Which of the following must happen for a state to nullify a law

There is an existing legal theory in the US legal system that a State would always have the last say in enacting laws even inforced by the federal government. This legal concept is known as nullification. However, the condition to nullify a federal in a State would be first, for the State court to prove that the law is unconstitutional. Then a legal process has to be done so that the State law can prove to the federal courts that the law enacted and imposed by the federal government is unconstitutional. 

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
