How to know when to diagram?

Hello @aimee.marisa, Remember that we use the terms "sufficient and necessary" to describe conditionality. To put it simply, this is the language of if/then statements. But, as you seem to understand, conditional statements are not always written in the if/then format. In the question that you commented on, I didn't see the type of conditional reasoning that is helpful to diagram. I thought of it as two competing arguments. Some environmentalists believe one thing, other environmentalists believe something else. I suppose you could make a conditional statement out of the first group's argument: If there is no economic benefit (not EB), then we should not exploit the environment (not EE). not EB - - - - - - -> not EE EE - - - - - - - - > EB However, once you get to the answer choices, you will see that this is not particularly helpful. Also, we don't have to accept this as true. The stimulus only claims that some people believe this. I'll create some sentences with sufficient and necessary indicators. I do not have an exhaustive list, so you should also look at the flashcards under the sufficient/necessary lesson. Unless: Unless the bear population is back to normal (BPN), we should support the conservation bill (SCB). not SCB - - - - - > BPN not BPN - - - - - > SCB Only: Only park rangers (PR) are allowed in the forest (AIF). AIF - - - - - - > PR not PR - - - - - -> not AIF Every: Every species in the mountain range (SMR) is endangered (E). SMR - - - - - -> E not E - - - - - - -> not SMR No: No mountain lions (ML) will hunt in the daytime (HD). HD - - - - - > not ML ML - - - - - -> HD Here are some other indicator words: Without Any All If and only if Never

Thank you very much! That helps a lot!

Hi Sam - just to clarify, does "no" always indicate a Necessary Condition?
