I understand the whole formal logic chain, pretty simple, however I do not understand why the last sentence is added to the end of the chain (a necessary condition) when the sentence starts out as 'The only', which implies sufficiency. Not sure for legal reasons if I am able to post the actual question on here, but I am more the welcome to if somebody if willing to assist me. Thanks!

Admin note: edited title; please use the format of "PT#.S#.Q# - [brief description]." Also, you are correct - please do not post the entire actual question in forums for LSAC/legal reasons, the title format helps others reference the PT and question. Thanks!
