Skimming through or scanning other the reading material
To understand how or why the things are happening or why the person feels the way they do about the situation
Answer:
Paragraphs are beneficial because not everyone reading want to read the whole thing, some people are looking for a specific evidence or a specific topic that is somewhere in a written information. With paragraphs it is easy for someone to understand and get what they need or want to read, just by skimming the paragraph and reading the first sentence of each paragraph.
Apprehension is best defined as a feeling of anxiety or fear that something bad will happen.
