Question

if the wrong word is used below, change it. if there is no error, click \submit answer.\ if imelda had checked her voicemail, she would of known that i found her pet turtle.

Explanation:

In the sentence, "would of" is incorrect. The correct phrase is "would have" because "would have" is the proper contraction - related or modal - auxiliary + main verb structure for conditional perfect tense here. "Of" is a preposition and does not fit grammatically in this context.

Answer:

Change "would of" to "would have". The corrected sentence is: "If Imelda had checked her voicemail, she would have known that I found her pet turtle."
