this is from the freely available June 2007 LSAT, so i will go ahead and type it out here.

philosopher: an action is morally right if it would be reasonably expected to increase the aggregate well-being of the people affected by it. an action is morally wrong if and only if it would be reasonably expected to reduce the aggregate well-being of the people affected by it. thus, actions that would be reasonably expected to leave unchanged the aggregate well-being of the people affected by them are also right.

C) any action that is not morally wrong is morally right.

thanks in advance

Increase --> MR
MW --> Decrease

Conclusion: Unchanged --> MR

The conclusion works if there are only two possibilities, that an action is either morally right or morally wrong. This in turn forces us to eliminate the alternate possibility to the conclusion presented: that any action which leaves things unchanged is morally wrong. Hence (C) is the correct answer.

this sounds a lot like incorrect answer choice (B). Can someone explain what B means in this context? thanks!

I guess (B) errs because it does not link in the conclusion's idea of "actions that would be reasonably expected to leave unchanged the..." ?
