Sorry about those things! For the first, a good reword would be something like "Fortunately,&nbsp;Shojaa-ud-Daulah and&nbsp;Mohammad Kuli Khan did offer their support. Shah Alam would have help in his efforts to regain his power."&nbsp;<br /><br />For the second, I would just delete the sentence. You could also offer the explanation that you gave me, that this &nbsp;"One explanation for this use of materials that were already in use elsewhere is that Shuja-ud-Daulah was making&nbsp;an effort to save costs in a rapidly depleting empire." That way you sum up the idea, rather than simply mentioning it and moving on. It's not necessary, but it could read more clearly (insofar as readers won't have to make their own conclusions).
