Hi Roberto, thanks for the question.

I think this question, while it can be diagrammed, actually ends up being more complicated compared to just reading it and trying to understand what we can.

We would probably start diagramming this one and have some difficulty making connections and this would signal to us that maybe we should abandon that approach in the moment.

However, if we did choose to diagram it, it can look something like this.

Burn huge amounts of trash in incinerators -> waste natural resources -> wrong
NOT wrong -> NOT waste natural resources -> NOT burn huge amounts of trash in incinerators

Trash recycled -> fewer resources wasted -> NOT incinerator built
Incinerator built -> NOT fewer resources wasted -> NOT trash recycled

Answer choice D is just the contrapositive of the second part of the first sentence.

I hope this helps. Please let me know if you have any other questions!
