Transferring text from Word to Notepad to WordPress can result in some interesting issues with layout. It looks like you just have an extra line break in between your last two paragraphs. In the Visual editor, put the cursor before the “A” in “As you can see” in the last paragraph, and hit the backspace key until you remove all the extra spaces/line breaks, then hit the Enter to add a single paragraph break. You can also fix that kind of thing with the Text tab of the editor to look at the raw code and see what got carried over from your copy-and-paste.

The best approach is to do your content composition in WordPress itself.
