Exercise 2 solution All sums were checked in Python. (a) 1909 - 1887 = 22 years. Tonnies's first edition (1887) came 22 years before Cooley's Social Organization (1909), so the community/society idea was published first. (b) 1921 - 1818 = 103 years. The word "Bureaucratie" was in English print long before Weber's Economy and Society (1921). (c) 100,000 / 187,369 = 0.5337..., which is 53.4 percent (one decimal place) of the Bureaucracy page. (d) 187,369 - 100,000 = 87,369 characters were not read. Caution: roughly 46.6 percent of the page was never seen (my arithmetic: 100 - 53.4), so a section on criticism, or on any other topic, could sit in that unread part. If the chapter said nothing about a critic, that shows only that the critic did not appear in the first part, not that the page has nothing to say. That is why the chapter says it makes no claim from the Bureaucracy page about Parkinson or Michels.
