How to diagram the Quantifier and S->N Stmts
Hello,
Can someone please explain how to diagram this question? There is the quantifier, "Most", and the sufficient/necessary statement stating "every.." but I'm not sure how to combine them to make a valid conclusion.
If this question shouldn't be diagrammed, how would I find the correct answer?
Thank you so much!

Thank you for your question. We can diagram these statements in the following way.
We cannot use transposition on "most" statements but we can reverse a "most" statement to infer that: ~violate environmental regulations some-> Velyena
Some mines that never violated environmental regulations are operated by Moradco in Velyena.
Gold -> violate environmental regulations We can infer that if a mine has not violated regulations, it is not a gold mine. ~violate -> ~ gold
We can combine both premises to conclude that:
Velyena most -> ~violate -> ~gold which is equivalent to: Velyena most -> ~gold
Most of the mines in Velyena are not gold mines (D).
