Confusion of Necessary with a Sufficient Condition

juneby01

I have trouble recognizing these sentences in the LG sections I know they are fallacies, but how do I know a sentence is a sufficient not a necessary condition or vice versus ?

If you have access to the core curriculum, there's an entire section that covers this. For LG, there's essentially a list of words that indicate whether something is sufficient vs necessary. If study the list of words, you should be good for LG. As for LR, it's sometimes a bit more fluid as the English language can be a bit tricky and you'll have to rely on your familiarity with conditional language to parse out tougher sentences.
