Rats learned that they can escape through a hole when a particular visual stimulus is present. the rats were placed in an arena that had an escape hole leading to their home cages on one side. the home cage contained a drop of condensed milk, a rat favorite (rossier, grobety, and schenck, 2000). this best illustrates learning.

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.
