choose the word or group of words that best completes each of the following sentences:
If she had known, she wouldn't have come,________?
Answer Details
The word that best completes the sentence is "wouldn't she".
This phrase is a conditional sentence, where the first part "if she had known" states a hypothetical situation, and the second part "wouldn't she have come" states the result of that situation.
The word "wouldn't" is a contraction of "would not", and it expresses a negative possibility. So, the sentence as a whole means "If she had known the information, she wouldn't have gone to the place."
In summary, the word "wouldn't she" is the most appropriate choice to complete the sentence because it conveys the idea of a negative possibility in a hypothetical situation.
