Answer:
Conclusion.
Step-by-step explanation:
The structure of a five-paragraph primarily includes three basic elements i.e. introduction followed by the three-paragraph body and the conclusion. Firstly, the introduction functions to grab the readers' attention and inform them about the key idea or argument of the essay. After this, the body paragraphs function to elaborate on the idea, its significance, and substantiate it. Lastly, the conclusion is made for summing up the essay and restating the main points to show how the ideas have aptly supported the thesis. It assists in upholding the central idea in readers' mind and make the closing remarks that readers must keep in mind.
