“This” is an idea. It’s the sentence before the quote. “This” is investigating an error’s cause and making changes to prevent the errors. I get it more now what a postmortem is. I thought it was just investigating the cause of the errors. I definitely would want to make the changes too. Otherwise, why am I investigating so much?
What are root words btw? I think I remember those from school. I remember words like suffix and prefix. I think those are root words. Imma look it up rq…Ok after looking it up I figured “post” meant after and I looked up “mort” which I found out was death. Those are the root words
