Which best describes the purpose of a control sample?
a) to have more quantitative data to analyze at the end of the experiment
b) to have more qualitative data to analyze at the end of the experiment
c) to compare its results to those of a well-known scientist
d) to compare its results to those with the experimental sample

The correct answer for this question is D - the best way to describe the purpose of a control sample is to compare its results to those of the experimental sample. The control sample is compared to the results in which the independent variable was changed, which therefore allows a scientist to better understand the effect of the independent variable.

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.
