Excerpts 1 and 2 are expository texts.
Expository texts contain a main idea with supporting details and evidence. They should have a conclusion as well. Excerpt 1 informs the audience about Mount St. Helen. Excerpt 2 explains how anxiety manifests and ways to reduce it. Excerpts 4 and 5 are stories. They do not make a claim and then back it up with supporting evidence. Instead, they describe characters, a setting, and events. Excerpt 3 is written in second person point of view and explains about visiting another country.
