Are you sure that the text doesn't have end-of-line characters imbedded in the text, ie that there is not a carriage-return and/or line-feed characters at the end of each of the lines that don't let the text go all the way to the right edge of the window??
Try the following to see - in a Terminal.app window (Terminal.app is located in the /Applications/Utilities folder):
cd "folder-name-where-file-is-located"
od -cx "file-name"
For example in the first line your screenshot shows the line ending in "has been" - do you see anything after the "has been" in the output, for example \n or other end-of-line type characters or is the "has been" followed immediately by the first words of the next line? Does this make sense??
Good luck - if you need more help in using the Terminal.app program please ask, as it can be kind of awkward to use until you get familiar with it.
