A: This answer choice incorrectly refers to the singular noun "the federal government" with the plural pronoun "their"; please remember, collective nouns ("government" in this case) are always singular. Further, Option A alters the meaning of the sentence through the phrase "was dependent on tariffs to be"; the construction of this phrase illogically implies that the federal government depended on tariffs
for the purpose of being its main source of revenue; the intended meaning is that the federal government depended on tariffs
as its main source of revenue; remember, the infinitive verb form ("to + base form of verb" - "to + be" in this sentence) is the preferred construction for referring to the purpose or intent of an action.
