<p>in death of a salesman Willy Loman mistankenly believes that his sons have no flaws, (believing which leads) to many problems for the entire family.</p>
<p>the answer is:</p>
<p>(a belief that leads)</p>
<p>so it goes like this:</p>
<p>in death of a salesman Willy Loman mistankenly believes that his sons have no flaws, (a belief that leads) to many problems for the entire family.</p>
<p>but, there is no conjunction after the comma so why it's not a comma splice?</p>
