@DurodoluwaAina I may not be a whole lot of help as I am early on in my studies, but I have noticed that with many of the intermediate conclusions, you can put one of the conclusion indicator words before it and it still sounds alright. "But lately factories upstream began dumping waste into the river (Premise). Therefore/So, the river water is no longer safe to drink (intermediate conclusion)." Many of the intermediate conclusions already have these in them too. I hope this helps I am not very knowledgeable on this yet.
