Final answer:
An introduction's function is to introduce the topic, provide background information, capture the reader's interest with a hook, and present a thesis statement outlining the main argument.
Step-by-step explanation:
The function of an introduction in a literary essay, such as one analyzing 'The Most Dangerous Game', is multifaceted. Primarily, it serves to introduce the topic or issue at hand, setting the stage for the argument or analysis that will follow. It provides necessary background information to help readers understand the context of the essay.
For example, an introduction discussing the innovation of special effects in the movie Avatar would first explain the general history and development of special effects in film, thus preparing readers to understand the specifics of the argument about Avatar.
Additionally, the introduction should capture the reader's interest, often through the use of an engaging hook such as a quotation, anecdote, or surprising fact, and should lead into a thesis statement that outlines the main argument or analysis of the piece.
