Hi Kevin! Thank you for your lesson. I have a quick question - should we also write down the main point while taking the test timed? Or, is this something we keep note of in our head?

was thinking the same thing ... have you learned if there's ever an instance where the correct answer would be presented in the contrapositive form?

thank you for your reply - that totally makes sense. appreciate your help!

update - i figured it out!

#help i got Q1 correct, but i am confused by the video/written explanation of the conditional relationship. in lesson 36 the rule was that "if a conjunction occurs within the necessary condition, two events are independently necessary when the sufficient condition is triggered. " applying this rule to Q1, wouldn't an action be morally good if it solely benefits another person (or if it solely was performed with good intent)? does the logical indicator "only if" act as a caveat to this rule?

#help for the second example "If N or O is not adopted, then M cannot be adopted.," why does "cannot" not trigger the group 4 rule (pick idea and negate necessary condition)?
