How does the author make this passage particularly dramatic?

Firstly, it is very important to understand what is going on in the passage - this is the basis from which you can find your points. Once you understand how the Latin in the passage fits together, the first step is to identify any particularly strong or emotive words, more often than not adjectives, but also verbs. Do not just look for words in terms of their meaning, but also how they sound and their position as well. In terms of verbs too, you can see if the author is using historic presents (i.e. the verb is in the present tense despite it making more sense for it to be in the past tense in English) as this is a common technique used in dramatic passages. Finally, try to identify any rhetorical techniques which you can analyse, such as a tricolon or anaphora. Remember in your answer to always quote the Latin and provide a translation after it, and make sure that when you are analysing the Latin, you need to always bring it back to the question (i.e. how this adds to the drama of the passage) and not just state the rhetorical device used.
