Hi @Aidyn-Carlson,

"LI" = nations that have little interaction with one another.
"LK" = little knowledge of one another's needs and problems.
"SJ = sympathy and justice.

First premise tells us LI - > LK. Second premise tells us. SJ - > ~LK. We can take the contrapositive to get LK - > ~SJ, which also gets us LI - > ~SJ. We see that this matches B. Hope this helps.

@Shunhe Can you explain how you diagrammed the correct answer? Doesn't "without" act like "unless" in which case LI would be necessary, and SJ would be negated in the sufficient?
