Is this statement ever a possible answer? OR is this answer a self-contradictory statement.
"A factor that need not be present in order for a certain effect to arise may nonetheless be sufficient to produce that effect. "
Is this just saying it doesn't have to be sufficient but may nonetheless be sufficient...?
I'm just confused to this answer choice, what does this even mean?
Maybe try a different approach for the questions? It's easy to look at the questions by trying to understand what it's saying, but maybe start by analyzing the structure. (is it comparing? attacking a study? Conditional reasoning?) And find certain types you can answer quickly to leave some leeway to spend more time on the questions you're missing!
