Question

if the wrong word is used below, change it. if there is no error, click \submit answer.\ ernesto de la cruz could of gone skiing, but he chose to read a book instead.

Explanation:

The phrase "could of" is incorrect. The correct phrase is "could have" because "could" is a modal verb and should be followed by "have" (in the perfect infinitive structure "could have + past participle") to indicate a past possibility. "Of" is a preposition and does not fit here.

Answer:

Change "could of" to "could have". The corrected sentence is: "Ernesto de la Cruz could have gone skiing, but he chose to read a book instead."
