Here, Z MUST be included in the game, so there is no "if" about Z. It is in, and it is a classic, so the block just makes more sense. Consider the contrapositive - if Z is not a rock classic, then Z is not included. Is that even an option? Nope! So there's no point to using a conditional approach. Save those for when the sufficient condition isn't guaranteed to occur!Hi Adam,

There is one G, and it must be a 10, but there could be another 10 out there that is not a G. But you can combine these approaches by writing a conditional that shows G as sufficient and a G/10 block as the necessary condition, which would also be accurate!Hi Tyson I think what I'm asking is in regards to the "Z is a Rock Classic" because that is drawn as a block which you explained why above however the "g" rule is written as a conditional in the textbook.
