as for your first question, you have totally copied the sentence incorrectly in a way that fixes the original error. what that means is that you can no longer claim that our book thinks it is an incorrect sentence..
second, awkward does not mean incorrect. in other words, do not EVER eliminate a choice because you think it is awkward unless there is absolutely nothing else on which you can base a decision. even then, awkward still does not mean incorrect; it just renders the choice less desirable than another grammatically correct response..
Thanks Tim, really appreciate for your reply. Doubts are clear now.
