Why did it have to emphasize that c is block length 1?

comment Generalizing a CBC-MAC collision with a common final message block
Okay. But I still don't know what the question is asking. What does "most general class of messages" mean? Do I need to talk about what c is?

So if $\\ \\ CBC-MAC(x) = t \\ CBC-MAC(y) = t' \\ Then CBC-MAC(x || y \oplus t) = t' \\$ If y is block length 1 correct?
