Question #1099

Sufficient and necessary confusion

I do not understand why a scientific theory being a good theory is not the necessary condition here. When I read, "A scientific theory is a good theory IF it satisfies two requirements," I understood that as an if-then statement that could be reworded, "IF it satisfies two requirements, THEN a scientific theory is a good theory. The S&N would then write as: ADLCO and DPAR --> Good theory I then came to the conclusion that A is correct with this background work. Can you explain why it is the other way around for the S&N?

    Hi @kat85390, Happy to help! This is definitely a bit confusing. It seems like the LSAT writers have tried to trick you here with the inclusion of the word "if." What the stimulus is actually saying is that there are two requirements for a scientific theory to be good. In other words, there are two necessary conditions/"if a scientific theory is good, then it satisfies these two requirements." Hope this helps! Please let us know if you have any further questions.
