Does anyone have recommendations for supplemental materials in reviewing valid and invalid argument forms?
I started the sufficient lesson today however I realized I need to go back and review the prior lessons. I did not locate a 7sage webinar on validity, any suggestions in addition to reviewing the valid and invalid lessons?
@beezmoof JY didn't list the first sentence as a premise but I did diagram this as a premise when trying the problem, as follows:
Science → / Explain emotions
Everything after "such as" in the first premise defines what the emotional phenomena are but it's not crucial in this problem because neither frustration, love, or being moved by a painting is used in the rest of the argument. It's just there for context and to throw people off. They're not even listed in the AC's.
The following sentence starts with referential phrasing, "Since they" so the first sentence supports the last because without it, we don't know what "they" is (emotional phenomena).
So before you try to identify the SA, the diagram is as follows:
(first sentence) Science → / Explain emotions
(first part of second sentence "SINCE" indicator) Emotions → /explained by PCN
(CONC.) Emotions → /phys. phenomena
We may draw a valid conclusion (using valid argument form #6)
/explained by PCN ←s→/phys. phenomena, take the contrapositive to the get the right answer:
E) Phys. phenomena --> explained by physics, chemistry, etc.
