Cant get LG right

AllSmiles4

Hi,

So Im averaging -8 on the LR section. There's a pattern to my incorrect answers though. They are all sufficient assumptions, principle, or parallel reasoning questions. They all require me to map out the argument and understand whats missing or to mirror the same map to something else.

The problem is that I don't understand how to map out reasoning. I can do simple ones but on my own, all my diagrams are confusing. HELP!
