I've read the full Formal Logic PDF and am working on the drills and reviewing with Answer Key. On #8 of the Drill: Diagramming and Making Inferences, I incorrectly wrote the diagram.
I used abbreviations of: SH (students in Henry's class), A (grade A), B (Benson award)
My diagram: SH A B
Because of the "at least 1 A" I interpreted the 2nd statement as: A B. The PDF indicates that "at least 1" indicates Some. So I'm confused as to why the diagram is written as: Every A is B (A B).
Because I wrote the diagram incorrectly I wrote out an incorrect inference of: SH B. Which I now realize is incorrect because we can't infer from a "Most" to "Some" diagram, correct?
Can someone please point where I made the mistake.
Thanks in advance!
