed something else would have started World War I. The high probability of this war was already given by the tense correlation of forces between European countries in the early 20th century. Had not Ferdinando I been killed, History would still happen as it did.

If you want to know how History would be different without a certain event taking place, you should pay close attention to the historical context of the event and the direct cause of it. With this in mind, you'll be able to tell if History would have been different or not.

hr2520 is the patient's act. there is required the secretary of health to summon a committee to develop a national strategic plan of prevention. this committee has forth provisions that make possible for the govern entities to acquire private health insurance services.

is easier to keep this hr2520 as federal, because that way the secretary of health has centralized power to deal with private insurance companies and the federas government has more ways and power to negotiate with them, than doing this process state by state in their specific terms.

congress also has implied powers, which derive from the necessary and proper clause of the constitution and permit congress "to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this constitution in the government of the united states.
