A statement and its contrapositive are considered equivalent statements, so I wouldn't really say that there is ever a specific clue to be looking out for. Over time, you should be able to identify when an answer choice like A is taking the contrapositive of something said in the stimulus, whether it's in your head or by diagramming it out. I have found that it is something that becomes much more intuitive with practice. What I would recommend doing, especially if you're starting out, is taking (and perhaps even mapping out) the contrapositive of all statements that you see during your untimed practice until it becomes second nature. This will make you faster at deriving a contrapositive, make you faster at recognizing contrapositives, and build a habit of seeing that a statement and its contrapositive are equivalent. Good luck!

agreed!!!!!!!!

the way I see it is that Kate would not have thought that it was LC's conventions that prevented them from portraying extreme psychological states with scientific detachment. Kate herself used their conventions to tell her stories in a detached way (lines 29-34), so there is no reason for us to think that she would agree with the idea A presents. in line 20, the text also tells us that the LC wrote with scientific detachment. we might be able to say that Kate thought the LC were too focused on being nostalgic/mourning over "women's culture" based on lines 22-24 but even that would be quite a stretch.

my favorite lesson yet

I had the exact same thought process ://
