Which of the following sources is least likely to have been edited for accuracy?

I would say that a personal website would not have been edited, since no editor is needed to publish. While in a newpaper, encyclopedia, and book, an editor always makes sures that they fact check to ensure that the people are reading credible information.

Hope this helped!

The answer is    "illustrate why one's dreams need to be pursued in a logical order if success is to be obtained"  so c is the answer. : )
