Official Explanation
“Even” suggests that the first blank describes the sort of thing you might otherwise expect a thrill seeker to find attractive. These patrons do not want “danger,” so you could just reuse that word for the first blank. “Peril” is the best choice. Although “titillation” does describe a sort of thrill, it is not negative, nor does it suggest danger. “Lavishness” suggests luxury, not danger, and so does not fit either. The third word is probably easier to anticipate than the second, so skip ahead. “In fact” suggests that you want a word that means seems to be unsafe, and the description of the “thrill-seeking visitors” suggests that you want something, well, thrilling. “Terrifies” is the closest choice. “Satisfies” yields a perfectly fine sentence, but it does not contrast with “perfectly safe.” “Mollifies,” which means to sooth or pacify, is the opposite of what the thrill seekers want. The second blank, then, requires something like imitation, and “simulacrum” is the closest synonym among the answers. Using a “complement” here would imply something that partners with danger, which doesn’t match the meaning of imitation of danger. Similarly, an “abettor” of danger would be an aid or a helper, which doesn’t fit the intended meaning either.
