Expalantion

The phrase “equally public” gives you a clue that the legislator’s approval was also highly publicized, or heralded.

Ratified, which means “officially approved,” would be redundant in this context. For the second blank, you aren’t given much of a clue about what the meaning should be. When this happens, only one answer choice will make sense (and usually that correct choice won’t add much to the sentence), while the other, incorrect answer choices will drastically change the meaning. Here, appropriated, which means “allocated” or “assigned,” fits nicely and doesn’t add any unintended meaning. Neither adduced, which means “cited as evidence,” nor adumbrated, which means “reported in an outline,” is fitting.

Heralded, appropriated.
