Writing question

<p>BB pg 661 # 26.</p>

<p>John Edgar Wideman is regarded to be one of the most talented writers of the late twentieth century and is often compared to such literary giants as Ralph Ellison and Richard Wright. No error</p>

<p>I understand why B would be the correct answer somewhat, but when would be the right time to use "to be" in the same context??</p>

<p>The proper idiom would be "regarded as."</p>

<p>However, "to be" is usually used with "known to be."</p>

<p>Ah I see. The idioms are "regarded as" and "known to be", so never "known as"??</p>

<p>It can be "known as." Actually it can be "known as/to be/for" depending on how it is used in context.</p>
