#feedback the explanations for this skill builder are a bit confusing and hard to follow along. It's a bit discouraging after all those lessons and everything not making sense when reaching the skill builder. I don't think the lessons previous to this set me up well. Just some of my thoughts.

can you explain further? I am having the same issue

These skill builders are great for identifying sufficient and necessary causes but I am having trouble making valid inferences. So I made up an example, please let me know if I am on the right track. For question 4: lets say Amy has 18 books overdue, we can make a valid inference that she will be fined because it triggers the necessary. However, if the premise is Amy is fined, we cannot make a valid inference that she has more than one book overdue because the rule says having more than one book is sufficient to be fined, but it doesn't say it’s the only reason someone might be fined.

agreed

This lesson was very confusing :/
