The excerpts that function and can be characterized more accurately as expository texts are the first three excerpts: Excerpt 1, Excerpt 2 and Excerpt 3. These excerpts are centered around the communication of knowledge, of information which the reader may not have. They are exposing these 'new' information with short and regular sentences that strive to be as clear as possible. It can be discussed if the Excerpt 5, taken from Charles Dickens' <em>Great Expectations</em>, is an expository text, seeing as it has a very nuanced description; but it would be more precise to consider that excerpt as a descriptive text, as a type of text related to narrative fiction.
