no clear indication as to the extent of this usage.
nice!! Good point. In critical thinking, they refer to both "depth" and "breadth" of thinking.
With breadth, you think widely and inclusively so that you do not miss possibilities.
At the end of the first paragraph, you can succinctly state your main point or list a few points that comprise your argument. For example:
The claim is questionable for two main reasons: The extent to which human bodies were used as models is not known, and the value of the miniatures may not be greater because people value different aspects of the art.
By listing your points at the end of the first paragraph, the essay will have better structure, and that is what Rajesh is talking about, too.
Anyway, this is well written, for sure.
