<p>27) For many students, the realization that his or her academic success can be affected by dietary habits comes as a great surprise. </p>
<p>-The underlined portions are: his or her (choice a), affected (choice b), by dietary habits (choice c), comes (choice d). </p>
<p>My book's explanation says that choice a contains the error, and that ''them'' should really be there. I understand why ''his or her'' is wrong, but is ''their'' acceptable, too? Why ''them''?</p>
<p>Are you sure your book says that “them” should be in place of “his or her?” </p>
<p>The correct sentence: For many students, the realization that THEIR academic success can be affected by dietary habits comes as a great surprise.</p>
<p>students is plural and hence requires a plural pronoun; his or her is used to replace singular nouns so the correct answer should be the plural pronoun “their” not “them”</p>
<p>Yes! I am sure it said, ‘‘them’’!
Screw my book!</p>
<p>what’s the name of the book you’re using?</p>
