Pg 317 (329) - Q2
Here, we're talking about Rachel Carlson's book which described a world made lifeless by all these hazardous pesticides. What would she be doing with a campaign to do something _______ something of the indiscriminate use of such substances. Well, she'd be wanting to limit or control it(those are the only two negatives possible), but she wouldn't be protesting against that group as you find in B. So, the answer is D, she was inspiring a grass-roots campaign to control the indiscriminate use.
