Can you explain how "Only a small percentage of the profits that companies make are directly attributable to good management decisions" become P-most-not DAGMD?

Hey @Alex, of course!

"Only a small percentage do" will clearly be less than half so you can transform into "most do not."

For example, only a small percentage of law school graduates do not practice law.

This means that most law school graduates do practice law.

Hope this helps! Please let us know if you have any other questions.

I know he asked that you only diagram some of the answers but dont' you think it would be useful to diagram out the answer of each question entirely. So that one does not have to scroll through literally dozens of questions to get a complete diagram of the question and the answers. Please. Its incredibly time consuming to search for the correct answer and why. Its would be considerably easier if you just have the question and all the answers diagramed out and then people can ask questions if they have questions further than that.
