Which part of the video is giving you trouble? Let me know and I'd be happy to explain further!

@mresende, maybe I can help.
A principle is a general statement that an author makes, whereas a conclusion is the specific claim that an author argues. The author uses premises and often principles in order to support the conclusion. You are usually able to identify the conclusion through specific keywords (i.e. therefore, hence, thus, so, it follows that, etc...) and by asking yourself if everything else in the passage supports this claim.
Does that make sense? Best of luck with your studies!
