The statement that best describes a cause-and-effect structure of a speech is:
"It presents the reasons something happened and describes the result."
In a cause-and-effect structure, the speaker explains why something occurred (the cause) and what happened as a result (the effect). This helps the audience understand the connections between events or actions. By presenting the reasons behind an occurrence and its outcomes, the speaker can make a persuasive argument or provide a clear explanation of a phenomenon. This structure helps in logically organizing information and illustrating relationships between different elements in a speech.
For example, if a speaker is discussing the impact of climate change, they may present the causes of global warming such as greenhouse gas emissions and deforestation, and then describe the effects like rising sea levels and extreme weather events. This cause-and-effect approach helps in conveying complex ideas in a coherent and understandable manner to the audience.
