It's a bit confusing, isn't it!
It looks to me like you are translating each of the answer choices into a conditional (which is great!), but then focusing mostly on the RESULT of that conditional. I think it's far more useful to focus on the TRIGGER of each conditional to begin.

Is this saying that everyone who rejects X would also reject Y?
Rejects the belief that society's future will be determined... -> ~Believe Individuals cannot have an effect on it
-Would this also be wrong because it has the conclusion/premise backwards?
You've got the conditional correct!
When you say "has the conclusion/premise backwards", do you mean that this answer takes something that is the RESULT of a conditional in the conclusion, and tells us what happens next? Because that's a great way to look at it, if so!
We don't care what gets triggered once someone DOES reject the vast historical forces thing - we only care about
getting to that result. (B) gives us what happens NEXT, and that doesn't help my argument.
einuoa Wrote:C) Feels too helpless to act to change society -> should reject the belief that its future will be determined...
-This is wrong because the last part of the answer connects to much, the future will be determined by vast historical forces that individuals are powerless to change?
I'm not entirely certain what you mean by 'connects too much'. The result of this conditional is *exactly* what we are looking for in the conclusion. The problem here is that the TRIGGER portion of the conditional does not match the argument. This idea triggering
when people are helpless doesn't tell me anything about what happens to people who
want to improve society.
Notice that the conclusion of the argument begins with "If you want to improve society". Where the heck did THAT come from?! Ideally, we're going to get something that connects that concept as a trigger.
Now, if you have that in your crosshairs, then you can notice that only (D) gives you a trigger that matches: "No one who wants to improve society..."
Sometimes diagramming each answer out is necessary to be certain of your eliminations. But sometimes, we can shorten our process substantially by targeting what kind of answer will connect the existing dots! Zeroing in on "if you want to improve society" as a trigger is a great way to do just that.
Please let me know if this completely clears up the confusion!
