Confused with diagramming,

Ok so I diagramming the last sentence like this: A - >not LPG (lowest plastic grade) Is this wrong? I noticed in the video it was diagramming differently and I was set on finding the keywords which I used since it was a "no" statement

Hi, I didn't get an answer.

Remember, you must always take a Sufficient & Necessary statement in context. What is the last statement doing? It is giving us information about plastic that is lower than the currently lowest commercial grade.

We are told that this type of plastic has no application. The way you have written the statement means that anything that doesn't have an application is a plastic that is lower than the currently lowest commercial grade. But, that is not what this statement is saying, nor is that true. Something that doesn't have an application could be chemically derived aluminum, or overly recycled mulch.

In context, we are given information about this certain type of plastic. Thus, we diagram it: LPG ==> not A.

Hope that clears things up! Please let us know if you have any other questions.
