The principle I thought was
Premise: Not buy-> cancel
Conclusion: feel worth preserving-> buy.
So the gap is feel worth preserving-> NOT cancel

So that's why I chose D. But the answer is B. And I can't still find out why D is wrong and B is an answer.
Am I missing something?
Please someone explain me why D is incorrect and B is an right.

Oh and what's the differences between A and B? (They look almost identical to me.)

Thanks!

In this principle justification question, you aren't looking for a gap in the argument. You are looking for a principle that, if applied, would justify the course of action recommended in the stimulus.

The difference between A and B is that A talks about "one" and B talks about many. So which one is right? Well the stimulus says that shows will be cancelled if people *generally* fail to buy advertised products. This implies that we need a principle that talks about more than one person failing to buy products, and A says only "unless one took certain actions". This is the wrong sufficient trigger because the principle isn't talking about shows being cancelled if one person doesn't buy, but if many people generally don't buy.

Hope this helps!
