What are two tools used by authors to ensure that the way in which they present information is both coherent and accessible?

Coherence in literature refers to the consistent connections between ideas and/or events that allows the readers to make sense of the narrative. Along with cohesion, which is the flow of sentences and paragraphs that holds a text together, they make the text accessible and clear. Coherence is about how the author develops the argument, and coherence is about the gramatical aspects.

One of the tools used to make sure the text is coherent is the repetition and cross-referencing of a key term or phrase throughout the text. Another tool is the use of transitional words to connect one sentence to another, such as "in addition", "then" or "but".

no its not a run on sentence however i think you meant wet suits not sours also a run on sentence would be like surfers surf all winter long in southern california by using wet sours to keep them warm and the live their all year long  

the author is intending to draw attention to the plight of refugees, editorial and biography support this. both workpieces make the reader empathize with enrique as well as with the other young migrants from central america. the writer, however, is using a different approach to each text.

the editorial includes strong words to persuade readers. he is trying hard to convince readers in the us to change its refugee approach.

the biography relies on narrative techniques and figurative language which the writer uses wisely in the setting, characterization, and personification to educate readers on the topic.
