Correct, but remember that the parameters are like "dial settings" on a
much more complex structure, Universal Grammar (UG), which we all have
in our heads, it seems, at birth: we don't lear UG. We just learn which
particular parametric variant of UG we happen to be speaking: We don't
learn how the radio works; we just learn which station we happen to be
tuned to...

But we DO need to "know" UG, otherwise the parameters would be no help;
indeed they are parameters OF UG.

Good response, and nearly an A: For that you need to sort out the
relation of parameter setting to UG, the poverty of the stimulus, the
lack of negative evidence, hence the unlearnability of UG...
