单选题
The slogan "scientific truth is a matter of social authority" has become dogma to many academic interest groups who have been______ themselves to substitute their authority for that of the, practicing scientists.
【正确答案】
B
【答案解析】解析：B项exerting意为“尽(力)，施加(压力等)，努力”，exert oneself(to do sth．)表示“努力，尽力”。根据空格处的意思“这些组织一直竭尽全力要替代前沿领域的科学家们的权威”，故选B。A项grudging“不给予”；C项swarming“涌往，挤满，密集”；D项detesting“厌恶，憎恨”，均不符合题意。
