"Moreover, no applications have been found for grades of plastic that are lower than the currently lowest commercial grade."
rule: pick a variable and make it sufficient, take the other variable and negate it.
Since it says "no application" don't you negate the no?
LGP -> Application

Hi, we do not negate the no. When it comes to diagramming and understanding conditional statements, I would recommend using common sense as a check. You have lgp-> application. In other words, you are saying for the lowest grades of plastic there must be an application. This is the opposite of what the passage said. For no statements more generally, (e.g. no xs are y) we can assume these two things are mutually exclusive, so if one happened then the other cannot have happened.
