Edtorialist: News media rarely cover local politics thoroughly, and local political business is usually conducted secretively. These factors each tend to isolate local politicians from their electorates. This has the effect of reducing the chance that any particular act of resident participation will elicit a positive official response, which in turn discourages resident participation in local politics.
Which one of the following is most strongly supported by the editorialist's statement?
D. More-frequent thorough coverage of local politics would reduce at least one source of discourgement from resident participateion in local politics.
B. Local political business should be conducted less secretively because this would avoid discouraging resident participation in local politics.
我觉得这道题是个FL, D是把充分条件" news media rarely cover local politics thoroughly" 取非了, 充分条件取非怎么能得到必要条件" reducing....elicit a positive official response" 也取非呢?
