B will go to the party unless M goes.

I really struggled with this question as well and the whole idea of "unless". I found this article that broke it down in a way that makes sense. [url]https://testmaxprep.com/blog/lsat/the-unless-statement

Basically, the idea is expressed with this example.

A unless B.

The necessary condition is B. The sufficient condition is not A.

So if it is rewritten as: "If not A, then B". We can say ~A --> B or the contrapositive of ~B --> A which is exactly the same logic that this applied here.
