Question

The next level of idea importance, or the "second level of subordination" must be _____. units chapters topic sentences chapter subdivisions

Ideas should be ordered from general to specific, likewise from abstraction to concretion; the more general the idea the higher the level of significance, which provides logic to the work. Thus subdivisions ought have affinity with the whole.

Chapter subdivisions are chapter within chapters, with a chapter being one of the major divisions. Therefore the "second level of subordination" is "Chapter subdivisions"

Answer 2

The second level of subordination is called 'Chapter SUBDIVISIONS.'  It follows 'chapter' which is preceded by units. Chapter subdivisions is then followed by topic sentences. So the order will be: Units, Chapter, Chapter subdivisions, and Topic sentences.
