My gripe is between choices (C) and (D).
(C)
I like C because the passage seems to be split into describing two sets of circumstances where controversy has arisen over "privacy" in workplaces. The first in regards to internal destruction of emails in public companies, and the later on snooping of online communication in public companies. This seems to at least imply that the solutions must make a distinction between the two. Namely, the distinction between the responsibilites one has to their employees vs that of a governments constituents. I suppose this may not be the main point, but I have issues with D.
(D)
This choice states that "no clear general anwsers" exist in either private or public in regards to the privacy of electronic mail. What about lines 49-52 the "reasonable expectation of privacy" standard? I see, and concede, lines 7-8, but how can the main point be no general anwsers exist when a standard is explictly mentioned?
