Not sure if this will help, but I struggled with the same thing on this question. It helps to think about it like this for me:

For the sentence, “Pursuing the good life is not possible without social integrity,” the idea is that social integrity is necessary for pursuing the good life. In other words, if someone is pursuing the good life, then they must have social integrity.

So the conditional would be:

Pursuing the good life → social integrity

This means that pursuing the good life is the sufficient condition, while social integrity is the necessary condition. You can think of social integrity as the larger umbrella: pursuing the good life requires it, but social integrity may include many other things beyond just pursuing the good life.

@Kevin_Lin But wouldn't "no parrots are clever" ignore the possibility "that one parrot could be clever" since the lower bound for quantifier 'some' is more than one?

me too! i think its when i don't fully complete the lessons in the study plan it changes so technically im not behind but i would rather see what haven't done and keep the lessons as is without them shifting
