Answer:
Separate the entry from any other existing entry by using a new line or an indentation.
Explanation:
A diary entry can be anything. Personally, if I were to write a diary entry, it would be a recount of something important from my day. The content of the entry will create the form.
The use of a paragraph is simply a way to isolate or separate the ideas from within the entry.
So if you were to create a diary entry using a paragraph, simply use something to separate the entry from other existing entries, such as a new line or an indentation.
