How would you suggest to list centuries here:
Suspended hyphen:
In the late nineteenth- and early twentieth-centuries...
Separated by commas:
In the late nineteenth-, and early twentieth-, centuries...
Spelled out in full:
In the late nineteenth and early twentieth centuries...
Or, finally, condensed:
In the late 19th and early 20th centuries...
Any help, or reference to style manuals would be hugely appreciated!
