<p>I had difficulty with this writing question from the McGraw Hill book. In the nineteenth century, a few respected thinkers “became convinced”(A) that nations would not be able “to coexist” (B) peacefully “until” (C) all of the world’s cultures “adopted” (D) a single mutual language. “No error” (E)</p>
<p>The correct answer was choice E, “no error”. </p>
<p>I thought choice D was incorrect and should have been “would adopt” as its describing something that will occur in the future. How come the original sentence doesn’t need to be changed?</p>
