So how do we know if we have "advanced logical reasoning"? Through a diagnostic? If so what diagnostic score should tell us we don't need to do the CC?

Starting today, took diagnostic last weekend. So excited!

Wouldn't a tadpole that has increasing its own total genetic representation as a priority want to preserve itself over preserving its siblings? I mean, that seems to square perfectly with the inclusive fitness theory, so why would C not be correct?

I heavily disagree with the explanation. Research is literature. Passage A mentions research on control. That's explicit enough. The "literature" referenced in passage B wasn't explicitly said to be about control, rather just the impact of the plant. I think that's why Passage B can't be said to mention it.

But the only thing cohesiveness does to self-censorship is lower the likelihood of self-censorship out of fear of punishment. The passage never says cohesiveness lowers the likelihood of self-censorship in general, so how could we know that B's right?

If you're confused by this, just move on. The explanation overcomplicates things
