<p>For this writing question:
Susan is best known for her historical accounts that focus on ordianary lives, especially that of women, rather than on other social events.</p>
<p>In this sentence, the correct answer is that "that of" is wrong, but I don't understand why it is wrong.</p>
<p>The phrase “that of” is incorrectly modifying lives"</p>
<p>It should be “those of,” since it modifies “lives” and thus needs to be plural.</p>
<p>Since “that” is singular, “that of women” means “the life of women” (“life” is singular), which doesn’t make sense. “life” should be “lives,” and “that” should be “those.”</p>
<p>Thanks everyone - my grammar skills are not that good. And, I have just started practicing for SAT writing.</p>
