Earlier this week during a Sage/Instructor chat on Discord with Jonathan, argument structure came up. The following link is the only list of LR questions I've been able to find with argument structure. This list mainly groups LR questions by flaw type (circular reasoning, false binarism, appeal to authority etc). If you CTRL+F you can search by "correlation/causation" for that subset of phenomenon/hypothesis questions and for conditional logic search "formal logic" or "necessary/sufficient". This is the closest thing I've found to a list of LR questions per PT by argument type. http://www.top-law-schools.com/forums/viewtopic.php?t=108425
