The actual group of people in the back of the room who have opinions and ideas all their own are known as the literal audience.
Literal audience refers to the type of audience who listens to the speaker's message. For instance, if speech is uploaded to the internet, then the audience would be who views it.
In the section "Pathology Indicates Manner of Communication," Snow explains the nature of cholera and argues that the study of the disease will help scientists understand how it spreads and how it can be averted. He combines his knowledge of the characteristics of the disease with his clinical experiences to build his argument.
He continues to build his case through other sections of the essay. For example, in "Cases Proving Person to Person Transmission," he provides evidence from other cases to support his theory that cholera is spread between people. Then, in another section, he maps an outbreak that occurred on Broad Street, connecting the affected individuals to a single water pump. After making these supporting arguments, he arrives at his main argument that cholera spreads through contaminated water.
In sum, Snow discusses a different concept in each section; these sections complement one another to build a complete, effective argument. The section labels help the reader follow Snow's line of thinking by mapping the main points.
When life gives you lemons, make lemonade!
If life were predictable it would cease to be life, and be without flavor.
Life is an experiment. The more experiments you make the better.
Life is short and its up to you to make it sweet.
