A couple of writing (grammar) questions

<p>1 ) Oprah Winfrey has the distinction of having promoted the sales of more serious contemporary novels than (any) talk show host</p>

<p>Book says error is in the work (any), explanation plz ?</p>

<p>2) The Bronte Myth, Lucasta Miller's study of the three British novelists, attempts to trace the historical route by which Charlotte and Emily Bronte (and, to a less degree, Anne) became popular cultural icons</p>

<p>Book says error is in (to a less degree), explanation plz ?
btw, the brackets in the question are part of it, not added by me</p>

<p>Last question, is it a good method to improve reading score by answering reading tests in prep. books then picking out the hard words and memorizing them ?</p>

<ol>
<li><p>I think it should be “any other”.</p></li>
<li><p>Should be “to a lesser degree”.</p></li>
</ol>
