This question is regarding the sound change theory. Could someone explain why the answer is D?
Thanks!

Re: PT 27 Section 1 LR #16
First, you have ask yourself what do we know?
We know that according to the new research, sound change is not gradual. But we also know that classical theory relies on the assumption that sound change is gradual. So if we take the new research to be correct, we absolutely know that CLASSICAL THEORY cannot be correct.
The conclusion on the other hand says that SOUND CHANGE THEORY in general must be discarded. There is a theme shift here from classical theory being wrong to sound change theory being wrong.
So what connects these two things? Well, if sound change theory was dependent on classical theory then if we must discard classical theory we must also discard sound change theory. In essence, it's a sufficient assumption flaw which is what answer choice D attempts to pick up on.
