What's wrong with that?

The instructions mention "the word or expression that, of those given,
best completes the statement or answers the question."

Assuming a positive coefficient seems much better than assuming the
opposite.  That's certainly the rule rather than the exception.

 -- There is theoretical evidence supporting such a rule:
    electron-phonon scattering and all that.

If this were a classroom situation I would say "come in tomorrow
with a non-perverse counterexample and I'll give you 10 points
extra credit".
