<p>Many people (agree) that the full artistic (potential of) jazz was first (realized) in recordings made by Louis Armstrong with the band (known as) the Hot Five. </p>
<p>(Had) I known that we (would be) walking the (fifteen blocks) from the movie theater to the restaurant, I would (of) worn more comfortable shoes.</p>
<p>The combination of the refined and the rudimentary (were reflected) in the medieval castle, (where) rooms (hung) with rich tapestries were poorly heated and (furnished with) plain benches.</p>
<p>Can someone please explain what the answers are and WHY?</p>
<ol>
<li>I think no error? </li>
<li>“of” is wrong. It should be “have.” Usually, in conversations, people say “I would OF” instead of “I would HAVE” because they slur the words.</li>
<li>“were reflected” should be “was” because it is referring to the COMBINATION (singular).</li>
</ol>
<ol>
<li>would have. Common diction error. When people say would’ve, it sounds like they are saying would of.</li>
<li>was reflected. Combination…was Subject verb agreement.</li>
</ol>
<p>I don’t think I see anything wrong with the first sentence… I might be mistaken. I’ll think about it more…</p>
<p>Thanks for the explanations! The answer to the first question is no error. But what I don’t understand what’s the difference between “would be” and “will be.” Why is “would be” correct?</p>
Because people still agree now (in the present) about something that happened in the past.
Ex: My wife and I agree that we should not have invited her schizophrenic aunt to our wedding.
Ex2: Most scholars agree that Isaac Newton was not hit on the head by a falling apple at any time during his life.
