How would you rewrite the following claim to remedy problems of ambiguity?

Question

Do not assume that common sense by itself solves the problem.

"Two million times a day Americans love to eat,
Rice-a-Roni -- the San Francisco treat."

ANSWERS:

1. Two million times a day Americans love to eat ...
2. Two million Americans eat Rice-a-Roni.
3. Be like two million San Franciscans and eat Rice-a-Roni.
4. Two million people per day in San Francisco eat Rice-a-Roni.

IThink the answer is no. 4

Answer 1

I don't think 4 is right because the statement says that Americans (not just San Franciscans) love to eat it.

Frankly, I don't like any of the choices. If you must choose, I'd go with 1.
