Complete the secret agent's mission report on a rather incompetent villain by choosing the most appropriate sentence adverb for each blank.

The villain's doomsday laser was mercifully unplugged by the night shift cleaners, saving the entire eastern seaboard from vaporization. The mastermind had evidently forgotten to pay his henchmen, considering they all walked out on strike just minutes before the attack. This organization is arguably the most incompetent evil syndicate in history, although a few rival villains might dispute that title.

The villain's doomsday laser was mercifully unplugged...

"Mercifully" expresses the speaker's relief that a terrible event was avoided (saving the seaboard).

The mastermind had evidently forgotten to pay his henchmen...

"Evidently" is used when deducing something based on clear evidence (the fact that the henchmen went on strike).

This organization is arguably the most incompetent evil syndicate in history...

"Arguably" means that a strong case can be made for this claim, which fits perfectly with the concession that rival villains "might dispute that title."
