The correct answer is by exploring human emotions.
Elizabethan drama placed a lot of emphasis on portraying human emotions, how people thought and felt about certain things. Shakespeare was definitely one of the authors who was best at doing that, through plays such as Hamlet, Macbeth, etc.
Religion wasn't that important during the Elizabethan era, so options B and D are incorrect. And if you read the excerpt, you will see that there is no mention of political policies, so C is also incorrect, thus leaving us with A.
The answer is: it is about evolution.
Darwin himself characterized his seminal book, <em>On the origin of the species, </em>as “one long argument”. There is still debate as to what exactly did he mean by that characterization, but it is agreed upon that he evidently was referencing his theory of evolution based on common ancestry between species and natural selection as the process of differentiation between them, which, all in all, tells a story that took millions of years, or, in more poetic terms, it summarizes a very long argument.
