Help Detective Paws complete her incident report regarding the world's clumsiest cat burglar. Choose the correct verb phrases to complete the implied conditionals.

"But for that tragically timed sneeze, the suspect would have escaped unnoticed into the night. Furthermore, he foolishly wore tap shoes to a heist; otherwise, his footsteps might have remained entirely silent."

"But for that tragically timed sneeze, the suspect would have escaped unnoticed into the night."

The phrase "But for..." acts as an implied condition meaning "If it had not been for...". Because this refers to a hypothetical past event, the main clause requires the perfect conditional (would have + past participle).

"Furthermore, he foolishly wore tap shoes to a heist; otherwise, his footsteps might have remained entirely silent."

The word "otherwise" implies the condition "if he hadn't worn tap shoes." Since the condition is contrary to a past fact, the result requires a past modal structure (might have + past participle).
