Can you fill in the blank?
If a food label indicates that a food is mostly carbohydrate, it does not mean __________is a good food to eat.

That it-after reading the sentence, we realize there are multiple sub-sentences. the sentence starts with a condition which has the main verb indicates. it is followed by the connector that and another complete sentence. this connector joins both sentences. then, we see a comma indication the end of the first part of the condition. we start again with a subject and main verb. after the blank there is a linking verb and a predicate. this leads us to anticipate a subject and possibly a connector, too. it is not letter d because it is only a connector. it is not letter b because it is only a connector as well as being the wrong kind. it is not letter a because the connector is incorrect. the proper answer is letter c.
