Hi there,

Could you please explain to me why (B) is wrong?

[Adam Tyson]

For sure, Alex! The question asks about what "distinguishes between" two types of coordinating rule, and that means we are looking for something that makes them different from each other. Answer B describes a similarity rather than a difference, because both of the examples involve conformity to certain agreed-upon standards. Since that's a similarity, it cannot be what distinguishes them!

Answer A shows that difference, as described at the beginning of the last paragraph. The "which side of the road" example is one in which any rule will do, so long as there is one. But the steroid rule is different, because the harm goes beyond just the lack of coordination. That's what "distinguishes" those two examples, because that's what makes them different.
