Question

(LC)Which sentence below shows correct use of em dashes?

Answer 1

Answer: C) If the cat meows one more time – I know he will – I am going to have to get the treats.

Explanation: One of the most common uses of dashes is to introduce (and conclude) an additional information in a sentence or paragraph. In the given sentence, the additional information is "I know he will"  (notice that if we remove this information, the sentence still makes complete sense), so that phrase should be between dashes, therefore, the correct answer is the corresponding to option C.

Answer 2

"If the cat meows one more time – I know he will – I am going to have to get the treats."

This is the answer because, they are putting in another thought in the sentence. They are interrupting themselves, putting in another thought. They are also continuing after they interrupted, all in the same sentence.
