@RyanAlexander That actually does help! thank you sm!!

So I could be wrong but the Kumar argument was invalid because he was 15 min late and not 5 min late? because it said ONLY IF they arrive more than 5 min past the ring? are we saying its invalid because we don't know what happens if hes 15 min late? Sorry if this is a silly question !

Not sure if this is just me however, all of these lessons are helpful however, this one just fully lost me. Not to mention when I try to apply these to the actual questions it just takes to long and I end up confusing myself and overthinking.

@eborland I could be wrong but I think thats the point of these drills. You should be able to find the conclusion even if it is not in the start or the end of a sentence.
