-and some student sociologist might care to base his thesis upon the phenomenon-
Hello,everyone
Here I am feeling confused about a sentence in the following paragraph : (
That the equipment of modern camping becomes yearly more sophisticated is an
entertaining paradox for the cynic, a brighter promise for the hopeful traveler who has
sworn to get away from it all. It also provides-and some student sociologist might care to
base his thesis upon the phenomenon -- an escape of another kind.
I wonder know what the differences are between the use of" em rule" and""comma" ,and the meaning of "--and" in this paragraph, Personally,the structure of this sentence is a little strange for me to get understand, Could I say like : It also provides, some student sociologist might care to base his thesis upon the phenomenon. an escape of another kind.
(PS: Could I say: "another kind of escape" as well ? )
Thanks a lot for your time to read my message : D
