While our parents were working, Mrs. Kent watched <u>us.</u>
they or we, wouldn't make sense when you read the sentence.

<span>The beginning of an MLA citation is "lastname, firstname". B and C don't follow this, so you can eliminate them. Then you notice at the end of the citation, the pages cited has to be preceded by a "pp". Choice A doesn't follow that, so we can also eliminate that choice. The remaining choice "D" is a correct citation.
