Hi @hfatima1,

Thanks for the question! So what exactly is the proposition above? It’s an if-then statement, right? So if someone has evidence an act will benefit other people and performs that act to benefit them, then one will generally succeed. So we want to either look for the sufficient condition being present, and also the necessary condition, or say that a lack of the necessary condition means that the sufficient condition isn’t there either.

So let’s take a look at (B). It’s certainly true that the sufficient condition is fulfilled here. The government study would be the evidence, and the government followed through. So it should’ve succeeded, but it didn’t! We’re missing the necessary condition, and so (B) doesn’t count.

Now take a look at (C). So Betsy overhears this contractor. But that counts as evidence! The contractor is a pro and knows what’s up, so Betsy now has evidence that an act (changing the filter) will benefit other people (her daughter). She then does it, and it works! That goes along with the principle, making (C) the right answer. This answer doesn’t turn on the strength of the evidence; it doesn’t matter that you might think the evidence is just “overheard.”

Hope this helps! Feel free to ask any other questions that you might have. D
