Explanation:
In writing, there are different organizational structures writers can use depending on their topic, focus, and purpose. Below I explain some of these structures:
Spatial: This organizational structure is mainly used if the author needs to describe the relationship between objects or elements in space. Due to this, the spatial structure uses words such as north, below, east, on, etc. and it is common when a place is described. In this context, this is the structure used by Elizabeth because in her text she will describe a place.
Chronological: This organization structure arranges information according to time. It includes elements such as years, words such as before, after, or steps. Moreover, this can be used for historical events or processes that require steps. In this context, this is used by Kent because writing instructions implies organizing the steps according to the time these should occur.
Compare and contrast: This organization structure implies analyzing two elements of the same category, for example, two national parks, and highlighting their differences and commonalities. Due to this, this organization structure is used by Robert because by analyzing two options he can show the audience the advantages and disadvantages of each, and later the audience can show its preferences.
Categorical organization: This organization groups ideas according to different topics, sub-topics, or categories. For example, in a text about animals, these can be described according to mammals, reptiles, insects, etc. Moreover, this is the organization used by Charity because she will organize ideas in categories or topics.
