The document contains examples of different types of documents: a magazine article on evolution from National Geographic, IKEA instructions, a WikiHow guide on how to toast bread, and a university prospectus from York University. The National Geographic article uses formal language and provides evidence supporting evolution, while also acknowledging bias. The IKEA instructions are concise and use only images to avoid ambiguity. WikiHow guides are also concise but can be ambiguous due to unclear images sometimes. University prospectuses aim to impress readers and promote the university using both clear information and informal language.
