Many scholars have theorized that
    economic development, particularly
    industrialization and urbanization, con-
Line    tributes to the growth of participatory
 (5)    democracy;  according to this theory, it
would seem logical that women would
both demand and gain suffrage in ever
greater numbers whenever economic
development expanded their economic
(10)    opportunities.  However, the economic
development theory is inadequate to
explain certain historical facts about the
implementation of women’s suffrage.
For example, why was women’s suf-
(15)    frage, instituted nationally in the United
States in 1920, not instituted nationally
in Switzerland until the 1970’s?  Indus-    
trialization was well advanced in both
countries by 1920:  over 33 percent
(20)    of American workers were employed
    in various industries, as compared
    to 44 percent of Swiss workers.
Granted, Switzerland and the United
States diverged in the degree to
(25)    which the expansion of industry coin-
cided with the degree of urbanization:
only 29 percent of the Swiss population
lived in cities of 10,000 or more inhabi-
tants by 1920.  However, urbanization
(30)    cannot fully explain women’s suffrage.
Within the United States prior to 1920,
for example, only less urbanized
    states had granted women suffrage.
Similarly, less urbanized countries
(35)    such as Cambodia and Ghana had
voting rights for women long before
Switzerland did.  It is true that Switzer-
land’s urbanized cantons (political
subdivisions) generally enacted
(40)    women’s suffrage legislation earlier
than did rural cantons.  However,
these cantons often shared other
characteristics—similar linguistic back-
grounds and strong leftist parties—that
may help to explain this phenomenon.

Q5:
The passage states which of the following about Switzerland’s urbanized cantons?
        
A.    These cantons shared characteristics other than urbanization that may have contributed to their implementation of women’s suffrage.
B.    These cantons tended to be more politically divided than were rural cantons.
C.    These cantons shared with certain rural cantons characteristics such as similar linguistic backgrounds and strong leftist parties.
D.    The populations of these cantons shared similar views because urbanization furthered the diffusion of ideas among them.
E.    These cantons were comparable to the most highly urbanized states in the United States in their stance toward the implementation of women’s suffrage.
